STAT
ELECTROMAGNETIC CONTACTORS WITH D.C. CIRCUIT
CONTROL Series KU 500, KTH 500 AND Type KMB 521
The Contactor is an electrical single-stage de-
vice, which is designed, mainly, for frequent
opening and closing of electric circuits.
The following Electromagnetic Contactors with
D. C. circuit control are included in this cata-
logue:
Series Ku 500 D. C. Contactors, single-
pole with normally open and normally closed
contacts with or without magnetic arc blow-out.
Series KUL 500 ----- A. C. Contactors, 2-pole,
with normally open contacts, with or without
magnetic arc blow-out.
Type KMB 521 D. C. Contactors, 2-pole,
with normally open contacts, with arc blow-out.
The Contactors included in this catalogue have
magnetic systems suitable only for operation from
a D. C. control circuit.
The Contactors are manufactured in accordan-
ce with USSR Standard COST 2758-53 and rated
for operation under the following conditions:
a) at an elevation above sea-level, not more
than 1000 m;
b) at an ambient temperature not higher than
+35?C and not lower than -----40'C (at tempera-
tures lower than ---15?C non-freezing lubrication
should be used, where it is required by the (Ie-
sign).
The Contactors are available in the open type,
without enclosures and, therefore, are not suitab-
le for operation under the following con(litions:
a) in an atmosphere filled with current-car-
rying dust (for example coal, flour, etc.);
b) in an atmosphere of high humidity or in
locations not protected against the penetration
of water;
c) in an atmosphere containing corrosive gases
and vapours injurious to metal and insulation.
Enclosing the Contactor in a housing changes
the heating conditions and the characteristics of
the Contactor.
The Contactors will reliably operate when the
control circuit voltage on the operating coil is
reduced to 85% of its rated value. The operating
coil can operate continuously at a voltage equal
to 105% of the rated value and allows a voltage
increase up to 110"/0 of the rated value. Opera-
tion under such conditions, however, reduces the
service life of the operating coil.
The Contactors, without an arc blow-out arran-
gement, are not suitable for interrupting power
circuits.
The Contactor should not be used in place of
automatic circuit breakers as they are not de-
signed for the interruption of short-circuit cur-
rents of considerable value.
The insulation of these Contactors with excep-
tion of the asbestos-cement arc blow-out chutes
withstands an A. C. one-minute test voltage of
2000 V at a frequency of 50 c. p. s.
The insulation of the arc blow-out chutes
wiithstands a 1000 V test voltage.
All terms and definitions used in the present
catalogue are in accordance with USSR Standard
COST 2774-44.

SINGLE-POLE, WITH NORMALLY OPEN AND NORMALLY CLOSED CONTACTS, WITH
OR WITHOUT MAGNETIC ARC BLOW-OUT
100, 150, 300 and 600A; up to 600 V; open type
APPLICATION AND CLASSIFICATION
D. C. single-pole Contactors, series KU 500,
are designed for opening and closing D. C. elec-
tric power circuits at voltages up to 600 V. These
4 * Normally open Contactors of the 2nd size and nor-
mally closed Contactors of all sizes are suitable for
operation in D. C. circuits at voltages up to 443 V. For
600 V installations normally open Contactors of the 3rd
size should be used instead of the 2nd size. Normally
Contactors are designed for frequent opening- and
closing operation (up to 1200 times per hour)
and are suitable for heavy duty operation in me-
closed Contactors for voltages higher than 441) V for
light-duty operation (in comparison with those given in
the catalogue), upon agreement with the Works, are
available with characteristics other than those given in
this catalogue.

tallurgical, transport and other industrial instal-
lations.
The Contactors are classified according to:
1. rated current of the main contacts: 100 A,
150 A, 300 A and 600 A;
2. design of main contacts and arc blow-out,
with n. o.* contacts, without arc blow-out; with
n. c. contacts and arc blow-out; with n. c. con-
tacts without arc blow-out;
3. voltage of operating coil: 110, 220 V;
4. interlocks: Contactors without interlocking
contacts; Contactors with two n. o. and two n. c,
interlocking contact circuits;
5. connection of wires: back, front connection;
6. mounting: without panel, on insulated panel.
N. o. contactors with arc blow-out are used as
line contactors, reversing contactors, accelerating
contactors, etc.
N. o. and n, c. Contactors without arc blow-
out are used when the Contactor does not break
the power circuit or when the Contactor inter-
rupts a power circuit at extremely low voltages
on the contacts (accelerating contactors in non-
regulated drives, etc.).
N. c. Contactors with arc blow-out are used in
dynamic breaking circuits, or emergency switch-
ing of lighting, etc.
DESIGN
A. CONTACTORS WITH NORMALLY OPEN CONTACTS
Magnetic Circuit. All the parts and assemblies
of the Contactor are mounted on the II-shaped
main magnetic circuit bracket. A bent armature
is inserted into a rectangular opening of the main
bracket. The armature is pivoted on the knife
edge at the edge of the rectangular opening in
the main bracket. The retainer prevents the arma-
ture from leaving the knife edge. Spring forces
the end of the armature against the main bracket
when the operating coil is de-energized.
Movable Centact. The armature bracket which
holds the flat movable contact is mounted on the
armature. The contact pivots on the knife edge
of the armature bracket and is forced by the
contact spring against the supporting surface of
the armature bracket.
A flexible connection is fastened to the mo-
vable contact. It connects the contact with the
bar terminal of the movable contact.
Stationary Contact. A molded plastics base
is fastened to the main bracket. The stationary
contact is fastened to the base. Current flows to
stationary contact through the arc blow-out coil,
one end of which is the bar terminal of the statio-
nary contact. The other end is connected to the
stationary contact.
Arc Blow-Out Assembly. Series arc blow-out is
used in 500 Contactors. The arc blow-out
chute is arranged on the horn of the stationary
contact and by the aid of the arc blow-out cheeks
is assembled into a single unit. The horn of the
stationary contact serves also for fastening the
chute to the Contactor.
Operating Coil. The operating coil is wound on
an insulated thin-walled steel bobbin. This provi-
des for high mechanical strength of the coil, lo-
wers the. temperature rise, as compared with
* The terms ?normally open? and ?normally closed?
will be hereafter abbreviated to /sm. o.? and ?n. c.?, respec-
tively.
2
coils not provided with bobbins, and insures con-
siderably longer service life.
A flat spring is arranged on the. core between
coil bobbin and the lower part of the main
bracket. Teeth of the spring enter corresponding
slots of the bobbin. The edges of the spring are
crimped on the side opposite the teeth, to position
the coil relative to the main bracket of the mag-
netic circuit.
When the Contactor is for front connection, the
terminals of the arc blow-out coil and the mo-
vable contact are bent to one side.
Interlock Contacts. The interlocks are fastened
to the main bracket of the magnetic circuit by a
plate which also serves as a support for the ar-
mature restraining spring.
B. CONTACTORS WITH NORMALLY CLOSED
CONTACTS
The angle-shaped magnetic yoke and the angle
are assembled by bolts and columns into a single
unit, which serves as a frame for the Contactor.
The stationary contact assembly together with
the arc blow-out device are mounted on the
angle-piece (in the same manner as the statio-
nary contact assembly of the Contactors with
n. o. contacts). The bent armature differs from
the armature in the n. o. Contactor in the angle
of the bend. The movable contact assembly is fas-
tened on the armature at the block (as on the
Contactors with n. o. contacts).
The closing spring is situated between the ar-
mature and the flexible connection. It provides
the required contact pressure when the operating
coil is de-energized.
C. CONTACTORS WITH NORMALLY OPEN OR
NORMALLY CLOSED CONTACTS, WITHOUT ARC
BLOW-OUT
Contactors with n. o. and n. c. contacts
without arc blow-out differ from the above-men-
tioned Contactors only in the absence of the arc
blow-out coil and the chute.
D. INTERLOCKS
The interlocks of the Contactors, series KU 500.
are self-contained units which consist of a mol-
ded plastics base and a crosspiece. Two n. o.
and two n. c. stationary contacts are fastened to
the plastics base.
Movable bridge-type contacts with silver-faced
tips are mounted on the plastics crosspiece which
moves forward in the guides of the body.

* Weight of interlocks with two n. o. and two n. c. contacts is 0,25 kg.
The main contacts of these Contactors, without
regard to the rated voltage of the operating coil,
are suitable for operation in D. C. power circuits
at voltages up to 600 V with the exception of II
size Contactors and Contactors with n. c. con-
tacts which are suitable for voltages up to 440 V
(see note in section ?Application and Classifica-
tion?). When two Contactors are used as rever-
sing devices they should be equipped with elec-
trical or mechanical interlocking devices.
Reversing Contactors with mechanical inter-
locks should be placed side by side only. Contac-
tors of the same size can be interlocked (see note
in section ?Mounting, Overall and Installation
Dimensions?).
The value of allowable load depends upon the
operating conditions of the Contactor. When the
Contactors are installed in enclosures, the load
current, in comparison with the nominal rating,
as a rule, should be reduced in accordance with
the type of the enclosure, its volume and the heat
from other equipment situated in the same enclo-
sure. Data concerning allowable loads under va-
rious operating conditions are given in the Table.
When the Contactors operate continuously, the
surfaces of the contacts oxidize and the tempera-
ture rise of the current-carrying parts increases.
27
21
For this reason the value of the allowable cur-
rent, in comparison with the allowable current
for intermittent-continuous duty operation, dec-
reases according to the data indicated in the
Table.
If operating conditions demand that the value
of the allowable current should be retained for
continuous-duty operation, it is necessary to use
silver-faced contacts. The silver face-plates, how-
ever, wear rapidly when interrupting load cur-
rents; therefore they can be used only when the
Contactor is applied for conditions of infrequent
operation. If operating conditions demand con-
tinuous duty followed by intermittent-duty ope-
ration, the silver-faced contacts are not recom-
mended. In such cases the load current should be
lowered, in comparison with the nominal rating,
in accordance with the data indicated in the
Table. When the Contactors operate on repeating-
intermittent duty cycle an increase in the current
rating in comparison with the nominal rating is
allowable only when the number of operations
does not exceed 600 per hour.
When the Contactor interrupts a load current
the arc is thrown out of the arc blow-out chute
to a distance depending on the value of current
interrupted, the voltage on the contacts, and the
character of the load.

* At the 105" ,, value of the rated voltage the Contactors ensure:
a) fifty-time closing and fitty-time opening at ten-second intervals under a load created by a braked electric motor
of a usual industrial series with resistance inserted in the armature circuit. The resistance is determined so as to pro-
vide a value of the current not less than four times the rated current of the contactor.
b) eight-time closing and opening at ten-second intervals of non-inductive load, determined as equal in value to
not less than eight times the rated current.
c) five-time closing for a period of not more than 0.5 sec and five time opening at ten-second intervals of an active
load, determined as equal in value to not less than fifteen times the rated current at the rated voltage of 220 V.
(1) the minimum current interrupted by Contactors with forced arc blow-out, when breaking the circuit of an elec-
tric motor, should not be less than 20" of the rated value.

mical resistance is used. The economical resis-
tance should be shunted at the time when the
coil is first energized. For this purpose, one of
the n. c. interlocks of the Contactor is used. The-
refore n. c. Contactors, as a rule, are provided
with interlocks which are mounted on an insula-
ting panel to which are fastened the auxiliary
resistances in the form of vitrified ceramic tubes.
When the Contactors are to be mounted not on
insulating panels, the auxiliary resistances may
be shipped separately.
At 105% of the rated voltage of the power cir-
cuit, Contactors with n. c. contacts and arc blow-
out will provide fifty-time closing and fifty-time
opening at ten-second intervals of a load. The
load created by a braked electric motor of the
usual industrial series with resistance (inserted
in armature circuit) is determined as equal in
value to not less than a twofold current rating
of the Contactor.

MOUNTING, OVERALL AND INSTALLATION DIMENSIONS OF CONTACTORS
Series KFI 500 Contactors differ from other
available types of Contactors in that they are
completely assembled and adjusted before they
are installed on a panel or in a control unit. There-
fore, Contactors to be used for assembling
complete control units are available without pa-
tick. When assemblin,g,- such units, these Con-
tactors do not require adjustment.
011
panel
These Contactors should be mounted in a ver-
tical position.
When series 500, Contactors are to be
mounted on non-insulating panels, special insu-
lation between the Contactor and the panel must
be provided, as contactor bodies are under vol-
tage.
ORDERING DIRECTIONS
When ordering please state:
I. Full name of the Contactor.
2. Power circuit current and voltage ratings.
3. Contact arrangement and arc blow-out.
4. Type and arrangement.
5. Operating duty.
6. Method of mounting and connection.
7. Are interlocks required?
8. Operating-coil circuit voltage.

A.C. CONTACTORS, SERIES KTI1500, TWO-POLE, WITH NORMALLY OPEN
CONTACTS, WITH OR WITHOUT ARC BLOW-OUT, OPERATED FROM
a D.C. CONTROL CIRCUIT
50, IN, 150 and 300 A; up to 380 V, 50 c. p. s.; open-type
APPLICATION AND CLASSIFICATION
A. C., two-pole Contactors, series KTFI 500, are
designed for the control of heavy duty induction
motors with an operating frequency (opening
and closing the circuit) of up to 1200 times per
hour in combined supply systems of metallurgi-
cal drives, where high mechanical and electrical
resistance to wear are required. Direct current
supply of th,2 Contactor control circuits for me-
tallurp,-ical drives with induction motors provides
for reliable operation of the drive circuit.
The use of D. C. supply for control circuits is
possible because, at the present time, combined
supply is widely practiced for the drives of me-
chanisms in metallurgical plants where, usually,
both A. C. and D. C. supply circuits are available.
For the infrequent case where direct current is
not aVanable, coil circuit supply is possible with
the aid of dry-type rectifiers.
Series KTI-I 500 Contactors in the controls of
A. C. drives with squirrel-cage induction motors
are used for closing and opening the stator cir-
cuit ? stator Contactors, while in drives with
wound-rotor induction motors the Contactors are
used for short circuiting the steps of resistance
in the rotor circuit, ? neutral-point Contactors.
The majority of alternating current heavy duty
drives require reversibility of rotation; this is
realized by stator Contactors.
Two-pole Contactors can be widely used, not
only in A. C. installations, but also in D. C. in-
stallations as line Contactors for two-pole dis-
connection of D. C. motors from the line and
also reversing contactors.
The application of two-pole Contactors for the
cont.' ol of D. C. electric motors as in A. C. dri-
ves increases the reliability and decreases the
overall dimensions of the in
In addition, the application of two-pole Con-
tactors considerably increases safety of opera-
tion since the frame of the Contactor is not under
voltage. In case of accidental contact, the servi-
cing personnel will not undergo danger.
The Contactors are classified according- to:
1. Rated current of the main contacts: 50 A,
100 A, 150 A and 300 A.
2. Arrangement of the main contacts and pre-
sence of arc blow-out: with two n. o. contacts
and arc blow-out, with two n. o. contacts with-
out arc blow-out.
3. Voltage of the operating coil: 110 V D. C.
and 220 V D. C.
4. Interlocks: Contactors without interlocks,
:](ckmt;.ictors with two n. 0. and two n. c. inter-
05. Connection of terminals: back, front con-
nection.
6. Mounting: without panels, on insulating
panels. Contactors with arc blow-out are used
as line Contactors, reversing Contactors (if they
operate also as line contactors), accelerating con-
tactors, etc.
Contactors without arc blow-out are used
when the Contactor does not break the power
circuit or when the Contactor interrupts a circuit
at an extremely low value of the voltage on the
contacts (for example, as rotor circuit Contac-
tors in non-regulated (Irives, etc.).
CONSTRUCTION
The series KTn 500 two-pole Contactors are
based on the design of single-pole D. C. Contac-
tors, series KU 500.
Similar to the series 1Kfl 500 Contactors, all
the parts and assemblies of the Contactor are
mounted on the U-shaped main magnetic yoke,
differing from that of Contactor, series KU 500,
in that the holes are differently located.
Armature, differing from that of the series
KU 500 Contactor, carries a molded plastics
block, to which are fastened two brackets ? the
holders of the flat movable contacts. Such a
fastening ensures reliable insulation between
both contacts and between them and the frame.
The movable contacts and the armature are pi-
voted on prisms. Full symmetry of 1._he movable
contacts of Contactors of the same size allows
the contacts to be turned over in order to use
them again when the upper contact surface is
worn. Contact back-up spring is easily adjusted
and regulated by a shaped bolt, under which it
is possible to place washers. To facilitate the
adjustment of the contact back-up spring, the
bracket has a special slot in which the shaped
bolt moves. The position of the shaped bolt is
fixed by the horn of the movable contact. A flex-
ible lead is fastened to the movable contact. It
connects the contact with the bar terminal.
A molded plastics base is fastened to the main
yoke. The stationary contacts and arc blow-out
device are fastened to the base. The stationary
contact of Contactors for 50-A and 100-A current
ratings is a symmetrical, stamped, clamp-like
part of copper which simultaneously serves as a
contact, an arc blow-out horn and a crown. Such
a design of the stationary contact allows using
it twice, in the same way as the movable contact.
This is attained by turning it through 180? about

the horizontal axis. The stationary contact is
attached to the base with the same screws that
fasten the end of the arc blow-out coil. The other
end of the arc blow-out coil is also the bar termi-
nal of the stationary contact. Contact, arc blow-out
horn and crown of the Contactors for 150 A and
300 A current ratings are in tile form of separate
parts. The arc blow-out chute is put on the horn
of the stationary contact and fastened in place
with a screw.
Contactors, series KTFI 500, in the same man-
ner as Contactors, series KFI 500, arc furnished
with a series arc blow-out assembly for extin-
guishing the electrical arc created when the po-
wer circuit is interrupted by the contacts. The
number of turns of the arc blow-out coil are so-
mewhat decreased to prevent overheating of the
arc blow-out cheeks and the solid core (of the
arc blow-out coil) when 50 c. p. s. A. C. flows in
the main circuit.
TECHNICAL DATA
Main contacts of the Contactors, independently for A. C. power circuit voltages up to 380 V at a
of the voltage of the operating coil, are suitable frequency of 50 c. p. s. and for 220 V D. C.

the duty cycle. When Contactors are installed in
an enclosure, the curr-nt rating in comparison
with the nominal value, as a rule, should be re-
duced in accordance with the type of the enclo-
sure, its volume and the heat liberated by other
equipment located in the same enclosure. Data
concerning allowable ratings of the Contactors
under various operating conditions are given in
the Table.
ting should be lowered, in comparison with the
nominal value in accordance with the data indi-
cated in the Table.
When the Contactors operate under conditions
of intermittent duty, an increase in the current
rating., in comparison with the nominal value, is
allowable only when the number of operations
does not exceed (;00 per hour.
When the Contactor interrupts the load current
the arc is thrown out of the arc blow-out chute
to a distance depending on the character and
value of the current interrupted, the voltage on
the contacts, and the character of the load. To
ensure reliable operation of the series KI1 500
Contactor, the distance from current-carrying to
earthed parts (for example, when installed in an
enclosure ----- the wall of the enclosure is to be
covered with sheet asbestos) schould correspond
to the Table.
