A200
Contactors — Non-reversing and Reversing
Size 5 Contactor
Product Description —
Sizes 5 – 9
Class A201, Contactors, Sizes 5 – 9;
Three-Phase, Over 100 hp
These Cutler-Hammer
®
AC magnetic
contactors utilize clapper design and
feature straight-through wiring.
Contacts are silver alloy for longer life.
The contacts close with optimum
wiping action which serves to keep the
contacting surfaces clean. De-ion
®
arc
quenchers draw the arc away from the
contacts at opening, which reduces
burning and pitting and increases
contact life.
All of the contactors are complete with
one unwired, normally-open (NO) auxil-
iary contact mounted and have accom-
modations for additional auxiliary
contacts. No control circuit wiring or
terminal markings are included.
Size 5, 300A, 600V, Open
Size 6, 600A, 600V, Open
Cutler-Hammer Class A201 Size 5 and
6 contactors are front clapper design,
AC operated with the armature pivot-
ing on dual needle bearings which
assure accurate contact alignment.
The contactor base is molded of a
high impact, non-tracking, non-
hygroscopic glass polyester material
permitting front mounting and wiring
on a steel panel.
Floating magnet assures quiet
operation.
Size 5 and 6 contactors must be
mounted with the line terminals
directly above the load terminals.
Multi-voltage coil ratings allow selec-
tion of the voltage which closely
matches the actual system voltage to
assure optimum contactor operation.
Each contactor accommodates two
Type J11 auxiliary contacts, providing
up to four auxiliary circuits,
normally-open or normally-closed
(NO and NC).
A201 Size 5 and 6 contactors and start-
ers are UL recognized when supplied
without terminals. When supplied with
terminals, the devices are UL listed.
Two special configurations of the
Class A201 Size 5 and 6 contactors
are available:
■ Latched Design — This is a mechani-
cally held, electrically released
device. It is applied where the con-
tactor must remain closed during
extreme voltage fluctuations or
power failure. It is also suitable for
applications requiring quiet opera-
tion since the operating coil is de-
energized when the contactor is
closed. The latch assembly consists
of a mechanical latch mechanism,
electrically operated AC trip sole-
noid and a clearing contact.
■ DC Operated — This device is DC
operated. It is used where low drop-
out voltage or exceptionally quiet
operation is desired. The DC assem-
bly consists of a DC operating coil,
integrally mounted rectifier and
shorting contact.
Size 7, 900A, 600V, Open
Size 8, 1350A, 600V, Open
Size 9, 2500A, 600V, Open
Cutler-Hammer Class A201 Size 7 and
8 contactors are DC operated side
clapper design with the shaft mounted
on dual needle bearings to ensure
positive contact alignment and long
contact life.
A steel panel base permits mounting on
angle or channel without additional sup-
port, for versatile low cost installation.
Each stationary contact assembly is
mounted on an individual molded
insulator. Each pair of contacts is sur-
rounded by a De-ion
grid type arc
quencher for rapid and confined arc
interruption and long contact life.
The shunt for each pole is made of
flexible, braided copper cable for free-
dom of movement and long life.
The rugged DC operating coils are
designed to operate at high temperature
and insulated to meet Class H service.
An integrally mounted avalanche type
silicon rectifier supplies DC coil volt-
age from the AC control circuit.
Sizes 7 and 8 accommodate three
Type L-63 auxiliary contacts which are
easily converted from normally-open
to normally-closed, providing auxiliary
circuit flexibility. Size 9 uses L-64
auxiliary contacts with a total of four
circuits.
A201 Size 7, 8 and 9 contactors and
starters are UL recognized when
supplied without terminals. When
supplied with terminals, the devices
are UL listed.
