Sizes 00 – 4
Application
Magnetic starters are used for fullvoltage, across-the-line starting and
stopping of squirrel cage motors. They
can be operated locally or remotely by
manual or automatic pilot devices.
NEMA Sizes 00 – 4;
Three-Phase, 1-1/2 – 100 hp
These Cutler-Hammer® Starters from
Eaton’s electrical business use Class
A201 contactors as described on
Page 2. Contactor features are
enhanced through the ability to provide positive motor protection in the
form of several types of overload
relays. See Pages 28 – 36.
Type B Overload Relay, Manual Reset Only
Supplied as standard on Class A200
and A900 starters (two-speed). The bimetallic overload relay offers ambient
compensation and trip-to-test feature
(relay contact status check) as standard. In addition, an isolated normallyopen contact is available in kit form for
customer mounting. Type B overload
relays are manual reset only.
Type A Overload Relay, Manual
or Automatic Reset
This is an optional overload relay,
offering the capability of field conversion to automatic reset. It is available
as an ambient compensated or noncompensated type.
Non-reversing Starters
Non-reversing starters are supplied as
open devices. All starters are supplied
with a normally-open holding circuit
interlock.
Class A200 starters are available as UL
listed or recognized components, as
well as with CSA certification.
Reversing Starters
For reversing applications (Class
A210), a starter and a contactor electrically and mechanically interlocked are
supplied on a common baseplate.
Reversing starters are used to start,
stop and reverse AC squirrel cage
motors and for primary control of
reversing wound-rotor motors.
For plugging or inching, when operations exceed five times per minute,
decreased horsepower ratings in
accordance with NEMA Standard ICS
2-321 are recommended.
Two-Speed Starters, A900s
For across-the-line starting of twospeed constant hp, constant torque
and variable torque squirrel cage
motors, two-speed starters (Class A900)
are available. These Cutler-Hammer
starters consist of two starters, one for
each motor speed, mechanically and
electrically interlocked and wired for
manual speed selection by means of
pushbuttons. Auxiliary relays may be
added to provide automatic acceleration or deceleration.
Starters for two-speed, two independent winding motors consist of two-,
three- or four-pole starters electrically
and mechanically interlocked. Starters
for two-speed, single reconnectable
winding motors consist of one threepole and one five-pole starter mechanically and electrically interlocked.
Size 5 Starter
Product Description —
Sizes 5 – 9
NEMA Sizes 5 – 9;
Three-Phase 75 to 1600 hp
Non-reversing (Class A200), and
reversing (Classes A210, A250) full
voltage starters are used for acrossthe-line starting of squirrel cage induction motors. They are used with
motors rated above 50 hp at 230V, and
above 100 hp at 460 through 600V.
Sizes 5 and 6 Cutler-Hammer starters
use Class A201 contactors as described
on Page 3. In addition to standard
motor starters, special application
devices are available: Sizes 5 and 6
starters with integrally rectified AC to
DC coils for applications where low
voltage problems are prevalent are
available.
Class A200 starters are UL listed
and recognized and also carry CSA
certification.
Front Removable Parts — All operating parts can be removed quickly and
easily from the front. Straight-through
wiring and conveniently located connection points for external wires and
cables minimize installation time.
Type B Block Type Thermal Overload
Relay — Dependable overload protec-
tion is assured by these snap-action,
manual reset relays. Automatic reset
Type A relays are available as an
option.

Types of Starters
Class A200, Sizes 5 and 6 — Non-
reversing starters contain an AC
magnetically-operated Size 5 or Size 6
line contactor and block Type B three-
pole overload relay, along with three
current transformers. A control relay
whose contacts handle the coil current
of the starter is provided with Size 6
starters.
Class A200, Sizes 7, 8 and 9 — Non-
reversing starters contain a DC
operated line contactor, DC power sup-
ply, block Type B three-pole overload
relay with three current transformers
and a control relay.
Class A960/A970/A980 Multi-Speed
Starters: Refer to Page 15.
