Sizes 00 – 4
General
Magnetic starters are used for full-
voltage, 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 starters use Class A201 contac-
tors as described on Page 33-115.
Contactor features are enhanced
through the ability to provide positive
motor protection in the form of several
types of overload relays. See Pages
33-141 – 33-149.
Type B Overload Relay, Manual Reset Only
Supplied as standard on Class A200
and A900 starters (two-speed). The bi-
metallic overload relay offers ambient
compensation and trip-to-test feature
(relay contact status check) as stan-
dard. In addition, an isolated normally-
open 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 conver-
sion to automatic reset. It is available
as an ambient compensated or non-
compensated 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 electri-
cally 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 opera-
tions 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 two-
speed constant hp, constant torque
and variable torque squirrel cage
motors, two-speed starters (Class
A900) are available. These starters
consist of two starters, one for each
motor speed, mechanically and electri-
cally interlocked and wired for manual
speed selection by means of pushbut-
tons. Auxiliary relays may be added to
provide automatic acceleration or
deceleration.
Starters for two-speed, two indepen-
dent 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 three-
pole and one five-pole starter mechan-
ically 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 across-
the-line starting of squirrel cage induc-
tion motors. They are used with
motors rated above 50 hp at 230V, and
above 100 hp at 460 through 600V.
Sizes 5 and 6 starters use Class A201
contactors as described on Page 33-
116. 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 operat-
ing parts can be removed quickly and
easily from the front. Straight-through
wiring and conveniently located con-
nection 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.
