All Class A200 non-reversing starters contain block Type B three-pole overload relays with three current transformers. A200 sizes 5 and 6 starters contain an AC magnetically operated size 5 or 6 line contactors, and size 6 starters include a control relay with contacts to handle the coil current. Size 7, 8 and 9 starters contain a DC operated line contactor, DC power supply, and a control relay. All Class A200 starters are UL listed and recognized and are CSA certified.
A200 Series Solenoids
Starters—Non-Reversing and Reversing
NEMA Sizes 00–4; Three-Phase,
1-1/2–100 hp
These Starters from Eaton’s Electrical Sector use Class A201 contactors. Contactor features are enhanced through the ability to provide positive motor protection in the form of several types of overloadrelays.
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 standard. 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 conversion 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.
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 woundrotor motors.
For plugging or inching, when operations exceed five times per minute, decreased horsepower ratings in accordance with NEMA Standard ICS-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 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 three-pole and one five-pole starter mechanically and electrically interlocked.
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 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 starters use Class A201 contactors. 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.
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 protection 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
Application Description
