Eaton B100 Manual Motor Starter

The Eaton B100M0CA is a manual motor starter rated for 45 A at 600 V AC. It uses a NEMA Size M-0 frame with three poles and a push-button operator for direct on-off control of three-phase motors in industrial settings.

For motor circuits up to 5 hp at 480 V or 600 V

This starter suits panels that need simple, local motor control without a magnetic contactor or overload relay. It is not for applications requiring remote operation, automatic overload protection, or control of loads beyond the listed horsepower ratings at 120 V, 208 V, 240 V, 480 V, or 600 V.

45 A continuous current at 600 V AC

The 45 A rating at 600 V AC is the decisive limit for conductor sizing and motor full-load current. If the connected motor draws more than 45 A or the system voltage exceeds 600 V AC, a different starter must be selected.

Questions about this item

How can I verify the B100M0CA is operating correctly after wiring it to a 45 A three-phase load?

Confirm the push-button operator latches firmly in the ON position, the motor starts without tripping, and the measured line current on each of the three poles stays at or below 45 A under full load.

What accessories are included with the B100M0CA and what must be purchased separately?

The starter ships as a complete NEMA Size M-0 unit with built-in push-button operator and three-pole contacts; overload relays, enclosures, mounting hardware and control-circuit wiring are not included.

Which horsepower rating should I use to size the B100M0CA for my 240 V three-phase motor?

At 240 V AC three-phase the starter is rated for 2 hp; choose this rating when the motor nameplate shows 2 hp or less at 240 V three-phase.
