  • Product colorTransparent
  • Handles three-phase loads up to 600 V AC
  • Push-button operator gives direct local control
  • Rated 5 A for motor branch-circuit protection
  • NEMA size M-1 suits compact panel layouts

Industrial Motor Starter

The Eaton B100S1CA is a manual motor starter built for three-phase industrial control panels. Rated at 5 A with a 600 V AC maximum, it suits motor loads up to 10 hp at 480 V or 600 V three-phase and 7 1/2 hp at 240 V single-phase. The push-button operator provides direct local start and stop control without a separate contactor.

Panel Integration

The unit mounts in a standard NEMA Size M-1 enclosure and uses three poles for three-phase circuits. Its 5 A rating means the branch circuit protection and conductor sizing must match this current value. The transparent cover allows visual confirmation of contact position while the starter remains energised, reducing troubleshooting time during commissioning.

Upgrade Path

This starter replaces smaller fractional-horsepower starters when motor loads grow beyond their contact rating. The jump is worth it when a machine moves to a 10 hp three-phase motor at 480 V or 600 V, or when a single-phase load reaches 7 1/2 hp at 240 V. It does not serve applications requiring adjustable overload relay settings or magnetic contactor-based remote control schemes.

Questions about this item

Will the 5 A rating hold continuously on a 600 V three-phase motor?

It is rated for 5 A AC with a maximum voltage of 600 V AC on three-phase supplies.

How much heat or noise does the push-button starter produce during all-day operation?

The unit has no fan and no moving parts except the push-button contacts, so it runs silently and generates minimal heat.

What supply voltage and control wiring must already be in place to install this starter?

You need a three-phase supply up to 600 V AC and a control circuit wired to the push-button operator.
