Eaton B100 Manual Motor Starter
The Eaton B100 manual motor starter is a three-pole toggle switch rated at 5 A for industrial motor control. It handles single-phase loads up to 2 hp at 120 V and 3 hp at 240 V. Three-phase ratings reach 2 hp at 208 V and 240 V, and 5 hp at 480 V and 600 V. Designed for NEMA size M-0 applications.
Toggle Operator and Three-Pole Build
A front-mounted toggle operator provides direct on-off control for three-phase circuits. The transparent housing allows visual confirmation of contact position during routine checks. Three-pole construction switches all lines simultaneously for balanced motor protection. Rated for a maximum of 600 V AC across industrial power systems.
Verify Voltage Phase and Current Before Ordering
Confirm the supply voltage matches one of the rated levels: 120 V, 208 V, 240 V, 480 V or 600 V AC. Ensure the motor full-load current does not exceed 5 A for the chosen voltage and phase. The starter has no adjustable overload relay, so external overload protection must be provided separately. Not suitable for loads requiring higher current settings or different pole counts.

Questions about this item
What does the 600V AC maximum voltage rating cap in practice?
The 600V AC maximum rating means the starter can be applied on three-phase systems up to 600V, covering 208V, 240V and 480V motor circuits without exceeding its insulation or contact ratings.
What physical space and mounting does the NEMA M-0 3-pole toggle unit need?
The NEMA M-0 frame fits standard NEMA starter enclosures and panels; the 3-pole toggle operator requires a cut-out for the handle and enough depth for the contact block behind the mounting surface.
How is the B100 series starter wired and what step is often missed?
Connect three-phase supply to the line terminals and motor leads to the load terminals; the step often missed is verifying the toggle moves freely to the OFF position before energising the circuit.
