Eaton B100W1B Non-Reversing Manual Starter

The Eaton NSB B100W1B functions as a dedicated non-reversing manual starter specifically engineered for controlling motor loads within heavy-duty industrial environments where simple engagement and isolation are the primary operational needs.

This unit features a NEMA B100 frame design capable of switching 2-pole circuits at 240 volts AC, making it suitable for single-phase power distribution networks that require direct on-line control of motors rated up to 3 horsepower under standard voltage conditions.

With an adjustable ampere trip setting ranging from 9 to 45 amps, technicians can configure the overload protection elements to match the specific nameplate requirements of connected equipment while maintaining compliance with relevant national electrical code standards for continuous duty operation and thermal overload prevention.

The robust mechanical construction prevents accidental actuation during maintenance activities and allows the device to serve effectively as both a switch and a protective controller in fixed installations such as HVAC units, wastewater pumps, and factory automation processing lines.
