Benshaw RSM6-50-575-C Soft Start Motor Controller

RSM6-50-575-C is a 50 HP soft-start motor controller from Benshaw, part of the RediStart Micro II family, designed for low-voltage, three-phase motors in the 575 VAC class. It delivers a controlled ramp to running speed to limit inrush current and reduce mechanical stress during startup, with an adjustable initial current commonly set from 50% to 175% of full-load current. As a RediStart Micro II soft starter, the RSM6-50-575-C combines solid-state switching with programmable ramp profiles and motor-protection features to help safeguard the motor and electrical system during start and stop cycles. This model is described in Benshaw’s RSM6 family documentation, which covers soft-start operation and startup parameter customization. Typical applications include any equipment where controlled motor start is desired to minimize voltage dips, electrical noise, and wear on motor windings and drive components.
