Soft Starters

A complete range of micro- processor based Soft Starters with Output Power Ratings from 1.1kW/1.5HP up to 1850kW/2500HP with standard By-Pass Relay.

Available with internal or external bypass relay, Fieldbus communication, intelligent pump control, optimised motor starting torque, electronic motor protection, etc.

ERSSW series soft starters are static starters designed for the acceleration, deceleration and protection of three phase induction motors. This series is based on microprocessors with state-of-the-art design for the best starting performance and a low cost complete solution.

The control of voltage applied to the motor, by means of thyristor firing angle variation, enables smooth starting and stopping. With proper adjustments it is possible to optimise the motor starting torque so that the starting current remains as low as possible.

3-wire (Star or Delta) and 6-wire (inside Delta) connections to the motor are possible.

Remote HMI with parameter copy function for  mounting in cabinet door or at the front of the soft starter are available.
