DRMS Series Hybrid Motor Starters are intelligent and convenient solutions for controlling 3-phase asynchronous motors. These compact devices can provide up

to 6 functions in the same unit: Forward/Reverse, Soft Start/Soft Stop, Motor Overload Protection, and Mains Isolating Relay.

Motor overload detection is based on a thermal load curve. The relays are de-energized when an overload condition is present, ensuring a long service life.
