DOLD Smart Motor Starter UG 9256

Product description

The smart motorstarter UG 9256 from the MINISTART series is a softstart, reversal and protection of 3-phase asynchronous motors. Overcurrent is detected when the set current is exceeded longer than 2 sec. Direction reversal takes place via relay switching. The relays are de-energised at this. This ensures a long service life.
