The smart motorstarter UG 9256/804 and UG 9256/807 is used to provide always a clockwise phase sequence and to start asynchronous motors. Independent of the the pase sequence on the input it will always provide clockwise sequence on the output to the motor. The unit also protects the motor against phase failure and motor overload. The relays of the reversing circuit switch without current. This provides a long electrical life.
