CKF Phase Sequence and Phase Loss Sensor 10A 1Z 3X400V/230V+N AC Surface Mounted

The phase sequence and phase loss sensor is designed to protect electric motors powered from a three-phase network in cases of voltage loss in at least one phase or voltage asymmetry between phases.

Application

With a fixed voltage asymmetry trigger threshold. It protects the direction of motor rotation in case of a phase change before the sensor, which protects the motor from damage.
