CZF-2 Phase Loss Sensor 10A 1Z 3X400/230V+N AC with Contactor Control

Phase loss sensor with contactor control, designed to protect electric motors powered from a three-phase network. Used in cases of voltage loss in at least one phase and voltage asymmetry between phases.

Application

Sensor with a fixed voltage asymmetry threshold, protecting against motor damage. Ideal for monitoring the power supply status and the functioning of the contactor.
