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

The phase loss sensor with contactor control is designed to protect electric motors powered by a three-phase network in cases of voltage loss in at least one phase or voltage asymmetry between phases, as well as damage to the contactor contacts that threaten to destroy the motor.

Application

1 x NO non-separated contact. Designed for protecting electric motors.
