CZF-B PHASE LOSS AND ASYMMETRY SENSOR 10A 1Z 2M 3X400/230V+N AC

Phase loss sensor that protects electric motors from damage due to voltage loss or asymmetry in three phases.

Application

Designed to protect electric motors in a three-phase network. It is effective in situations where one of the phases is lost or there is voltage asymmetry, which may threaten the motor’s integrity.
