Phase loss sensor with contact control CZF-2BR contacts: 1NO, I = 10A, adjustable threshold: 165-180V, 2 modules

Phase imbalance decay relay with contactor contact monitoring.
Application:
is designed to protect electric motors supplied from a three-phase network in the event of voltage failure in at least one phase or voltage asymmetry between phases, and damage to the contacts of the switching contactor, with the risk of damaging the motor.
