Sensor for phase loss and asymmetry CZF-333 Un = 3 × 400V Io <10A mounting on TH-35 rail actuation voltage adjustment reacts to symmetrical and asymmetrical voltage drop

The CZF-333 phase loss sensor is designed to protect an electric motor powered from a three-phase network in the event of a voltage failure in at least one phase, symmetrical voltage drop in three phases or voltage asymmetry between phases, with the risk of damaging the motor.
