Phase and asymmetry loss relay with contactor control 10A 1Z 4sec 55V CZF-2B
Intended use: The phase loss sensor with contactor control is intended to protect electric motors powered by a three-phase network in cases of voltage loss in at least one phase or voltage asymmetry between the phases.
Operation: Voltage loss in at least one phase or voltage asymmetry between the phases above the activation threshold will shut down the motor. The shutdown will occur with a delay of 4 seconds, which prevents the disconnection of the motor in the event of a momentary voltage drop. Reactivation will occur automatically when the voltage increases by 5 V above the activation voltage. The failure of any contact of the contactor that activates the motor will result in permanent shutdown of the motor. Restarting is only possible after fully disconnecting the power supply, removing the contactor fault, and reconnecting it.
