Phase loss relay F&F CZF-TRMS 10A 1NO delay 4s asymmetry 45V True RMS. The relay is designed to protect an electric motor powered by a three-phase network in cases of voltage loss in at least one phase or voltage asymmetry between the phases.

Function:

• The voltage loss in at least one phase or the voltage asymmetry between the phases above the activation threshold will turn off the motor.
• The shutdown will occur with a 4-second delay, preventing the accidental disconnection of the motor during momentary voltage drops.
• It will automatically reactivate when the voltage increases by 5 V above the activation voltage.
• The sensor measures the actual voltage value (True RMS) for correct operation in networks with large disturbances.
