Description

The MCB Under Voltage Release is an essential accessory designed specifically for use with DAB7 (63 frame) circuit breakers. This device effectively monitors and controls circuit conditions by disconnecting the power supply when the voltage falls between 70% and 35% of the rated voltage (Ue). It ensures safe operation by preventing the circuit breaker from closing when the voltage is below 35% Ue and allows reconnection when the voltage is restored to levels between 85% and 110% Ue. Engineered for reliability and precision, the MCB Under Voltage Release is ideal for various electrical applications.
