The undervoltage release (UVR) as part of the remote tripping is used with EasyPact c circuit breakers. This undervoltage release is operated with 200-277V AC 50/60Hz voltage (Un). The tripping threshold is between 0.35 and 0.7 times the associated voltage. This release trips the circuit breaker when the control voltage drops below the tripping threshold. The circuit breaker can only be switched on if the voltage exceeds 0.85 times the associated voltage. The installation is an outdoor installation.
