The Schneider Electric EZEUVR125DC is an undervoltage release (device short name MN) for the EasyPact EZC250 and EZCV250 molded-case circuit breaker ranges. It drops the breaker when the control voltage falls below 0.35 to 0.7 Un and allows closing only when voltage returns above 0.85 Un — a standard undervoltage protection function for control circuits that need to prevent automatic reclosure after a dip or outage.
Control voltage and fit
Rated for a 125 V DC control circuit. The operating threshold is specified as 0.35...0.7 Un for opening and 0.85 Un for closing, so on a 125 V DC system the release trips when the voltage drops to roughly 44–88 V DC and resets above about 106 V DC. It mounts inside the EZC250 or EZCV250 breaker — no separate DIN-rail space needed, but the breaker itself occupies the panel cutout.
