The Schneider Electric EZEUVR200AC is an undervoltage release (device short name MN) in the EasyPact range, designed as a control-circuit accessory for EZC250 and EZCV250 circuit breakers. It operates on a 200...240 V AC 50/60 Hz control circuit voltage and triggers opening when the voltage drops to 0.35...0.7 Un, with re-closing possible only after voltage returns to 0.85 Un.
The undervoltage release function (MN) is a safety feature: it trips the breaker when the control voltage falls below 0.35...0.7 Un, protecting downstream equipment from brownout conditions. The 0.85 Un closing threshold ensures the breaker cannot be re-energized until the supply has substantially recovered, preventing partial-voltage starting of motor loads.
Deployment Context
It is a control accessory, not a standalone device — specify it alongside the breaker for coordinated undervoltage protection on pumps, conveyors, or compressor circuits.
