EasyPact NW coil for MX/XF/MCH releases
The Schneider Electric ENW21545 is a fixed-mount coil for the EasyPact NW range, designed to drive MX shunt trip, XF closing, or MCH undervoltage releases on NW-frame air circuit breakers and switch-disconnectors. Control voltage is 100/125 V DC, maintained signal type, electrically operated — so it holds the release in the commanded state as long as the DC control voltage is present.
What the control voltage means for fit
100/125 V DC is a common station-battery voltage in industrial and utility switchgear — the coil is sized for that nominal range. The maintained control signal type means the coil stays energised to hold the release in its operated position; remove the DC signal and the release resets.
