The ENW21814 is a closing voltage release for Schneider Electric's EasyPact NW drawout circuit breakers, designated as the XF variant for control applications. It operates on a 220...250 V AC/DC control circuit at 50/60 Hz, drawing 4.5 W holding power once the coil seals in. The operating threshold spans 0.85 to 1.1 Un, meaning the release picks up reliably at 85 % of nominal voltage and holds through a 10 % overvoltage — useful for installations with marginal supply regulation or long control-wire runs that drop voltage under load.
Mounts inside the drawout breaker cradle — no DIN-rail or panel footprint of its own. The 4.5 W holding power is low enough that a standard 24 V DC control transformer with a 100 VA rating can power several releases on the same bus without derating. The 220-250 V AC/DC control voltage covers both common plant control voltages; if your panel runs 230 V AC control, this release drops in without an intermediate relay.
