The ENW22314 is a chassis from the Schneider Electric EasyPact NW range — a drawout-mount, three-pole (3P) low-voltage power breaker chassis rated 2500 A at 40 °C with H breaking capacity. This is the bare chassis (no cradle, no trip unit), intended for mounting inside a switchgear cubicle where the drawout mechanism allows the breaker to be racked out for maintenance without disturbing the bus connections.
Dimensions and physical integration
The chassis measures 445 mm deep, 400 mm wide, and 440 mm high. Those are the envelope dimensions for the chassis alone — the cubicle cutout and racking mechanism need to accommodate the drawout travel plus the arc chamber clearance above and below. When specifying the cradle (the fixed portion that stays in the cabinet), verify the matching frame size; the ENW25H designation on the nameplate ties to a specific cradle footprint. The drawout mounting means the breaker portion slides into a fixed cradle on guide rails, with primary disconnects engaging at the final position.
What the 2500 A rating means for your bus
In a real switchgear lineup, this is the main breaker rating for a 2500 A bus — sized for the transformer secondary or generator output at that level. The H breaking capacity code (not a numeric value in this evidence, but the family designation) places it above the standard N rating for fault interruption. For selectivity studies, the trip unit (ordered separately) sets the long-time, short-time, and instantaneous pickup values; the chassis itself is the current-carrying and interrupting platform.
