The ENW22306 is a Schneider Electric EasyPact NW chassis — the frame that carries the interrupting mechanism for a 2500 A, 4-pole circuit breaker in drawout configuration. Rated 2500 A at 40 °C, it sits inside a switchgear cubicle and is pulled out for maintenance or replacement without disturbing the bus connections. The N breaking capacity code means it is sized for standard distribution duty, not high-fault industrial feeds.
The chassis measures 560 mm deep, 400 mm wide, and 440 mm high. Drawout mounting means the breaker mechanism slides into a fixed cradle; the cubicle door and interlocks are designed around this envelope. Verify the cutout and rail spacing in the switchboard against these dimensions before committing the panel layout.
