The Schneider Electric ENW22305 is a chassis for the EasyPact NW family of air circuit breakers. Drawout mounting means the breaker mechanism slides into a fixed cradle, allowing the moving portion to be racked out for maintenance or isolation without disturbing the line and load connections. This is standard for switchgear where a breaker must be withdrawn for safe inspection or replacement while the bus remains live.
The chassis measures 560 mm deep by 400 mm wide by 440 mm high. These dimensions govern the switchgear cubicle depth and the busbar take-off spacing. The drawout cradle requires a cutout and guide rails in the panel; verify the cubicle depth accommodates the full 560 mm travel plus clearance for the racking handle.
