The Schneider Electric ENW23303 is a chassis for the EasyPact NW range of air circuit breakers, configured as a 4-pole unit rated 1000 A at 40 °C. It carries breaking capacity code C, meaning it is sized for standard distribution-level fault interruption within the EasyPact NW family. The drawout mounting means the breaker mechanism slides into a fixed cradle — the chassis stays wired to the busbars while the moving portion can be racked out for maintenance or replacement without disturbing the power connections.
The chassis measures 358 mm wide by 322 mm high by 277 mm deep. These dimensions govern the cutout and mounting footprint in the switchgear lineup. The drawout design requires the fixed cradle to be bolted into the enclosure and the bus connections made to the rear terminals; the breaker unit itself then slides in and engages the primary disconnects. Panel builders should verify the depth clearance behind the mounting plate — 277 mm plus space for the rear bus connections and any arc chute exhaust path.
