The ENW22337 is a chassis from the Schneider Electric EasyPact NW range, rated for 2000 A at 40 °C with N breaking capacity across 4 poles. The drawout mounting means the switching element can be racked out for inspection or replacement without disturbing the main bus connections — a standard feature for high-current switchgear where downtime on the bus is not acceptable.
The chassis measures 560 mm deep, 400 mm wide, and 440 mm tall. The drawout mechanism requires the mating cradle and bus connections to be pre-installed in the switchgear cubicle; verify that the existing enclosure depth accommodates the full 560 mm plus clearance for the racking handle travel.
