The ENW22319 is a chassis from the Schneider Electric EasyPact NW range, rated 1250 A at 40 °C with H breaking capacity code, configured for 4-pole drawout mounting. This is the bare chassis — the moving part that carries the main contacts and arc chute, designed to slide into a fixed cradle for service without unbolting busbars.
Drawout mounting means the chassis pulls out for inspection or swap without disturbing the fixed cradle's power wiring — a real time-saver during a line-down event.
Physical integration
Dimensions: 560 mm deep, 400 mm wide, 440 mm high. That depth is the key clearance number for the enclosure — the drawout mechanism needs travel space in front of the cradle. Standard 600 mm deep switchgear cubicles accommodate it, but verify the door swing and racking clearance before cutting the panel.
