Chassis for 4000 A Drawout Power Breaker
The Schneider Electric ENW22332 is a chassis for the EasyPact NW family, rated for a 4000 A drawout power circuit breaker at 40 °C ambient. The N breaking capacity code indicates the interrupting rating tier for this frame size — coordination studies should reference the breaker's specific N-level let-through curves. Drawout mounting means the breaker mechanism slides into this chassis on rails, allowing the moving portion to be racked out for maintenance or replacement without disturbing the line and load connections.
The chassis measures 445 mm deep by 400 mm wide by 440 mm high. For a retrofit into an existing switchgear lineup, verify that the enclosure cutout and bus-bar alignment match these dimensions — the drawout mechanism requires clearance at the rear for the racking travel and at the front for the breaker cradle. The 3-pole configuration (3P) is standard for three-phase power distribution.
