What this chassis carries
The ENW22316 is a drawout chassis for the EasyPact NW family, rated 4000 A at 40 °C across three poles with an H breaking capacity code. That H rating means it handles higher prospective fault currents than the standard S or N versions — useful when the transformer or generator feeding the switchboard can deliver a stiff short-circuit. The drawout mechanism lets you rack the breaker out for maintenance or replacement without unbolting power cables, which cuts downtime on a 4000 A bus.
Integration notes
Drawout mounting means the chassis slides into a fixed cradle with primary disconnects — no bolted bus connections on the breaker side. The 445 mm depth and 400 mm width fit standard EasyPact NW switchboard compartments; verify the cradle cutout matches the manufacturer's template before panel layout. The 440 mm height includes the racking mechanism travel.
