The ENW33113 is a rear connection accessory for the Schneider Electric EasyPact NW range of air circuit breakers. It is a 3-pole fixed-mount connection kit rated for 630 to 1250 A, designed for bottom mounting on the breaker.
The 630...1250 A current range means this rear connection covers the full span of EasyPact NW frame sizes from the NW08 up through NW12. If your BOM calls for a 630 A or 1250 A breaker, this single accessory part fits both — no need to order by frame ampacity. The fixed mounting mode means the connection is intended for stationary, non-drawout breaker installations. The 70 mm connection pitch tells you the busbar or cable lug spacing it mates to.
Where this class of part is used
Rear connection kits like this one are used in switchboard and motor control center (MCC) builds where the EasyPact NW breaker is mounted fixed — typically in main distribution panels, generator incomers, or large feeder applications. The bottom-mount orientation suits vertical busbar runs in floor-standing enclosures.
