What this rear connection does in the cell
The ENW33108 is a rear connection accessory for the EasyPact NW family of drawout air circuit breakers, configured for 4-pole (4P) systems rated 630 to 1600 A. It mounts at the bottom of the breaker cradle and connects horizontally to the busbars through a 70 mm pitch interface.
The 630...1600 A rated current range covers the full EasyPact NW drawout breaker line from NW08 through NW16. The 70 mm connection pitch is standard for this frame size — it matches the busbar spacing on the cradle's rear terminals, so the accessory aligns without adapter plates. Drawout mounting means the connection stays fixed to the cradle while the breaker racking mechanism inserts and extracts the moving portion; the rear connection does not travel with the breaker body.
This is a bottom-mounted, horizontal rear connection — it occupies the lower portion of the drawout cradle behind the breaker. The 4-pole configuration handles three phases plus neutral (or a fourth pole for alternate distribution schemes). Because it is a connection accessory rather than a breaker, it ships as a separate kit; the installer bolts it to the cradle's rear busbar stabs before racking the breaker in. The 70 mm pitch matches standard EasyPact NW busbar drilling patterns, so no field modification of the busbar is required.
