What this rear connection does for the EasyPact NW breaker
The ENW33103 is a rear connection accessory for the Schneider Electric EasyPact NW range, designed for 4-pole fixed-mount breakers. It mounts at the top of the breaker with a horizontal connection orientation and a 70 mm pitch between poles, routing power through the rear of the panel instead of the front face.
Rated 630...1600 A, this rear connection handles the full current range of the EasyPact NW frame. That 1600 A ceiling means it's sized for the largest NW breakers in the family — no need to swap the connection kit if you later uprate the breaker within the same frame. The fixed mounting keeps the bus-bar geometry predictable for the panel builder: once the rear connection is bolted down, the breaker position relative to the gland plate is locked.
