The ENW33104 is a rear connection accessory for the Schneider Electric EasyPact NW range of air circuit breakers. It is a 4-pole drawout version, mounted at the top of the breaker, with a horizontal connection orientation and a 70 mm pitch between phases. The rated current range of 630 to 1600 A tells you the breaker frame sizes this accessory mates with — not the continuous load of the accessory itself, but the breaker it connects.
Drawout mounting — what it means on the switchboard floor
Drawout mounting means the breaker slides into a cradle; the rear connection stays fixed to the switchboard. For a panel OEM or site electrical engineer, this is the part that stays bolted to the busbars while the breaker itself racks in and out for maintenance or swap. The 70 mm pitch matches the standard EasyPact NW cradle footprint — no adapter plate needed. Top-mount, rear-connection orientation means the power cables enter from above and terminate behind the breaker, which keeps the front of the cubicle clear for the control wiring and the breaker mechanism.
