The ENW22327 is a drawout chassis from the EasyPact NW range, rated 1250 A at 40 °C with N breaking capacity and three poles. It is the mounting frame that receives the EasyPact NW circuit breaker — the drawout mechanism lets you isolate the breaker for maintenance or replacement without disturbing the bus connections. In a low-voltage switchgear lineup, this chassis stays fixed in the cubicle while the breaker unit slides in and out.
For a cold-storage or food-processing facility, that rating holds at 40 °C ambient; if your switchroom runs hotter, you derate per the manufacturer's curve. The N breaking capacity code tells you the breaker inserted here is sized for standard-duty fault interruption, not high-fault applications.
Drawout mounting for service continuity
Drawout mounting means the chassis has fixed primary disconnects and a shutter mechanism — the breaker racked in connects the load; racked out isolates it with visible gap. This is standard for main and tie feeders where uptime matters: you can rack out a breaker for inspection or swap without de-energizing the bus. The 445 mm depth, 400 mm width, and 440 mm height fit standard low-voltage switchgear cubicle compartments, typically with rear-access for cable termination.
