This is the drawout version — the breaker mechanism slides into the cradle, so you can rack it out for maintenance without pulling the line-side cables. That's a key difference from the fixed-mount variants: drawout means you can isolate and swap the moving part while the bus stays live, which matters in a switchgear lineup where downtime costs per minute.
The N breaking capacity code tells you the interrupting rating level within the EasyPact NW family; it's the middle tier, not the highest (H) or the standard (S).
Physical integration
Dimensions are 445 mm deep, 400 mm wide, 440 mm high. That's a full-size chassis for a low-voltage power breaker — plan for a dedicated compartment in the switchgear lineup, not a crowded panel. The drawout mechanism means the cradle needs clearance for the racking handle travel.
