Product details

The Schneider Electric ENW24122 is a 4-pole drawout circuit breaker from the EasyPact NW range, rated 2500 A at 40 °C and built to IEC 60947-2 for distribution duty. Pollution degree 4 per IEC 60664-1 confirms it tolerates conductive contamination, so it suits industrial environments where dust or humidity is present.

Drawout mounting on a rail with rear horizontal or vertical connection positions. The 115 mm connection pitch without spreader governs busbar or cable-lug layout. Ambient operating range is -5 to 60 °C; storage from -40 to 85 °C without control unit, -25 to 85 °C with it.

Electrical durability at 440 V AC is 5,000 cycles Category B without maintenance; at 690 V it drops to 2,500 cycles — the higher voltage accelerates contact wear. Maximum breaking time is 25 ms, closing response 70 ms, which sets the coordination window for downstream selectivity.
