What this 2000 A EasyPact NW breaker is for
It carries a 50 kA Icu at 220–440 V AC and 42 kA Icu at 690 V AC per IEC 60947-2, so it handles high-fault utility feeds without cascading upstream. The 1000 V rated insulation voltage (Ui) and 690 V operational voltage (Ue) cover standard 400/480 V and 690 V plant networks.
The ENW24129's breaking capacity code is N, with a symmetrical Icu of 50 kA at 440 V and 42 kA at 690 V. The Ics (service breaking capacity) matches those same figures, so the breaker can reclose after a fault at full rated voltage without derating — important for selectivity studies in a distribution board. Maximum breaking time is 25 ms, and maximum closing response time is 70 ms, giving a fast enough clearing for downstream coordination with MCCBs and fuses. Category B utilisation means it's designed for distribution with no intentional short-time delay; if you need selectivity with a deliberate delay, verify the trip unit settings against the downstream devices.
Fixed-mount base plate installation, rear vertical or horizontal connection positions. The 115 mm connection pitch without spreader matches standard busbar riser spacing in LV switchgear. Neutral position is left, and the 4-pole protected poles description is 4P 4d — all four poles are protected. Dimensions: 537 mm wide × 352 mm high × 297 mm deep.
