The ENW24249 is a 4-pole EasyPact NW drawout circuit breaker rated 2000 A at 40 °C. That 2000 A continuous current makes it a main or heavy feeder breaker for large distribution switchboards — think plant incoming supply or a big motor control center bus. At 690 V the Icu drops to 50 kA, so if your system runs at 690 V, coordination studies need that lower figure. That's a Category B utilization characteristic: the breaker is intended for selective coordination with downstream devices, not just cable protection.
The ENW24249 is listed as current production within the EasyPact NW range. That means it's still a standard catalog item, not a phase-out or last-time-buy part.
Integration notes
Drawout mounting on a rail means the breaker slides into a cradle — you can rack it out for maintenance or replacement without disconnecting the main power cables. The rear connection position with vertical or horizontal orientation suits rear-accessible switchgear lineups. Physical footprint: 556 mm wide, 439 mm high, 395 mm deep. The 115 mm connection pitch without spreader matters for busbar drilling patterns.
Designed and tested to IEC 60947-2 for low-voltage switchgear and controlgear. Suitability for isolation is confirmed — important for a visible-break isolation point in a maintenance lockout procedure. The electrical durability figures give 6000 cycles at 440 V and 4000 cycles at 690 V without maintenance; mechanical durability is 20000 cycles with maintenance, 10000 without. These numbers drive the inspection interval in a preventive maintenance schedule.
