The ENW24106 is a 3-pole EasyPact NW circuit breaker rated 2500 A at 40 °C, with a breaking capacity of 50 kA Icu at 220…440 V AC 50/60 Hz conforming to IEC 60947-2. At 690 V the Icu drops to 42 kA, still sufficient for most industrial secondary distribution. The drawout mounting means the breaker chassis slides into a fixed cradle, allowing safe isolation and replacement without unbolting busbars — standard for switchgear lineups where maintenance access matters. Rated insulation voltage (Ui) is 1000 V AC, and the impulse withstand (Uimp) is 12 kV, confirming the part is designed for systems where transient overvoltages are a concern — typical in industrial environments with motor starts and capacitor switching.
Deployment context
This breaker is a drawout unit designed for mounting on a rail in low-voltage switchgear assemblies. The rear connection position with a 115 mm pitch without spreader matches standard busbar take-off spacing in common switchgear cubicles.
Key approvals and standards
Certified to IEC 60947-2 for low-voltage switchgear and controlgear. Suitability for isolation means it can be used as a disconnecting means per code. Electrical durability is 5000 cycles at 440 V and 2500 cycles at 690 V without maintenance; mechanical durability is 20000 cycles with maintenance, 10000 without. These figures guide preventive maintenance scheduling — plan inspection at the 5000-cycle mark for typical 440 V distribution.
