EasyPact ENW225H3MW6SVG — 2500 A Drawout Breaker with LSIG Trip
The Schneider Electric ENW225H3MW6SVG is a 3-pole drawout circuit breaker from the EasyPact range, rated at 2500 A continuous (at 50 °C) with a breaking capacity of 66 kA Icu at 220...440 V AC 50/60 Hz per IEC 60947-2. It carries the Trip System 6.0s electronic trip unit with LSIG protection — long-time, short-time, instantaneous, and earth-fault — making it a Category B breaker suited for distribution in main switchboards.
For a distribution board fed from a transformer in the 2–3 MVA range, that SCCR headroom covers most industrial service-entrance faults without cascading upstream. The LSIG trip unit gives you four independent protection curves: long-time (overload), short-time (selective coordination with downstream breakers), instantaneous (fast clearing for high faults), and earth-fault (ground leakage). The 2500 A CT rating matches the breaker frame, and the current sensor range spans 1000/4000 A, so the same frame can be re-rated downward if needed. Rated insulation voltage (Ui) is 1000 V AC — the breaker is electrically safe at that voltage level, though the operating network here is 440 V.
Drawout mounting on a base plate or rail — the breaker chassis slides in and out for maintenance without disturbing the rear-connected power cables. Connection pitch is 115 mm without spreader; vertical or horizontal rear connection gives flexibility in cabinet layout. IP40 protection means it's enclosed against tools and small objects, not washdown. Electrical durability at 440 V AC is 5,000 cycles Category B without maintenance — that's the number to watch for a breaker that sees frequent switching, not just fault protection.
