The Schneider Electric ENW24226 is a fixed-mount switch disconnector from the EasyPact NW range, rated 2500 A in AC-23A duty at 690 V AC, 50/60 Hz. That AC-23A utilisation category means it is designed for switching motor loads and other highly inductive circuits — not just resistive isolation — and it carries a making capacity of 143 kA peak and a short-time withstand of 66 kA for 1 second per IEC 60947-3. The 4-pole configuration with neutral on the left suits distribution panels where a switched neutral is required, and the rear connection with a 115 mm pitch (without spreader) determines the busbar layout.
The 2500 A continuous rating at 690 V is the headline number, but the AC-23A electrical endurance figures tell the real story for motor-switching applications: 5000 cycles at 440 V without maintenance, dropping to 2500 cycles at 690 V. If your duty cycle exceeds that, you will need to schedule maintenance or upsize. The mechanical durability is 20000 cycles with maintenance, 10000 without — both per IEC 60947-3. The HA breaking capacity code indicates a high interrupting rating, and the rated short-time withstand current of 66 kA for 1 second (36 kA for 3 seconds) gives the selectivity engineer headroom for coordination studies in high-fault-current panels. Pollution degree 4 per IEC 60664-1 is the most severe industrial classification — conductive dust or moisture bridging is expected. This switch disconnector is rated for that environment without derating, which is unusual for a device this size. The IP40 enclosure protection means it is not washdown-rated; it belongs in a clean, dry cabinet. Isolation suitability is confirmed per IEC 60947-3, with a visible contact position indicator. The rated insulation voltage is 1000 V AC, and impulse withstand is 12 kV.
Fixed mounting on a base plate — no DIN rail. The dimensions are 537 mm wide by 352 mm high by 297 mm deep, so the enclosure must accommodate those clearances plus the rear connection depth. The connection pitch of 115 mm without spreader sets the busbar drilling pattern. Horizontal or vertical connection orientation is permitted, giving layout flexibility in the cabinet.
