What this switch disconnector is rated for
The ENW24284 is a 4-pole switch disconnector in the EasyPact NW range, rated 4000 A in AC-23A utilisation category at 690 V AC — that means it handles motor loads with occasional overloads, not just resistive heating. The short-time withstand rating is 66 kA for 1 s (36 kA for 3 s), and the making capacity hits 143 kA peak. Those numbers tell you it coordinates with upstream protective devices rated for those fault levels — critical when you are specifying the switchgear lineup. Insulation voltage is 1000 V AC, impulse withstand 12 kV, and pollution degree 4 per IEC 60664-1 — that is the harshest industrial environment rating, meaning it is designed for conductive dust or heavy condensation without tracking.
Drawout mounting on a rail, rear-connected, with a 115 mm connection pitch without spreader. The neutral is on the right. Overall dimensions: 556 mm wide, 439 mm high, 395 mm deep. IP40 enclosure protection — suitable for indoor switchgear cubicles, not washdown areas. Mechanical durability is 20,000 cycles with maintenance or 10,000 without; electrical durability for AC-23A duty is 5000 cycles at 440 V and 2500 cycles at 690 V.
