The Schneider Electric ENW24187 is a 4-pole switch disconnector from the EasyPact NW range, rated for 3200 A in AC-23A duty at 690 V AC. It's certified as a disconnector (isolator) per IEC 60947-3, so it provides visible-break isolation for a feeder or distribution panel.
Rated operational current of 3200 A in AC-23A at 690 V. This governs motor feeder applications. Short-time withstand (Icw) is 50 kA for 1 second or 25 kA for 3 seconds — that tells you the switch can ride through a fault until an upstream breaker clears it, without welding shut or exploding. The making capacity of 105 kA peak confirms it can close onto a bolted fault and survive. Rated insulation voltage (Ui) of 1000 V AC and impulse withstand (Uimp) of 12 kV give headroom for 690 V systems and cover surge coordination in industrial networks. IP40 protection means it's splash-proof from tools and fingers but not water jets — install inside a panel or enclosure.
Mechanical and electrical endurance
Electrical durability is 5000 cycles at 440 V and 2500 cycles at 690 V under AC-23A without maintenance — that's the contact wear life. Mechanical durability is 20000 cycles with maintenance, 10000 without. For a drawout switch at this current level, those numbers are typical for a main feeder disconnector that sees infrequent operation.
