Switch disconnector, 1600 A, 3 poles — fixed-mount isolation for distribution
The ENW13277 is a fixed-mount switch disconnector from the EasyPact NW range, rated 1600 A in AC-23A duty at 440 V AC — meaning it handles motor and mixed loads with frequent switching, not just resistive circuits. The 3-pole design suits three-phase distribution panels where you need visible-break isolation (IEC 60947-3 certified). Mounts on a rail base plate with rear connection; the 70 mm connection pitch without spreader keeps busbar layout clean.
The headline number is 1600 A in AC-23A — that's the current it can make and break for motor loads (high inrush, up to 10× running). For distribution-only duty (AC-21A or AC-22A) it would carry more, but AC-23A is the tougher call. The short-time withstand (Icw) is 50 kA for 1 second at 220-440 V; the making capacity (Icm) is 75 kA. That tells you it can sit upstream of a fault and hold closed long enough for a downstream breaker to clear — selectivity headroom. Electrical durability: 5000 cycles at 440 V in AC-23A without maintenance. Mechanical durability: 20,000 cycles with maintenance, 10,000 without. That's not a daily-switch duty cycle; it's a load-break isolator for infrequent operation.
