Switch disconnector for distribution, 630 A AC-23A
The Schneider Electric ENW13273 is an EasyPact NW switch disconnector rated 630 A in AC-23A utilisation category at 440 V AC — that means it handles motor loads with occasional inrush, not just resistive heating, so it is sized for distribution panels feeding mixed inductive and resistive circuits. Three poles, fixed mounting on a rail base plate, rear connection with 70 mm pitch without spreader. Short-time withstand current 50 kA for 1 s at 220–440 V, making capacity 75 kA — numbers that matter for selectivity coordination downstream of a transformer or main breaker.
Mechanical and environmental ratings
Mechanical durability 20,000 cycles with maintenance, 10,000 without — electrical endurance 5,000 cycles at 440 V AC-23A without maintenance. That is typical for a switch disconnector in distribution duty; the maintenance interval governs the panel builder's PM schedule. IP30 finger protection on the enclosure, suitable for indoor panel mounting where the switch is not directly exposed to washdown or dust ingress.
