The ENW13285 is a 3-pole switch disconnector from the EasyPact NW range, rated 1000 A in AC-23A duty at 440 V — that's the utilisation category for switching motor loads and other highly inductive circuits, not just resistive. AC-23A covers occasional switching of motors, transformers, and capacitor banks, so this part is sized for distribution panels feeding motor control centres or heavy plant loads. The 50 kA short-time withstand (Icw) for 1 second and 75 kA making capacity (Icm) at 220–440 V mean it can hold in through a downstream fault and close onto a short circuit without welding contacts — critical for a main disconnector in an industrial switchboard. Rated insulation voltage (Ui) is 1000 V AC, impulse withstand (Uimp) is 12 kV, and it's certified for isolation per IEC 60947-3 — so it doubles as a visible-break isolating point for lockout/tagout.
Deployment context
Fixed-mount design on a rail base plate, with rear connection and a 70 mm connection pitch without spreader. Mechanical durability is 20,000 cycles with maintenance, 10,000 without; electrical durability under AC-23A at 440 V is 5,000 cycles without maintenance. That's a solid service life for a main disconnect that sees maybe a few operations per shift.
