Switch disconnector for distribution — 1600 A, AC-23A, 4 poles
The Schneider Electric ENW24224 is a fixed-mount switch disconnector from the EasyPact NW range, rated 1600 A in AC-23A duty at 690 V AC. The 4-pole configuration with neutral on the left suits distribution panels where a switched neutral is required. Rated short-time withstand current is 66 kA for 1 second (36 kA for 3 seconds), and the short-circuit making capacity reaches 143 kA peak. These figures, combined with a rated impulse withstand voltage of 12 kV and pollution degree 4 (the highest severity per IEC 60664-1), tell you this unit is built for high-fault-capacity industrial distribution — not light commercial duty. Mechanical durability is 20,000 cycles with maintenance, 10,000 without; electrical durability under AC-23A is 6,000 cycles at 440 V and 4,000 cycles at 690 V. That is typical for a switch disconnector in this class — it is a load-break device, not a daily-operating contactor.
Fixed mounting on a base plate. Dimensions are 537 mm wide by 352 mm high by 297 mm deep. Connection pitch is 115 mm without spreader; rear connection position, horizontal or vertical orientation. IP40 protection — suitable for indoor panel installation, not for washdown environments. The contact position indicator gives a visual confirmation of open/closed state, which is useful during commissioning and lockout/tagout procedures.
