The Schneider Electric ENW24204 is a 3-pole drawout switch disconnector from the EasyPact NW range, rated for 4000 A in AC-23A utilisation category at 690 V AC. The 66 kA short-time withstand for 1 second (36 kA for 3 seconds) tells you it holds through downstream faults until an upstream breaker clears them.
Drawout mounting on a rail, with rear connection. The 115 mm connection pitch without spreader sets the busbar spacing — standard for this class of high-current switch. IP40 enclosure protection means it is suited for indoor panel installation where tools are needed to access live parts. Pollution degree 4 per IEC 60664-1 confirms it handles conductive dust and condensation environments typical in heavy industrial switchgear rooms.
The headline 4000 A is the AC-23A operational current at 690 V — that is the motor-switching duty rating, not a resistive-heater rating. Suitability for isolation per IEC 60947-3 means it provides visible-break isolation when open — a requirement for lockout/tagout on distribution feeders.
