The ENW24219 is a 4-pole switch disconnector from the EasyPact NW range, rated for 3200 A in AC-23A duty at 690 V AC — that's the utilization category for heavy motor loads, including frequent starting and plugging. It's built to IEC 60947-3 and carries a 1000 V insulation rating, so it's suitable for isolation (the standard says yes). The drawout mounting means the moving contact assembly can be withdrawn from the fixed base for safe inspection or replacement without breaking the main bus connections.
The short-time withstand current (Icw) is 66 kA for 1 second, and the short-circuit making capacity (Icm) is 143 kA peak at 50/60 Hz. That combination means it can hold closed through a high fault current for a full second and then safely close onto a short circuit. The impulse withstand voltage (Uimp) is 12 kV, which covers typical distribution-level transient overvoltages.
This is a drawout switch disconnector designed for distribution panels. It mounts on a rail (the evidence says 'Mounting support: Rail') and connects at the rear — horizontal or vertical busbar orientation. The neutral pole is on the left, and the connection pitch is 115 mm without a spreader.
