Switch disconnector for distribution — 1250 A, 3-pole, drawout
The Schneider Electric ENW24167 is a 3-pole switch disconnector from the EasyPact NW range, rated 1250 A in AC-23A utilisation category at 690 V AC. That AC-23A rating means it handles switching of motors and other highly inductive loads — not just resistive — so it is specified for distribution panels feeding motor control centres or heavy plant loads. The drawout mounting (withdrawal chassis) lets the switch be racked out for isolation without disturbing the main bus connections, which is the standard arrangement for main incomers or tie-breakers in low-voltage switchgear. The short-time withstand current (Icw) is 50 kA for 1 second, and the short-circuit making capacity (Icm) reaches 105 kA peak at 50/60 Hz — figures that govern selectivity and SCCR coordination in the upstream protective scheme.
Drawout integration and panel fit
Mounting is drawout on a rail support, with rear connection terminals. The connection pitch is 115 mm without spreader, and the device accepts both vertical and horizontal busbar orientations. Overall dimensions: 441 mm wide, 439 mm high, 395 mm deep. The contact position indicator gives a visible break confirmation, and the device is marked as suitable for isolation per IEC 60947-3, which is the requirement for a lockable disconnect means.
