Product details

The ENW13278 is a 3-pole switch disconnector from the Schneider Electric EasyPact NW range, rated 630 A in AC-23A utilisation category at 440 V AC. The drawout mounting allows the switching element to be withdrawn from the cradle for maintenance or replacement without disturbing the main bus connections — a feature that reduces downtime in switchboard and MCC lineups.

The 630 A rated operational current (Ie) in AC-23A covers motor starting and mixed resistive-inductive loads — the category for frequent switching of motors, transformers, and capacitor banks. The 50 kA rated short-time withstand current (Icw) for 1 second at 220–440 V means this switch can hold closed through a fault long enough for an upstream protective device to clear, preserving selectivity in a distribution panel. The 75 kA rated short-circuit making capacity (Icm) confirms it can close onto a fault without welding contacts. Suitability for isolation per IEC 60947-3 is confirmed, so the switch can serve as a visible-break disconnecting means for a downstream load. The contact position indicator gives a clear visual confirmation of open or closed state.

The ENW13278 carries an active lifecycle status from Schneider Electric. It is a current-production part within the EasyPact NW family, so it remains a qualified BOM line for new switchboard builds and replacement spares.
