800 A drawout disconnector for distribution
The ENW24277 is a 4-pole switch disconnector from the EasyPact NW range, rated 800 A in AC-23A utilisation category at 690 V AC — meaning it handles motor switching and mixed loads with frequent on-load operation, not just passive isolation. Drawout mounting on a rail allows the unit to be withdrawn for inspection or replacement without disturbing main bus connections; the 115 mm connection pitch without spreader keeps the footprint predictable in retrofit panels. Rated for continuous duty and certified as an isolating switch per IEC 60947-3, it provides visible break confirmation via the contact position indicator — a practical check for lockout/tagout on distribution feeders.
Breaking capacity and coordination headroom
Short-time withstand current (Icw) is 66 kA for 1 s and 36 kA for 3 s at rated temperature range, with a making capacity (Icm) of 143 kA peak. That gives selectivity headroom downstream — the disconnector stays closed through a fault long enough for the branch breaker to clear, avoiding a full bus outage.
Active lifecycle and sourcing posture
Active lifecycle status.
Drawout mechanism on rail support — panel builders should allow extraction clearance equal to the 395 mm depth plus handle swing. Rear connection, horizontal or vertical orientation. IP40 enclosure protection (tools and hands, not washdown). Neutral on the right side of the 4-pole assembly.
