Schneider Electric E080N420FM EasyPact CVS800N 4P 800 A 50 kA ETS 2.0 Fixed Moulded Case Circuit Breaker

The Schneider Electric E080N420FM is a 800 A EasyPact CVS800N moulded case circuit breaker for low-voltage electrical distribution, built on a medium-to-high breaking N frame. Its ETS 2.0 electronic trip unit gives adjustable long-time overload and instantaneous short-circuit protection (LI), and the 4-pole, 4D frame breaks 50 kA at 380/415 V AC under IEC 60947-2.

Selection Notes

Pick the N frame as the mid-tier option: 50 kA at 380/415 V covers most distribution boards without paying for the H frame's extra breaking capacity. The 4-pole frame adds switched neutral protection, selectable at 0.5 x Ir for a half-protected N/2 conductor or 1 x Ir for a fully protected neutral -- relevant on TT or TN-S systems carrying unbalanced single-phase loads. Within the 800 A CVS800 frame size, E080N420FM (N class) sits alongside breaking-class siblings at the same amperage -- move up a class if downstream fault studies show higher prospective short-circuit current than 50 kA at 380/415 V, since the ETS 2.0 long-time setting only trims down to 0.4 x In (320 A) and cannot raise the frame's current rating.
