Schneider Electric E125N320FM EasyPact CVS1250N 3P 1250 A 50 kA ETS 2.0 Fixed Moulded Case Circuit Breaker

The Schneider Electric E125N320FM is a 1250 A EasyPact CVS1250N 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 3-pole, 3D 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 3-pole frame protects the three phase conductors only; use it on a balanced three-phase feeder where the neutral is bonded upstream or not distributed. Within the 1250 A CVS1250 frame size, E125N320FM (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 (500 A) and cannot raise the frame's current rating.
