Schneider Electric E125F420FM EasyPact CVS1250F 4P 1250 A 36 kA ETS 2.0 Fixed Moulded Case Circuit Breaker

The Schneider Electric E125F420FM is a 1250 A EasyPact CVS1250F moulded case circuit breaker for low-voltage electrical distribution, built on a standard-breaking F 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 36 kA at 380/415 V AC under IEC 60947-2.

Selection Notes

Pick the F frame where available fault current stays under 36 kA at 380/415 V; it is the lightest-duty, lowest-cost frame in this CVS range. 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 1250 A CVS1250 frame size, E125F420FM (F 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 36 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.
