The EVS12H3MF20 is a 3-pole molded case circuit breaker from Schneider Electric's EasyPact EVS range, rated 1250 A at 40 °C with an electronic trip unit (EVS Trip System2.0) providing overload and instantaneous short-circuit protection (LI). Breaking capacity is 65 kA Icu at 220–440 V AC and 50 kA Icu at 690 V AC, per IEC 60947-2.
Fixed mounting on a rail base plate, rear-connected, with a connection pitch of 115 mm without spreader. Dimensions: 422 mm wide, 352 mm high, 297 mm deep. IP40 protection — suitable for enclosed panel installation, not washdown environments. Pollution degree 4 per IEC 60664-1 means it tolerates conductive dust and heavy industrial atmospheres, so it belongs in a sealed MCC or distribution cabinet, not an open floor-mount.
Durability and Duty
Category B utilization — designed for distribution, not direct motor starting. Mechanical durability: 20,000 cycles with maintenance, 10,000 without. Electrical durability: 5,000 cycles at 440/690 V without maintenance. Maximum breaking time 25 ms, closing time 70 ms.
