At 415 V it still holds 154 kA, and at 440 V it drops to 36 kA; at 690 V the rating is 17 kA. These are the values that govern coordination with upstream switchgear; if your panel's prospective fault current at the breaker terminals exceeds the applicable voltage-column rating, you need a current-limiting fuse ahead or a larger frame. Thermal derating is flat at 250 A from 40 °C through 50 °C, then steps down to 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, and 223 A at 70 °C. ## Release and accessory configuration The shunt trip (STL) is factory-fitted — order code 3VA9688-0BL32 for the integrated auxiliary trip if you need a spare. No auxiliary contact version is included; if you need status feedback to a PLC, you add a separate auxiliary switch block. The width of 105 mm matches the standard 3VA frame footprint; if your existing panel was built around a 3VA1010 frame (100 A class), the mounting hole pattern and bus-bar centres are identical, so this 250 A unit drops in without rewiring the bus.","metaTitle":"Siemens SENTRON 3VA1225-6EF32-0JA0 MCCB, 250 A, 3-Pole, 220","metaDescription":"Siemens SENTRON 3VA1225-6EF32-0JA0 molded case circuit breaker, 250 A, 3-pole, line protection, TM240 release, 220 kA at 240 V.

Both breakers share the same 3VA frame footprint — 105 mm width and identical mounting centres. The 250 A unit fits the same bus-bar and DIN-rail layout as the 100 A 3VA1010, so no rewiring is required for the mechanical fit.
