The interrupting ratings are substantial: 220 kA at 240 V, 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V, so it handles high-fault-capacity utility feeds without cascading upstream. The TM240 release is a fixed thermal-magnetic type — no interchangeable rating plugs, so the 250 A frame is locked at that trip curve. For ambient derating: the breaker holds 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. ## Integration — Panel Fit and Auxiliary Wiring Dimensions: 70 mm deep, 140 mm wide, 158 mm high. That 140 mm width on a 4-pole frame is standard for SENTRON 3VA — it occupies the same footprint as other 250 A 4-pole variants in the series. The shunt trip coil (STL) and auxiliary switches are wired via the integrated terminal block; the auxiliary trip accessory order code is 3VA9688-0BL32 if you need a replacement or spare.","metaTitle":"3VA1225-6GF42-0JC0 SENTRON MCCB, 250 A, 4-pole, 220 kA at 24","metaDescription":"Siemens SENTRON 3VA1225-6GF42-0JC0 molded case circuit breaker, 250 A, 4-pole, TM240 release, 220 kA at 240 V.
