Its interrupting capacity hits 220 kA at 240 V and 154 kA at 415 V — numbers that tell you it belongs in high-fault panels like main switchboards, transformer secondaries, or large motor control centers where a standard MCCB would weld shut on a bolted fault. The 105 mm width and 70 mm depth keep it within a standard 600 mm panel depth without forcing a deeper enclosure. ## Thermal-magnetic curve and derating The TM240 release is a fixed thermal-magnetic trip — no interchangeable trip unit, no electronic adjustment. At 40 °C through 50 °C it holds full 250 A; at 55 °C it derates to 243.3 A, at 65 °C to 229 A, and at 70 °C to 223 A. The breaker mounts with a fixed three-pole footprint. Rated insulation voltage is 800 V, covering most 480/600 V distribution systems. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C.","metaTitle":"Siemens 3VA1225-6EF32-0AD0 SENTRON MCCB, 250 A, 220 kA at 24","metaDescription":"Siemens 3VA1225-6EF32-0AD0 SENTRON molded case circuit breaker, 250 A rated continuous current, 220 kA breaking capacity at 240 V.
