At 415 V the breaking capacity is still 154 kA, and it tapers to 17 kA at 690 V — so it stays usable on 400 V-class systems without a second tier of current-limiting fuses. ## Ratings that drive the choice At 55 °C it derates to 194 A, at 60 °C to 188 A, and at 70 °C to 176 A. If the panel sits near a heat source or in a hot plant, that derating curve tells you whether this frame size still works or you need to step up to the next amp rating. The TM240 release means the thermal element is calibrated for a 200 A frame with a 240 A fixed magnetic pickup — typical for protecting cables or busbars against overloads while clearing high-impedance faults fast. Power loss is 42 W maximum at rated current — that is heat that stays inside the enclosure. Verify the busbar spacing and the mounting footprint against your existing panel layout; the SENTRON 3VA family uses a common bolt pattern across the frame sizes, so swapping within the family usually avoids drilling new holes.","metaTitle":"SENTRON 3VA1220-6EF42-0AA0 MCCB, 200 A, 4-Pole, TM240, 220 k","metaDescription":"Siemens SENTRON 3VA1220-6EF42-0AA0 molded case circuit breaker, 200 A, 4-pole, TM240 release, 220 kA at 240 V.
