That means at 415 V it clears a 154 kA fault without upstream fuses needing to open — selectivity headroom for a main or feeder position in a distribution board. ## Thermal derating — where the 200 A holds and where it tapers At 55 °C it derates to 194 A, at 60 °C to 188 A, at 65 °C to 182 A, and at 70 °C to 176 A. If the panel ambient stays under 50 °C, no derating applies. Above that, the TM240 release tracks the thermal curve — the breaker will trip earlier in a hot enclosure if you load it to the full 200 A. For a 200 A continuous load in a 60 °C switchroom, budget for the 188 A limit or select the next frame up. The 100 % N-conductor protection design means the neutral pole is rated for full phase current, not reduced; that matters for 4-wire feeders with harmonic content. ## Power loss and auxiliaries Maximum power dissipation is 42 W. That is the heat the breaker dumps into the enclosure at full load; factor it into the panel thermal budget. The product extension entry notes a motor drive option is available for remote trip/close, but this base order code ships without communication function or ground-fault monitoring.","metaTitle":"Siemens 3VA1220-6GF42-0AA0 SENTRON MCCB, 200 A, 4-Pole, 220","metaDescription":"Siemens 3VA1220-6GF42-0AA0 SENTRON molded case circuit breaker, 200 A, 4-pole, TM240 release.
