Breaking capacity is 187 kA at 240 V AC, 121 kA at 415 V, 76 kA at 440 V, and 30 kA at 500 V — enough headroom for most industrial fault-current scenarios without cascading upstream. Rated insulation voltage (Ui) is 690 V, and max DC operational voltage is 500 V, so it suits both AC and DC distribution panels. ## Current rating vs. ambient temperature The 200 A rating holds flat from 40 °C through 50 °C, then derates linearly to 176 A at 70 °C — useful when the breaker lives in a warm enclosure near other heat sources. Maximum power loss is 42 W, which factors into enclosure thermal calculations, especially in a multi-breaker lineup.","metaTitle":"Siemens 3VM1220-5EE42-0AA0 SENTRON MCCB, 4-Pole, 200 A, TM22","metaDescription":"Siemens SENTRON 3VM1220-5EE42-0AA0 molded case circuit breaker, 4-pole, 200 A rated at 40 °C, TM220 release, 187 kA at 240 V.
