That thermal curve means this breaker handles full load in a warm panel without nuisance tripping — useful when the enclosure sits near process heat or in a non-climate-controlled electrical room. ## Breaking capacity by voltage level The interrupting ratings are given at five voltage points: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. The breaker measures 140 mm wide by 158 mm high by 70 mm deep. The 4-pole width (140 mm) matches the common 4-module footprint for SENTRON 3VA breakers, so a panel laid out for a 3VA1110 frame accepts this one without re-drilling the mounting plate. ## Auxiliary and internal configuration The breaker ships with three auxiliary switches (HQ type) installed. If your application needs shunt trip or UVR, you add those as external accessories; the breaker body itself is a straight thermal-magnetic line-protection device with auxiliary contacts for status feedback. Maximum power loss is 42 W — that's the heat to account for in the enclosure thermal calculation.","metaTitle":"Siemens 3VA1220-6EF42-0AD0 SENTRON MCCB, 200 A, 4-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1220-6EF42-0AD0 molded case circuit breaker, 200 A at 40 °C, 4-pole, TM240 release, 220 kA at 240 V.
