It carries a continuous current rating of 200 A up to 50 °C, derating to 176 A at 70 °C — the full thermal curve is documented so you can size for actual panel ambient, not just the nameplate. Breaking capacity is voltage-dependent: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V. That spread covers most low-voltage distribution and motor-control panels across global voltage standards — the 415 V figure is the one to check for IEC 60947-2 coordination studies in 400 V-class systems. ## Sizing and thermal performance Rated insulation voltage is 800 V, and the operating temperature range spans -25 °C to 70 °C, with storage from -40 °C to 80 °C. Maximum power loss is 42 W — relevant for enclosure heat-rise calculations when grouping multiple breakers in a panel. Dimensions are 105 mm wide, 158 mm high, and 70 mm deep — a standard SENTRON 3VA footprint that fits existing Siemens panel layouts and busbar systems without re-drilling.","metaTitle":"Siemens 3VA1220-4EF32-0JA0 SENTRON MCCB, 200 A, 3-Pole, Shun","metaDescription":"Siemens SENTRON 3VA1220-4EF32-0JA0 molded case circuit breaker, 200 A at 40 °C, 3-pole, TM240 release, shunt trip (STL).
