The TM240 thermal-magnetic release handles overload and short-circuit trip coordination; the undervoltage release (UVR) lets a safety circuit or E-stop drop the breaker without a manual trip. This breaker interrupts 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V (–). Those are the maximum fault currents it can clear without welding or rupturing. For a 480 V panel in North America, the 75.6 kA at 440 V is the closest published figure — expect similar capability at 480 V, but the 415 V rating (121 kA) is the one to use for IEC 60947-2 verification in a 400 V system. ## Thermal derating — it stays at 200 A until 50 °C Above that it derates: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C (–). If your panel ambient hits 60 °C, you lose 12 A — plan the load accordingly. The breaker measures 140 mm wide, 158 mm high, 70 mm deep. It is a 4-pole unit with no communication function and no ground-fault monitoring. The undervoltage release is factory-fitted; no voltage-trigger accessory is included.","metaTitle":"Siemens 3VA1220-5GF42-0BA0 SENTRON MCCB, 200 A, 4-Pole, TM24","metaDescription":"Siemens 3VA1220-5GF42-0BA0 SENTRON molded case circuit breaker, 200 A rated, 4-pole, TM240 release, 187 kA at 240 V.
