Breaking capacity is 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 covers most industrial distribution panels up to 690 V line-to-line. The 3-pole construction fits three-phase feeds, and the TM240 thermal-magnetic release provides short-circuit and overload protection. A shunt trip release (STL) is built in — voltage-triggered remote tripping for emergency stop or supervisory control. The 105 mm width and 158 mm height match the standard SENTRON 3VA panel footprint. Dimensions: 105 mm wide, 158 mm tall, 70 mm deep.","metaTitle":"Siemens 3VA1220-4EF32-0KA0 SENTRON MCCB, 200 A, 3-Pole, Shun","metaDescription":"Siemens 3VA1220-4EF32-0KA0 SENTRON molded case circuit breaker, 200 A rated at 40 °C, 3-pole, 121 kA at 240 V.
