Interrupting 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 — figures that cover most industrial distribution panels up to 690 V line-to-line. An undervoltage release (UVR) is fitted as standard. Dimensions: 105 mm wide, 158 mm high, 70 mm deep. Fits standard Siemens SENTRON mounting base or DIN-rail adapter. The 3-pole footprint is the same across the 3VA1 frame; if you're swapping a 3VA1 160 A frame, check the depth — this unit is 70 mm, matching the frame depth for the 200 A rating.","metaTitle":"Siemens 3VA1220-4EF32-0BA0 SENTRON MCCB, 200 A, 3-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1220-4EF32-0BA0 molded case circuit breaker, 200 A rated at 40 °C, 3-pole, TM240 release, 121 kA at 240 V.
