The interrupting ratings climb to 121 kA at 240 V, 75.6 kA at 415 V, 25 kA at 440 V, and 11.9 kA at 690 V, so it handles high-fault utility feeds and transformer secondaries without cascading upstream. Above that it derates: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C. The undervoltage release is a factory-integrated option (order code suffix indicates the UVR is built in, not a field-addon kit). No official successor or phase-out notice is on record. The 105 mm width occupies three 35 mm module spaces; the 70 mm depth leaves room for rear busbar connections in a typical 200 mm deep enclosure. The front IP40 rating means it is not suitable for washdown areas — keep it inside a sealed cabinet. The TM240 release is fixed-trip (thermal-magnetic, not electronic), so coordination studies rely on the published time-current curve for the 3VA platform.","metaTitle":"Siemens 3VA1220-4EF32-0CA0 SENTRON MCCB, 200 A, 3-Pole, Line","metaDescription":"Siemens 3VA1220-4EF32-0CA0 SENTRON molded case circuit breaker, 200 A rated continuous current, 3-pole, line protection, 70 mm depth, 105 mm width.
