This MCCB carries a 330 kA interrupting rating at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. Those are the maximum fault currents it can safely clear at each voltage level. ## Built-in undervoltage release — what it means for your control scheme This is standard for machinery where you want the breaker to open on loss of control power (e-stop chain, safety relay output). The UVR is a separate device inside the breaker; if you don't need it, you'd order the -0AA0 variant instead. No auxiliary contact version is included on this order code — if you need a status feedback contact, you'll add one externally. The IP40 front protection means it's splash-proof on the front face but not sealed; mount it inside a panel with at least an IP54 enclosure if the environment is wet. Maximum power loss is 75 W — that's the heat it dumps into the enclosure at full rated current, so factor that into your thermal calculation if you're packing multiple breakers in a small cabinet.","metaTitle":"Siemens 3VA2220-7MS32-0BA0 MCCB, 200 A, 330 kA at 240 V","metaDescription":"Siemens SENTRON 3VA2220-7MS32-0BA0 molded case circuit breaker, 200 A rated, 330 kA breaking capacity at 240 V.
