The adjustable thermal-magnetic trip unit covers 95 A minimum to 756 A maximum, so this frame size handles everything from a modest feeder to a heavy downstream bus without swapping the breaker body — just dial the trip setting. Breaking capacity is the headline number that decides whether this breaker clears a fault or welds shut: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. ## Built-in undervoltage release and ground-fault monitoring That is standard for applications where a voltage dip must disconnect the load (conveyor interlock, emergency-stop chain, or generator transfer schemes). That is a common configuration for solidly-grounded systems where you want ground-fault protection without a separate GFCI module. A communication function is built in — the breaker can report status and trip events to a higher-level control system, which saves chasing a remote-indication relay later. This is a standard-catalog SENTRON MCCB, so lead times typically track the normal Siemens distribution cycle for the 3VA2 frame. The 86 mm depth (3.39 in) is shallow enough for shallow-backpan cabinets.","metaTitle":"Siemens 3VA2063-5JQ32-0BA0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2063-5JQ32-0BA0 molded case circuit breaker, 3-pole, 63 A rated, 95-756 A trip range, 187 kA breaking at 240 V.
