Its breaking capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V, so it handles high-fault utility feeds and transformer secondaries without cascading upstream. The design is line protection, meaning it guards distribution feeders and main switchboards rather than individual motor loads. Ground-fault monitoring uses summation current formation on L + N conductors, which catches leakage without a separate core-balance transformer. Rated insulation voltage is 800 V, so the breaker is comfortable in 480/277 V and 600 V panels and can be applied in 690 V systems where the interrupting rating is adequate. It mounts directly onto a DIN rail or into a panel via the rear mounting slots; the 140 mm width fits a 4-pole MCCB cutout in most switchboard chassis. No special adapter plate needed for common enclosure layouts. ## Communication and monitoring capability The breaker includes a communication function, which on the SENTRON 3VA2 platform typically means an integrated Modbus RTU or PROFIBUS interface for remote trip indication, current metering, and parameter readback. This allows the MCCB to report into a building management system or industrial SCADA without an external current transformer or I/O module. Ground-fault monitoring is built in as summation current formation on L + N, so it detects leakage down to the trip threshold without a separate relay.","metaTitle":"Siemens 3VA2163-6JQ42-0AA0 SENTRON MCCB, 63 A, 4-Pole, 242 k","metaDescription":"Siemens SENTRON 3VA2163-6JQ42-0AA0 molded case circuit breaker, 63 A continuous, 4-pole, 242 kA breaking at 240 V.
