The Siemens SENTRON 3VA2163-8JQ36-0AA0 is a 3-pole molded case circuit breaker rated for 63 A continuous current with a full-scale range from 16 A to 63 A, so it covers branch circuits and feeder protection in distribution panels without needing a different frame size for each amp setting. Breaking capacity hits 440 kA at 240 V and still delivers 330 kA at 415 V and 52.5 kA at 690 V — figures that put it squarely in high-fault-current applications like transformer secondaries or large motor control centers where upstream coordination matters.
Integration — panel fit and wiring
Ground-fault monitoring is implemented as summation-current formation on the L-conductor, so it detects leakage by summing the phase currents — a common approach for solidly-grounded systems where you want GF protection without a separate relay.
