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.","metaTitle":"Siemens 3VA2163-8JQ36-0AA0 SENTRON MCCB, 63 A, 3-Pole, 440 k","metaDescription":"Siemens SENTRON 3VA2163-8JQ36-0AA0 molded case circuit breaker, 63 A continuous, 3-pole, 440 kA breaking at 240 V.
