The interrupting capacity hits 187 kA at 240 VAC, 121 kA at 415/440 V, and still delivers 75.6 kA at 500 V — numbers that give real headroom for high-fault installations. That flat derating curve is unusual; many MCCBs start stepping down above 40 °C. The adjustable thermal-magnetic trip range spans 95 A minimum to 756 A maximum, so this breaker can be set to protect loads well below its frame rating if needed. The shunt trip (STL) release is built in, so remote tripping from a safety circuit or E-stop is wired directly. Communication function is onboard, meaning it can report status and accept commands over the SENTRON communication bus without an external module.","metaTitle":"Siemens 3VA2163-5JQ32-0KH0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-5JQ32-0KH0 molded case circuit breaker, 3-pole, 63 A rated, 187 kA interrupting at 240 VAC.
