The interrupting capacity hits 440 kA at 240 V, stepping down to 242 kA at 415/440 V and 187 kA at 500 V, with 73.5 kA still on tap at 690 V. That's a main or feeder breaker sized for high-fault industrial services where upstream coordination demands full-rated SCCR. The ETU860 electronic trip unit handles line protection with adjustable N-conductor protection (OFF, 20% to 160%), ground-fault monitoring via summation current formation on the L-conductor, and a communication function onboard. Front IP40, storage from -40 °C to 80 °C, operating range -25 °C to 70 °C. Dimensions 320 mm high, 210 mm wide, 120 mm deep — fits standard panel layouts with adequate side clearance for arc flash containment.","metaTitle":"Siemens 3VA2563-7KQ32-0AA0 SENTRON MCCB, 630 A, 440 kA IC","metaDescription":"Siemens SENTRON 3VA2563-7KQ32-0AA0 molded case circuit breaker, 630 A rated, 440 kA interrupting at 240 V.
