It carries a 242 kA breaking capacity at 240 V, stepping down to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V — per the datasheet, the interrupting rating at each voltage level is a fixed value, not a conditional short-circuit current. This MCCB is designed for line protection duty in main or feeder distribution panels. The 630 A frame covers large motor control centers, transformer secondaries, or busway feeds where selectivity with downstream breakers is required. The ETU560 release allows fine coordination: the short-time pickup and delay settings let you ride through inrush without nuisance tripping, while the ground-fault element (summation current formation on L-conductor) detects leakage without a separate core-balance CT. ## Thermal derating and power dissipation Derate to 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. ## Coordination and selectivity notes The ETU560 release supports LSI (long-time, short-time, instantaneous) protection plus ground fault. The short-time delay setting allows full selectivity with downstream 3VA breakers up to the short-time withstand rating. The 15 000 mechanical endurance cycles (latching endurance) is typical for a 630 A frame in distribution duty — not intended for frequent switching, but adequate for infrequent maintenance operations.","metaTitle":"Siemens 3VA2463-6JQ32-0AG0 SENTRON MCCB, 630 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-6JQ32-0AG0 molded case circuit breaker, 630 A rated continuous current, 242 kA breaking capacity at 240 V.
