That steep roll-off above 500 V means this is a 480 V class MCCB — do not spec it for a 600 V feeder expecting the same fault-clearing muscle. ## Auxiliary switch and shunt trip — what is wired in It also carries a shunt trip (STL) release. That means you get remote trip capability and status feedback without opening the breaker cover to add accessories — useful for a panel where the MCCB is part of an E-stop chain or monitored by a PLC. Power loss is listed at 5.4 W maximum. That is low enough that thermal rise inside a crowded enclosure is manageable, but if you are stacking several of these on a bus, add it to your enclosure heat budget.","metaTitle":"Siemens 3VA2063-6HN32-0JL0 SENTRON MCCB, 63A, 3-Pole, 242kA","metaDescription":"Siemens 3VA2063-6HN32-0JL0 SENTRON molded case circuit breaker, 63 A continuous, 3-pole, interrupting ratings up to 242 kA at 240 V.
