At 480/277 V systems — common in North American industrial — the 242 kA at 440 V is the closest published figure, and it still gives substantial headroom over a typical 65 kA or 100 kA rated panel. The steep drop to 3 kA at 690 V means this isn't a 690 V main breaker; it's a 240–500 V device with a very high short-circuit rating in that band. ## Thermal performance and panel integration That means you can pack it into a panel running hot without recalculating the load schedule. The 7.7 W maximum power loss is the heat it dumps into the enclosure; for a 100 A 4-pole breaker that's modest, so it won't drive extra cooling in most cabinets.","metaTitle":"Siemens 3VA2010-7HL42-0AA0 SENTRON MCCB, 100 A, 4-Pole, ETU3","metaDescription":"Siemens 3VA2010-7HL42-0AA0 SENTRON molded case circuit breaker, 100 A continuous, 4-pole, ETU320 electronic trip unit.
