It's built for line protection — meaning it sits upstream of a distribution bus or a large load group, not as a dedicated motor starter. The interrupting ratings climb to 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V, so it handles high-fault utility feeds without cascading upstream. At 690 V it still clears 11.9 kA, which matters for industrial 690 V networks common in mining or marine. At 55 °C it drops to 76.8 A, and at 70 °C it's 72 A. If your enclosure runs hot, size the load to the 70 °C figure, not the nameplate 80 A. The 3VA1080-4ED42-0JC0 measures 130 mm high, 101.6 mm wide, and 70 mm deep — a standard MCCB footprint for a 4-pole 80 A frame. If you need those, this isn't the variant.","metaTitle":"Siemens 3VA1080-4ED42-0JC0 SENTRON MCCB, 80 A, 4-Pole, 121 k","metaDescription":"Siemens 3VA1080-4ED42-0JC0 SENTRON molded case circuit breaker, 80 A rated, 4-pole, 121 kA at 240 V.
