Its interrupting capacity hits 75.6 kA at 240 V AC, stepping down to 52.5 kA at 415 V and 32 kA at 440 V — numbers that tell you it handles high-fault utility feeds or transformer-secondaries without cascading upstream. The 80 A rating holds flat from 40 °C through 50 °C — no derating needed in a warm enclosure until you cross 55 °C, where it drops to 78 A, then 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. That's a shallow derate curve; you can push the ambient without losing much headroom. The TM240 release means the thermal pickup is fixed at 80 A (the frame rating), with magnetic trip at 240 A — 3x the continuous, typical for motor or distribution feeder protection where you want short-circuit discrimination but not nuisance tripping on inrush. Interrupting capacity at 690 V is still 11.9 kA, so this breaker can serve as the main on a 690 V sub-distribution board if the fault current stays under that. The 19.2 W maximum power loss is modest for an 80 A frame — helps keep internal panel temperature rise in check when you're stacking multiple breakers on a DIN rail assembly. Width is 76.2 mm (3 in), depth 70 mm (2.76 in), height 130 mm (5.12 in) — a standard 3-pole MCCB footprint that drops into SENTRON distribution boards or onto a mounting plate with the matching busbar system. The 2 auxiliary switches (HP type) are built in, so you get status feedback without an add-on module.","metaTitle":"Siemens SENTRON 3VA1180-3EF32-0AB0 MCCB, 80 A, 75.6 kA at 24","metaDescription":"Siemens SENTRON 3VA1180-3EF32-0AB0 molded case circuit breaker, 3-pole, 80 A (40 °C), TM240 release, 75.6 kA interrupting at 240 V.
