At 415 V it handles 121 kA, at 440 V it's 75.6 kA, and at 500 V or 690 V it still manages 17 kA. That voltage-dependent curve tells you where it's comfortable — feed it from a 480 V transformer and the 75.6 kA at 440 V is your closest reference point; on a 600 V class system the 17 kA at 690 V is the ceiling. ## Thermal derating — don't just read the 80 A label Above that it starts to taper: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. ## Built-in accessories — shunt trip and aux switches It also carries two auxiliary switches (HQ) for status feedback to a control system or a panel lamp. If you need those, this isn't the variant; look at the 3VA1 family options with a UVR or a COM module. ## Physical fit — panel footprint That 3-inch (76.2 mm) width per pole is standard for SENTRON 3VA1 MCCBs in the 80 A frame size, so it drops into a 3-pole cutout without surprises. Depth of 70 mm (2.76 in) means it clears most shallow backpan enclosures — check your deadfront clearance if the panel has a door-mounted operator.","metaTitle":"Siemens 3VA1180-5EF32-0JC0 SENTRON MCCB, 80A, 3-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA1180-5EF32-0JC0 molded case circuit breaker, 80A, 3-pole, 187kA breaking capacity at 240V.

The terminal layout and bus-bar centers match. The main difference is the rating: the 3VA1180 is an 80 A breaker with a shunt trip and two aux switches, while the 3VA1110-5ED36-0AC0 is a lower-current variant. If your load is within 80 A and you need the shunt trip, it's a drop-in swap without rewiring."},{"question":"What compliance documentation does Siemens provide for 3VA1180-5EF32-0JC0?","answer":"Siemens SENTRON MCCBs carry CE marking for the European market and are designed to meet IEC 60947-2.
