It's a 3-pole unit built for line protection, meaning it guards the feeder, not a specific motor or load. That auxiliary stack gives you remote status — open/closed and tripped — without adding a separate module. The shunt trip lets you drop the breaker remotely via a control signal, which is handy for emergency-off circuits or PLC-driven load shedding. ## Breaking capacity across voltages — the selectivity story At 240 V it interrupts 75.6 kA; at 415 V that drops to 52.5 kA; at 440 V it's 32 kA; at 500 V and 690 V it holds at 11.9 kA. Those numbers govern your selectivity study — if your upstream transformer can push 65 kA at 480 V, this breaker at 32 kA (440 V) won't coordinate unless you step up to a higher-rated frame upstream. For a 240 V delta panel or a 400 V wye with moderate fault current, it's a solid fit. ## Thermal derating and ambient reality At 55 °C it's 78 A, at 60 °C it's 77 A, at 65 °C it's 75 A, and at 70 °C it's 74 A. The max power loss is 19.2 W, which matters for enclosure heat calc if you're stacking several breakers.","metaTitle":"Siemens 3VA1180-3EE32-0KH0 SENTRON MCCB, 80A, 75.6kA","metaDescription":"Siemens SENTRON 3VA1180-3EE32-0KH0 molded case circuit breaker, 80A rated at 40°C, 75.6kA breaking at 240V, 3-pole, shunt trip.
