The 3-pole unit delivers a short-circuit breaking capacity of 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V, so it handles high-fault scenarios common in industrial mains distribution. At 415 V it still interrupts 75.6 kA, and at 440 V it handles 52.5 kA — both figures that cover most industrial secondary distribution faults. At 500 V and 690 V the rating drops to 11.9 kA, which is still adequate for many motor control center applications but not for high-fault 690 V buswork. The two auxiliary switches provide status feedback (open/closed) to a PLC or indication lamp without needing additional add-on modules. The 3-pole width (76.2 mm) is standard for this frame size — it fits the usual DIN-rail or panel-mount footprint for SENTRON 3VA breakers. No communication function or ground-fault monitoring is built in; this is a straight line-protection device with undervoltage release.","metaTitle":"Siemens 3VA1080-4ED32-0BC0 SENTRON MCCB, 80A, 3-Pole, 121kA","metaDescription":"Siemens 3VA1080-4ED32-0BC0 SENTRON molded case circuit breaker, 80A rated at 40°C, 3-pole, 121kA breaking at 240V.

It will not drop into the same panel without checking the frame size and busbar spacing — the 3VA1080 is an 80 A frame, while the 3VA1110 is a 100 A+ frame with different dimensions. For a direct functional match at 80 A, stick with the 3VA1080-4ED32-0BC0 or its siblings in the same frame size."},{"question":"What is 3VA1080-4ED32-0BC0's listed depth (70 mm) on this component line?","answer":"The depth is 70 mm (2.76 in), which is the dimension from the mounting surface to the front of the breaker — important for enclosure depth clearance."},{"question":"What is 3VA1080-4ED32-0BC0's listed width (76.2 mm) on this component line?","answer":"The width is 76.2 mm (3 in), which is the standard 3-pole width for this SENTRON 3VA frame size."},{"question":"Will 3VA1080-4ED32-0BC0 drop into a panel that was specified around 3VA1110-5ED36-0AC0 without rewiring?","answer":"No — the 3VA1110-5ED36-0AC0 is a larger frame size (higher current rating, different physical dimensions).
