That frame size tells you the internal mechanism and contacts are physically sized for 800 A — the breaker is thermally-magnetically limited to 80 A by its TM220 trip unit, so it's a line-protection device, not a feeder breaker. The interrupting ratings climb as voltage drops: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The breaker's dimensions — 130 mm high, 76.2 mm wide, 70 mm deep — fit the standard SENTRON 3VA panel footprint. That 76.2 mm width (3 inches) is the same as other 3VA frame sizes in this range, so it swaps into an existing 3VA mounting base without re-drilling the panel. The 70 mm depth keeps it clear of most gland plates and backpanel wiring troughs. ## Thermal Derating — Where the 80 A Rating Holds and Where It Doesn't Above 50 °C it steps down: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. That's about a 7.5% drop from 50 °C to 70 °C, which is modest for a thermal-magnetic breaker. If your enclosure sits near a furnace or in a hot attic, size the load at 74 A maximum to avoid nuisance tripping on a 70 °C ambient day. ## How It Sits Against the 3VA1110-5ED32-0AA0 The 3VA1110-5ED32-0AA0 is a different frame size and rating within the same 3VA family. The 3VA1180-3EE32-0AA0 uses an 800 A frame with an 80 A TM220 trip; the 3VA1110 series typically uses a smaller frame (likely 160 A or 250 A) with a different trip curve. The wiring lugs and bus-bar connections, however, differ by frame ampacity: the 800 A frame has larger line/load terminals than a 160 A frame. If your existing panel was wired for a 3VA1110-5ED32-0AA0, the 3VA1180-3EE32-0AA0 will bolt to the same mounting holes but may require different lug sizes or bus-bar adapters for the higher frame rating. That's another SKU to check before the line-down swap.","metaTitle":"Siemens 3VA1180-3EE32-0AA0 SENTRON MCCB, 80 A, 3-Pole, 800 A","metaDescription":"Siemens SENTRON 3VA1180-3EE32-0AA0 molded case circuit breaker, 80 A continuous, 800 A frame, 3-pole, TM220 release.
