The Siemens SENTRON 3VA1180-3ED32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated 80 A continuous at 40 °C, fitted with a TM210 thermal-magnetic release for line protection. It's designed for distribution panels and motor branch circuits where you need adjustable thermal pickup and fixed magnetic instant trip — the TM210 gives you a 2:1 thermal adjustment range (0.7–1.0× In) and a fixed magnetic trip at 10× In, so it handles motor inrush without nuisance trips on the thermal side. Interrupting capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V and 690 V — that covers most industrial service entrances and sub-distribution boards without needing a current-limiting fuse upstream.
At 130 mm high, 76.2 mm wide, and 70 mm deep, this MCCB fits a standard 3-pole breaker slot in most Siemens SENTRON panelboards and switchgear. The 76.2 mm width matches the 3-inch (76.2 mm) modular spacing common in North American panel schedules — you can swap it into an existing 3-pole position without re-drilling the mounting plate.
Above 50 °C it drops linearly: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, 74 A at 70 °C. If your panel ambient hits 70 °C, you've still got 74 A of headroom. In a sealed NEMA 4X box with multiple breakers, add those losses up for the thermal budget.
