The Siemens 3VA4180-4ED34-0AA0 is a SENTRON 3-pole molded-case circuit breaker (MCCB) rated 80 A at 40 °C ambient, with a TM210 thermal-magnetic release that provides fixed overload and short-circuit protection — no adjustable I²t curve, so it's a straight swap-in for a panel design that already calls for that trip characteristic. Breaking capacity hits 65 kA at 240 VAC and 25 kA at 480 VAC, which covers most North American 480Y/277 V distribution panels and industrial motor control centers where the available fault current is known to be under that threshold. Rated operating voltage goes to 690 VAC.
The 80 A rating holds at 40 °C; above that, the continuous current derates in 1–2 A steps per 5 °C rise, down to 70 A at 70 °C. Maximum power dissipation is 16.5 W, which is modest for an 80 A frame.
Footprint is 76.2 mm wide, 129.4 mm tall, 75.1 mm deep — a standard 3-pole MCCB form factor that drops into most SENTRON or third-party distribution blocks without panel rework. If your BOM calls for shunt trip or remote signaling, you need a different variant in the 3VA family.
