The Siemens SENTRON 3VA1080-3ED36-0AF0 is a 3-pole molded case circuit breaker rated 80 A continuous at 40 °C, with a TM210 thermal-magnetic release tuned for line protection — no ground-fault monitoring, no undervoltage release, no communication module. The interrupting ratings climb to 75.6 kA at 240 V, drop to 52.5 kA at 415 V, then 32 kA at 440 V, and settle at 7.5 kA at both 500 V and 690 V. That 7.5 kA floor at 690 V tells you this is a 480 V-class MCCB that can handle 600 V-class systems only where the available fault current is low — coordination studies need that number. The 70 mm depth and 76.2 mm width fit the standard SENTRON 3VA footprint; it mounts on a DIN rail or panel base, so it drops into existing 3VA panel layouts without re-drilling.
Thermal derating and the TM210 release
At 55 °C it derates to 78 A, at 60 °C to 77 A, at 65 °C to 75 A, and at 70 °C to 74 A. That simplifies spares — one part number, one setting. Maximum power loss is 19.2 W, which matters for heat buildup in a dense panel.
