What you're looking at
This is a Siemens SENTRON 3VA1080-2ED46-0AA0 molded case circuit breaker — 4-pole, 80 A continuous rating, with a TM210 thermal-magnetic trip unit. It's line protection only, no ground-fault monitoring, no communication module, no motor drive add-on. The front face carries IP40 protection, so it's fine inside a panel but not for washdown areas. The 80 A rating holds at 45 °C and 50 °C; it derates to 74 A at 70 °C. That thermal curve matters if you're packing this into a hot enclosure — the 6 A drop between 50 °C and 70 °C is real headroom you lose.
Breaking capacity — what it handles
This MCCB clears 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. The 52.5 kA figure at 240 V is the headline — that's a high fault-current rating for a 4-pole frame this size, meaning it can sit downstream of a large transformer without needing a current-limiting fuse ahead of it. At 690 V the 7.5 kA still covers most industrial motor branch circuits. Rated insulation voltage is 800 V, and max DC operational voltage is 600 V — so it's also usable on DC distribution if you follow the 3VA DC application manual for the specific switching power values.
Fit and footprint
Dimensions: 130 mm tall, 101.6 mm wide, 70 mm deep. Power loss is 19.2 W maximum at rated current. That's moderate for an 80 A 4-pole — factor it into your enclosure thermal calc if you're stacking several breakers side by side.
