The Siemens SENTRON 3VA1080-2ED42-0BA0 is a 4-pole molded case circuit breaker (MCCB) rated for 80 A continuous at 40 °C, built around the TM210 thermal-magnetic trip unit. Interrupting capacity is voltage-dependent: 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. That's enough for most industrial distribution panels fed from a 500 kVA transformer — the 415 V figure covers the common European 400 V grid with headroom.
Above that it steps down: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. Dimensions are 130 mm tall, 101.6 mm wide, 70 mm deep — a standard SENTRON 3VA frame footprint. The 4-pole width (101.6 mm) means it occupies the same slot as other 4-pole 3VA breakers; swapping from a 3VA1010 frame is a direct mechanical fit.
