SENTRON 3VA1080-2ED36-0AH0 MCCB — 80 A, 52.5 kA SCCR, TM210 Release
It carries a continuous current rating of 80 A at 40 °C, with a thermal-magnetic TM210 release that provides fixed thermal and adjustable magnetic trip thresholds — the 210 designation means the magnetic pickup is set to 10x In (800 A), which is typical for feeder or branch-circuit protection against moderate inrush without nuisance tripping. The interrupting rating climbs to 52.5 kA at 240 V AC and still holds 32 kA at 415 V, dropping to 7.5 kA at 690 V, so it fits 400 V class panels with high available fault current. Insulation voltage rated at 800 V gives headroom for the 690 V working level.
The interrupting rating drops as system voltage rises: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500 V and 690 V. Thermal derating is mild: rated 80 A from 40 °C through 50 °C, then 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. In a crowded enclosure running at 60 °C ambient, you lose only 3 A — still 77 A continuous. The TM210 release's magnetic trip at 800 A means it clears fast on bolted faults but lets through motor-start or capacitor inrush up to that level without tripping.
Mounts on a standard DIN rail or panel-mount base; the 3-pole footprint is 76.2 mm wide (3 inches), 130 mm tall, 70 mm deep — fits a standard MCCB slot in most distribution boards. A trip indicator is built in — visible flag on the front shows tripped vs ON/OFF without needing to read the handle position.
