What this 3VA1080-4ED32-0HA0 brings to the panel
The interrupting ratings tell you where it fits: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. That high 121 kA at 240 V means it can sit upstream of a large transformer or service entrance where fault current is brutal — it won't blow apart or arc over on a hard bolted fault. The 75.6 kA at 415 V covers most European industrial distribution panels without needing a current-limiting fuse ahead of it. Thermal derating is honest: it holds the full 80 A from 40 °C up to 50 °C, then drops to 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. If your panel runs hot — say, a packed enclosure near a furnace line — you still get 72 A out of it at 70 °C, which is better than many breakers that crater above 60 °C.
Panel fit and integration
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — it's a compact 3-pole MCCB that fits standard SENTRON mounting plates and busbar systems. The 76.2 mm width matches the standard 3-pole MCCB footprint on a DIN rail or screw-mount plate, so it drops into an existing SENTRON panel without re-drilling or custom buswork. Rated insulation voltage is 800 V, and it carries a shunt trip (STL) as the auxiliary release design — that's the coil that lets a remote signal (E-stop, fire alarm, PLC) trip the breaker electrically. There's no undervoltage release, no auxiliary contacts, no ground fault monitoring, and no communication module on this variant. If you need those, you're looking at a different 3VA suffix. The front protection is IP40, so it's fine for a clean indoor panel but not for washdown areas.
What the TM210 release and ratings mean for your coordination study
TM210 thermal-magnetic release with fixed thermal pickup at 80 A. Magnetic trip set at 10x In (800 A) for short-circuit protection.
