This SENTRON 3VA1180-4ED22-0AA0 is a 2-pole molded case circuit breaker built for line protection, meaning it sits at the incoming feed to protect the entire downstream panel, not a single branch. The TM210 thermal-magnetic trip unit gives you fixed thermal and magnetic settings — no field adjustment, no configuration risk, just install and trust the curve. Rated 80 A continuous at 40 °C, it holds that same 80 A all the way up to 50 °C ambient; above that it starts a gentle derate — 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, 74 A at 70 °C.
Breaking capacity — what it clears
At 240 V AC this breaker interrupts 121 kA; at 415 V AC it still clears 75.6 kA. For DC applications, rated operating voltage is 250 V DC; the manufacturer notes that switching power values in DC networks require consulting the 3VA device manual for specific coordination.
Footprint and panel fit
Depth is 70 mm, height 130 mm.
