3VA4180-4ED34-0AA0 - 80Amp Circuit Breaker

3VA4180-4ED34-0AA0  -  80Amp Circuit Breaker

The Siemens 3VA4180-4ED34-0AA0 is one of those breakers you install and don’t have to think about again. It’s part of the SENTRON 3VA4 line, built for straightforward circuit protection in commercial and industrial setups where things just need to work—day in, day out. This is an 80 amp, 3-pole molded case circuit breaker with a thermal-magnetic trip unit, so it covers both overloads and short circuits without any unnecessary complexity. Under normal conditions, it stays out of the way. But when there’s a fault, it reacts fast—tripping instantly at 10 times the rated current to help limit damage to your system. With a 25kA interrupting rating at 480V, it’s well-suited for typical distribution panels, machinery, and HVAC equipment. It’s also compact enough to fit where space is tight, which is always a plus when you’re working inside a crowded panel.
