The Siemens 3VA4180-4ED34-3AA0 is a 3-pole molded case circuit breaker from the 3VA4 series, built on a UL Frame 125 platform. It is rated for line protection with a fixed TM210 thermal-magnetic trip unit set at 80 A (Ir = 80 A permanently set) and a short-circuit pickup of Ii = 10 x In. The breaking capacity class S delivers 25 kA at 480 V, which means it can safely interrupt faults up to that level on a 480 V distribution bus without cascading upstream — a key selectivity figure when coordinating with downstream branch breakers.
