The Siemens 3VA4110-4ED34-3AA0 is a 3-pole molded-case circuit breaker from the 3VA4 series, built on a UL Frame 125 platform. The breaking capacity lands at 25 kA at 480 V AC — class S in Siemens' 3VA4 lineup, sized for commercial and light industrial distribution panels where fault currents stay under that threshold. This breaker uses a TM210 trip unit — thermal-magnetic, line protection, no electronic adjustment. The overload and short-circuit settings are factory-fixed, so it's a straight swap-in for a BOM that already calls for 100 A fixed protection. No dials, no plug-in modules; the Ir and Ii are what they are.
The 3-pole block occupies roughly 108 mm of DIN width (6 modules). Line and load lugs accept copper or aluminum conductors up to the frame rating.
