What it is and what it does
The Siemens 3VA4130-4ED24-3AA0 is a 2-pole molded case circuit breaker from the 3VA4 series, Frame 125, rated for line protection. It carries a fixed 30 A overload setting (Ir = 30 A) via the TM210 thermal-magnetic trip unit and a short-circuit pickup (Ii) fixed at 10 × In, or 300 A. The interrupting rating is 25 kA at 480 V, placing it in breaking capacity class S — sufficient for most commercial and light industrial panelboard applications where fault currents stay under that threshold.
