The Siemens 3VA4125-5ED24-3AA0 is a 2-pole molded case circuit breaker from the 3VA4 series, built on a UL Frame 125 platform. It carries a 35 kA interrupting rating at 480 V AC (breaking capacity class M), sized for line protection in North American panelboards and downstream distribution. The TM210 thermal-magnetic trip unit is factory-set with overload protection Ir=25 A (fixed) and short-circuit protection Ii=12 x In, so no field adjustment of the trip curve is needed — it arrives ready for a 25 A branch circuit.
