The Siemens 3VA4112-5ED24-3AA0 is a 2-pole molded case circuit breaker in the 3VA4 UL Frame 125 series, rated 125 A continuous with a 35 kA interrupting capacity at 480 V. The TM210 thermal-magnetic trip unit gives fixed overload protection at 125 A (Ir = 125 A, permanently set) and a fixed short-circuit pickup at 10× In (Ii = 10 × 125 A = 1250 A), so it's a straight swap-in for a line-protection application where you don't need adjustable trip settings. This is a Class C product — manufactured or produced to order, not a stocked shelf item. That means the unit is built to your order, so the packaging dimensions (472 × 396 × 213 mm) reflect a single-piece shipment, and the part cannot be returned for credit once ordered. Plan your BOM freeze accordingly.
RoHS compliance is confirmed since May 2019.
