Siemens HFD63B125 is a molded case circuit breaker from the Sentron Series designed to provide reliable thermal-magnetic protection for three-phase industrial power distribution systems. It features a 125A current rating and a 600V AC voltage rating, housed within a compact FD frame measuring 5.906" W x 9.843" H x 6.693" D and weighing 8.576 lb. The breaker is constructed for operation in temperatures from -25°C to 70°C and complies with industry standards for integration into various panel types including S4, P4, SPP, and F-series enclosures. Its 65kA interrupting capacity at 480V makes it suitable for protecting feeders and branch circuits in commercial and industrial facilities, supporting copper wire from AWG 6 to 350 KCMIL and aluminum from AWG 4 to 350 KCMIL with its bolt-on connection (note: lugs are not included).
