Description
Built for commercial applications, the Siemens HF3-B020 is a 3-pole, 20A molded case circuit breaker from the legacy HF series. It provides proven thermal-magnetic protection for distribution networks. This bolt-on unit installs into Siemens P4 and P5 panelboards, SB switchboards, and motor control centers. As a discontinued model, it serves as an exact-fit replacement, crossing over to the HFD63B020 substitute. It features a 65kAIC rating at 240VAC and fixed LI trip functions.Specifications
