The Siemens HGB3K050B is a 3-pole, 50A, 600V plug-in (push-in) molded-case circuit breaker in the HGB frame series. With a 14kA interrupting rating at 600V, it is designed for use in Siemens/ITE commercial panelboards and switchboards that accept HGB-frame plug-in breakers — typically three-phase distribution panels rather than residential loadcentres. It is not a drop-in replacement for residential QP/BL-series breakers.
Panel compatibility depends on your specific panelboard's bus rating and frame acceptance. Send us your panel model number and we'll confirm fitment.
The HGB frame is a commercial/industrial molded-case series designed for Siemens three-phase panelboards and switchboards that support HGB-frame plug-in breakers. It is not intended for residential EQ or PL loadcentres. Send us your panelboard model and we can confirm whether the HGB3K050B is a compatible fit.
Yes. The HGB3K050B is rated 600V, which aligns with Canada's standard three-phase distribution voltage, making it well-suited for Canadian commercial and industrial applications. Its 14kA interrupting rating must be verified against the available fault current at the point of installation to ensure code compliance.
