The Siemens HGB3K020B is a 3-pole, 20A, 600V plug-in (push-in) molded-case breaker from the Siemens HGB frame/series. As a 600V-rated, 3-pole MCCB with a 14kA interrupt rating, this breaker is designed for installation in compatible Siemens/ITE commercial panelboards and switchboards that accept the HGB plug-in frame — not for standard residential loadcentres. It is not interchangeable with QP/BL/BA residential plug-on breakers.
Panel and bus compatibility depends on your specific switchboard or panelboard model. Send us your panel model and we'll confirm fitment.

Northern Breaker Group specializes in exactly these hard-to-find breakers — reach out to our Calgary, Edmonton, or Vancouver counter for current availability.
Yes — with its 3-pole configuration and 600V rating, the HGB3K020B is well suited to 3-phase, 600V systems common in Canadian commercial and light industrial applications. Always verify that the 14kA interrupt rating meets or exceeds the available fault current at the installation point, as required by the Canadian Electrical Code (CEC).
