The Siemens BQ1B020H is a 1-pole, 20A, 120V bolt-on breaker from the Siemens BQ/BL series, designed to bolt directly into compatible Siemens/ITE bolt-on style panelboards — including select Siemens EQ, ES, PL, and PN series loadcentres and panelboards that accept bolt-on type breakers. Its 22kA interrupting rating suits both residential and light commercial installations.
Bolt-on breakers are not interchangeable with plug-in (QP/QT) style panels — ensure your panelboard specifically calls for bolt-on breakers before installing. Send us your panel model number and we'll confirm compatibility.
Bolt-on breakers like the BQ1B020H are mechanically fastened to the bus bar with a screw, providing a more secure connection — common in commercial panelboards and some residential loadcentres. Plug-in breakers simply snap onto the bus. The two styles are not interchangeable, so it's important to verify your panel requires a bolt-on type before ordering.
Siemens product availability can vary, and certain BQ-series breakers may be difficult to find through standard supply channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers across Canada — contact our Calgary, Edmonton, or Vancouver locations for availability and to request a quote.
No — the BQ1B020H is rated for 120V and is a single-pole breaker, making it suitable for 120V branch circuits only. For a 240V application, you would need a 2-pole breaker rated for 240V. Contact us and we can help identify the correct Siemens BQ-series double-pole breaker for your needs.
