The BQ2B0100H Siemens 2P100A 240V Bolt-On Breaker is designed for reliability and safety in your electrical systems. With a robust 22kA breaking capacity, this circuit breaker efficiently protects against overloads and short circuits. Ideal for residential and commercial applications, it ensures optimal performance and peace of mind in every use.
The BQ (BL/BA) series uses a bolt-on connection to the bus bar, providing a more secure mechanical and electrical connection — commonly specified in commercial panelboards or residential loadcentres designed for bolt-on breakers. The QP series is a plug-in design for different Siemens loadcentres. The two styles are not interchangeable, so always confirm your panel's bus type before selecting a replacement.
The Siemens BQ series has seen limited availability through standard distribution channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers across Canada, and we maintain stock or can source the BQ2B0100H for you. Contact our Calgary, Edmonton, or Vancouver counters or request a quote online.
The 22kA AIC (Ampere Interrupting Capacity) rating is suitable for most residential and light commercial services in Canada, where available fault current is typically below this threshold. However, the Canadian Electrical Code (CEC) requires that the breaker's interrupting rating meet or exceed the available fault current at the point of installation. We recommend confirming the available fault current with your electrician or utility before installation.
