BQ2B0100– SIEMENS 2P100A 240V BOLT ON 10kA BREAKER
The Siemens BQ2B0100 is a reliable 2-pole, 100A, 240V bolt-on circuit breaker designed for high performance in residential and commercial applications. With a fault current rating of 10kA, it ensures robust protection against overloads and short circuits. Ideal for new installations or replacements, it guarantees safety and efficiency in your electrical system.
Bolt-on breakers like the BQ2B0100 are mechanically fastened to the bus bar with a screw or clip, providing a more secure connection than plug-in breakers. They are not physically interchangeable with plug-in style breakers, so your panel must specifically require a bolt-on type. Check your panel's label or directory for the approved breaker type, or send us your panel model and we'll help you confirm the right fit.
The BQ series has seen limited availability through standard distribution channels, making the BQ2B0100 a breaker we frequently source for customers with older or legacy Siemens/ITE bolt-on panels. Northern Breaker Group specializes in obsolete and hard-to-find breakers — contact us for current stock availability and lead times.
Yes — a 2-pole 100A bolt-on breaker like the BQ2B0100 is commonly used as the main breaker in a 100A sub-panel, provided the panelboard is rated for 100A and is listed for use with BQ-series bolt-on breakers. Always verify the sub-panel's approved breaker list and ensure the installation meets CEC (Canadian Electrical Code) requirements. Our team is happy to assist — reach out with your panel details.
