BQ3B060– SIEMENS 3P60A 240V BOLT ON 10kA BREAKER
The BQ3B060 SIEMENS 3P60A 240V Bolt-On Breaker is designed for reliable performance in residential and commercial applications. With a 10kA interrupting capacity, this three-pole circuit breaker offers robust protection against overloads and short circuits. Ideal for your electrical setup, it ensures safe and efficient operation for your devices.
The BQ3B series uses a bolt-on mounting design, meaning the breaker is mechanically fastened to the bus bar with a bolt rather than clipping in. This provides a more secure connection and is required by certain Siemens/ITE panelboards — particularly in commercial or higher-vibration applications. It is not a drop-in replacement for plug-in style breakers even if the amperage and poles match.
The BQ3B frame has been discontinued by Siemens, making the BQ3B060 a hard-to-find breaker. Northern Breaker Group specializes in sourcing obsolete and legacy Siemens breakers — contact us for current stock availability and lead time.
Yes — the BQ3B060's 3-pole, 60A, 240V rating makes it suitable for feeding a sub-panel or protecting large three-phase-wired loads in compatible installations. Always verify the 10kA interrupting capacity meets the available fault current at the point of installation, and consult a licensed electrician to ensure compliance with the Canadian Electrical Code (CEC).
