BQD115 – SIEMENS 1P15A 277V BOLT ON 14kA BREAKER
The BQD115 – Siemens 1P15A 277V Bolt On Circuit Breaker is designed for reliable performance with a 14kA interrupting capacity. This single pole breaker ensures optimal protection for your electrical systems while offering easy installation. Ideal for commercial and residential applications, it’s perfect for enhancing your circuit protection needs.
277V is the phase-to-neutral voltage of a 480/277V three-phase wye distribution system, commonly found in commercial buildings. The BQD115 is typically used to protect single-phase 277V fluorescent or LED lighting circuits in offices, warehouses, and retail spaces — it is not intended for standard 120/240V residential wiring.
While the BQD, BL, and BA series are all Siemens bolt-on style breakers, they are not necessarily interchangeable. The BQD series is specifically rated for 277V/480V applications, whereas BL/BA breakers are typically rated for 120/240V. Always verify the voltage rating and panel compatibility before substituting one series for another. Contact us and we'll help confirm the correct replacement.
Availability of the BQD series can vary. Northern Breaker Group specializes in obsolete and hard-to-find breakers and maintains stock across our Calgary, Edmonton, and Vancouver locations. Even if the BQD115 is discontinued or allocation-limited, we can often source new, reconditioned, or surplus units. Request a quote and our team will check current inventory for you.
