The BQD215 is a Siemens 2-Pole 15 Amp, 277 Volt bolt-on circuit breaker designed for reliable performance in demanding applications. With a short-circuit interruption rating of 14kA, this breaker ensures optimal protection for your electrical system. Perfect for commercial and industrial use, it delivers robust reliability and safety.
277 volts is the phase-to-neutral voltage of a 480Y/277V three-phase commercial power system — the standard for fluorescent and LED lighting circuits, as well as some HVAC and mechanical loads in commercial and industrial buildings. The BQD215 is specifically rated for this voltage, making it a common choice for lighting panel branch circuits in offices, warehouses, and retail facilities across Canada.
The BQD series has seen limited availability through standard distribution channels. Northern Breaker Group specialises in hard-to-find and obsolete breakers, and we maintain stock of Siemens BQD breakers for exactly this reason. Contact our Calgary, Edmonton, or Vancouver counters or request a quote online — we'll confirm availability and condition promptly.
Only if the replacement amperage is appropriate for the circuit's wire gauge and load — you cannot simply swap in a different-rated breaker without verifying conductor sizing and load requirements per the Canadian Electrical Code (CEC). The BQD215 (15A) must be matched to conductors rated for at least 15A (typically 14 AWG copper or 12 AWG aluminum). Always consult a licensed electrician before substituting a different amperage breaker.
