The BQD230 is a high-performance Siemens 2-pole circuit breaker rated at 30 amps and 277 volts. This bolt-on breaker features a 14kA interrupting capacity, ensuring reliable protection against overloads and short circuits. Ideal for commercial and industrial applications, it promises durability and efficiency for your electrical system needs.
The BQD230 is a bolt-on style breaker designed for Siemens commercial and industrial panelboards that accept BQD-series bolt-on breakers in a 277V/480V distribution system. It is not compatible with residential plug-in loadcentres. Send us your panel model number and we'll confirm compatibility.
The 277V rating is specifically designed for 480Y/277V wye-configured three-phase systems, which are standard in Canadian commercial buildings for lighting circuits and HVAC loads. This is not a typo — it cannot be substituted for a 120/240V-rated breaker in a residential system.
Northern Breaker Group specializes in hard-to-find and obsolete breakers, including Siemens BQD-series units. Whether the BQD230 is available new, reconditioned, or as a verified used unit will depend on current stock. Contact our Calgary, Edmonton, or Vancouver counter — or request a quote online — and we'll source it for you.
