BQD220 – SIEMENS 2P20A 277V BOLT ON 14kA BREAKER
The BQD220 is a reliable Siemens 2P 20A 277V bolt-on circuit breaker designed for superior protection in electrical systems. With a robust 14kA interrupting capacity, it ensures reliable performance during fault conditions. Ideal for commercial or industrial applications, this breaker guarantees safety and efficiency in your electrical setup.
The BQD220 is rated 2-pole, 20A, 277V AC with a 14kA interrupting capacity. The 277V rating is specifically designed for single-phase branch circuits on 480Y/277V wye distribution systems — commonly used for commercial fluorescent or LED lighting loads in Canada.
The BQD series has become increasingly difficult to find through standard supply channels. Northern Breaker Group specialises in obsolete and hard-to-find breakers, so we can often source the BQD220 from verified surplus and refurbished stock. Contact any of our Calgary, Edmonton, or Vancouver counters for availability and a quote.
No — the BQD220 is a bolt-on breaker and is not mechanically or electrically interchangeable with Siemens plug-in (QP/QT) breakers. Additionally, its 277V rating differs from the 120/240V rating of typical residential plug-in units. A direct BQD-series replacement is required to maintain proper fit, rating, and code compliance.
