The BQ3B020H is a high-performance Siemens 3-pole circuit breaker designed for 20A operations at 240V. With a robust 22kA interrupting capacity, it provides reliable protection for your electrical systems. Perfect for both commercial and residential applications, this bolt-on breaker ensures safety and efficiency in your power distribution setup.
The BQ series uses a bolt-on mounting method, where the breaker is physically bolted to the bus bar for a more secure, vibration-resistant connection — common in commercial and light industrial panelboards. The QP series uses a plug-in design typical of residential loadcentres. The two types are not interchangeable, so it's important to confirm which style your panel requires before purchasing.
The BQ3B020H is a branch circuit breaker rated at 20A/240V with a 22kA interrupting capacity. While it can serve as a main disconnect in some smaller panelboard configurations where the ratings align, it is most commonly used as a branch or feeder breaker. We recommend consulting your panel documentation or a licensed electrician to confirm the appropriate application for your installation.
Northern Breaker Group specializes in both current-production and hard-to-find or obsolete Siemens breakers. The BQ3B020H may have limited availability depending on current stock levels. Contact our Calgary, Edmonton, or Vancouver counter for availability, and we'll source it for you — even if it's been discontinued by the manufacturer.
