BQ2B050H– SIEMENS 2P50A 240V BOLT ON 22kA BREAKER
The BQ2B050H SIEMENS 2P50A 240V Bolt On Breaker provides reliable protection with a robust 22kA interrupting capacity. Designed for high-performance applications, this dual-pole circuit breaker ensures efficient operation and safety in electrical systems. Ideal for both residential and commercial use, it fits seamlessly into your circuit integration needs.
The BQ series uses a bolt-on bus connection, where the breaker is physically bolted to the panel busbar rather than snapping onto it. This provides a more secure, vibration-resistant connection often required in commercial or industrial panelboards. A QP plug-in breaker cannot be substituted in a bolt-on panel space, and vice versa — always match the breaker type to your panel's bus design.
Yes. The BQ2B050H is a 2-pole breaker rated at 240V and 50A, making it well-suited for double-pole applications like electric ranges, dryers, EV chargers, hot tubs, or feeding a sub-panel — provided the wiring gauge and panel rating support the load. Always consult a licensed electrician to ensure compliance with the Canadian Electrical Code (CEC).
