The BQ2B015H Siemens 2P15A 240V Bolt-On Breaker is designed for optimal circuit protection with a high interrupting rating of 22kA. This durable and reliable two-pole breaker is ideal for residential and commercial applications, ensuring your electrical systems remain safe and efficient. Upgrade your electrical panel with this essential component.
No, they are not interchangeable. The BQ series uses a bolt-on mounting that secures directly to the bus bar with a fastener, while QP/QT breakers use a plug-in clip design. Your loadcentre or panelboard must specifically accept bolt-on style breakers. Check your panel's label or send us the model number and we'll confirm compatibility.
The 22kA interrupting rating means this breaker can safely interrupt fault currents up to 22,000 amperes at 240V. For most residential and light commercial services in Canada, this exceeds typical available fault current. However, if your application requires a higher AIC rating (e.g., 42kA or 65kA for commercial switchboards), a different breaker would be needed — contact us and we can help you select the right unit.
Siemens has transitioned some BQ series SKUs over time, and availability can vary. Northern Breaker Group specializes in obsolete and hard-to-find breakers, maintaining stock of legacy Siemens bolt-on units. If the BQ2B015H is no longer available through standard distribution channels, we can source it or identify a compatible alternative — reach out to our Calgary, Edmonton, or Vancouver counters for a quote.
