The BQ1B015 Siemens 1P15A 120V Bolt-On Circuit Breaker offers reliable protection for your electrical systems with a 10kA interruption rating. Designed for easy installation, this breaker is perfect for residential and commercial applications. Ensure safety and efficiency in your circuits with this durable, high-performance component from Siemens.
The BQ series uses a bolt-on connection to the bus bar, whereas the QP/QT series use a plug-in clip. These two mounting styles are not interchangeable. You must confirm your panelboard accepts bolt-on BQ/BA-type breakers before ordering. If you're unsure, send us your panel model and we can help verify the correct fit.
The Siemens BQ series has seen limited availability in recent years, and certain configurations can be difficult to source through standard distribution channels. Northern Breaker Group specializes in hard-to-find and obsolete breakers — contact us for current stock availability and lead times on the BQ1B015.
No — the BQ1B015 is a standard single-pole, full-size bolt-on breaker and is not a tandem (half-size) device. If you need to add circuits to a full bolt-on panel, you would require a specifically rated tandem bolt-on breaker that your panelboard supports. Contact us and we can help identify the right solution for your panel.
