The BQD360 – SIEMENS 3P60A 480V Bolt On Breaker provides dependable circuit protection with a 14kA interrupting capacity. Designed for three-phase applications, this robust breaker ensures optimal performance and safety for your electrical systems. Perfect for commercial setups, it offers easy installation and reliable operation to keep your equipment secure.
The BQD360 is a bolt-on MCCB designed for Siemens/ITE commercial panelboards and switchboards that accept BQD-frame bolt-on breakers. Because compatibility depends on the specific bus arrangement and available breaker spaces in your enclosure, we recommend sending us your panelboard model number so our team can confirm the fit before you order.
At 14 kA (480 V), the BQD360 is suitable for many commercial branch and feeder circuits where available fault current has been confirmed at or below that level. If your service entrance or upstream source could produce higher fault currents, you may need a higher-interrupting-capacity frame. We can help you select the right breaker once you provide your system's available fault current (AIC) from your engineer or utility.
The BQD series is considered a hard-to-find frame in Canada. Northern Breaker Group specialises in obsolete and difficult-to-source breakers and maintains stock of legacy Siemens/ITE commercial MCCBs.
