Reviews Summary
Customers say these circuit breakers arrive quickly and work as expected. Many reviews mention fast shipping, with some receiving orders overnight or within days. Users report the breakers fit properly, install easily, and function correctly in both residential and commercial applications. Common feedback includes competitive pricing and good packaging that protects products during shipping. While most praise the ordering process as straightforward, some note occasional issues with missing installation screws or receiving updated product versions instead of pictured models. Several contractors and electricians appreciate having access to hard-to-find or obsolete breakers when local suppliers lack inventory.

    Excellent Service

    SuperBreakers shipped exactly what we ordered. We signed up for expedited delivery and received the shipment with enough time to install the breaker and power up equipment before the project was to be commissioned. We will definitely be using SuperBreakers again. Thank you so much for helping our team complete another successful project.

    The breaker came overnight. I didn't pay for extra shipping either. It was helpful because I was able to get the job done without making a special trip.

    The item arrived quickly, was well packaged, and worked perfectly as expected.

    Installation was easy, and the breaker fits well and saves space with its duplex design.
