    Help with flood conditions

    The whole process with Technitrol was Awesome. Jim the owner was extremely helpful he caught some problems with one of the breakers that I didn't notice very helpful. James and Collin were great also. The whole company really step up helping me determine what path I should take to replace/refurbish breakers that went through a flood. I never experienced a flood like this they were an awesome resource and help to me and my employer the City of Wauwatosa

    Stock!

    Superbreakers has gotten my company out of a few binds recently. When stock is unavailable at my local supplier I've been turning to Superbreakers to save the day. Great customer service and timely shipments.
