Why Choose URC Retrofit Kits?
Comprehensive Solutions for Every Application
Every kit includes an instruction manual that clearly outlines all the steps necessary to complete the installation. The manuals contain detailed drawings and photos for clarity. We also provide templates to simplify finding the location of holes that may need to be drilled in the breaker. Based on the trip unit that was previously installed on the breaker, we will also provide extra copper if needed. AC-PRO® and ZERO-Hertz® kits come with all the details and parts that you will need to complete the retrofit. You just need to supply us with the nameplate data and any trip units or accessories installed on the breaker.
Most kits come with your choice of resets, Manual, Auto Mechanical or Electrical. The Manual Reset requires that maintenance personnel go to the breaker and manually reset the actuator before the breaker and can be closed. (When properly installed the breaker will be trip free until the actuator is reset). The Auto Mechanical actuator uses a linkage to capture some of the extra physical energy from the opening breaker to reset the actuator. This actuator is reset and ready to go as soon as the breaker opens. The electrical reset actuator is electrically operated and does not reset until activated, which can be done on the breaker or remotely through communications options.
Every kit has been installed and tested in our facility prior to production. We have thousands of kit designs in stock with more added daily.
