ZERO-Hertz, AC-PRO-MP, AC-PRO & QUICK-TRIP and the LCISince URC started in 1995, our total energy has been focused on one thing, low voltage protection. More specifically, to develop and manufacture retrofit protection products for the low voltage breaker retrofit market. Our company philosophy is simple; produce high quality, easy to use and install products and follow it up with the greatest customer service possible.

Our first product was the ZERO-Hertz®; DC trip unit. We then moved to AC and developed the AC-PRO®; trip unit. Over the years both the ZERO-Hertz®; and AC-PRO®; trip units have become familiar names in the industry. The AC-PRO-MP®; along with other products are offshoots from the original ZERO-Hertz®; and AC-PRO®; trip units. One of our latest products is the AC-PRO-II®; which is 55% smaller than the AC-PRO®; and has additional features to make it easier to navigate, commission, and install. We sell these trip units as part of a complete retrofit kit that is engineered and designed specifically for a particular circuit breaker. Right now, we have over 4,500 different kits! And we’re still not finished!

Utility Relay Company

Over the years we have moved our operation six times. Each time we roughly doubled in square footage in an effort to stay ahead of our continued growth. In our present location we are ready for the future and have sufficient acreage for our planned expansion. However, a building is useless unless it is filled with talented, dedicated and focused people. Utility Relay definitely has that! On average, our employees have been with the company for over 6 years.

As we go through our busy days at Utility Relay Co., we never forget that we owe our success to our   dedicated employees and especially to our many loyal customers.
