AC-PRO^® End-Of-Life Announcement

Due to component obsolescence and limited availability, we regret to inform you that after more than 26 years, our original AC-PRO^® trip unit is approaching end of life.

We estimate that we will no longer be able to supply AC-PRO^® trip units starting on July 31, 2023.

While the majority of our customers have already made the switch to AC-PRO-II^® over recent years, we do realize this will be an inconvenience for some. We will work to support you as well as possible during this period of transition and moving forward.

Additionally, please note the following:

• This end-of-life announcement only applies to our original AC-PRO^® trip unit, commonly referred to as AC-PRO-I. It does not apply to any other units.
• The end-of-life date of July 31, 2023 is an estimate and could vary slightly.
• As the end-of-life date approaches, lead times for AC-PRO^® may be negatively impacted.
• There will be no change to AC-PRO^® warranty coverage and support.
• Out of warranty AC-PRO^® units will still be supported but repair capabilities may become limited.
• If you are unfamiliar with AC-PRO-II^® or would like to learn more about its features and benefits, training is available. Simply reach out to your URC Sales Engineer to arrange.

Our original AC-PRO^® trip unit has the honorable designation of having the longest production run of any low-voltage trip unit in history. We have produced AC-PRO-I trip units for nearly 27 years and it would have been even longer if it weren’t for situations outside of our control. We are extremely grateful to our many customers who have been longtime AC-PRO^® users – many of whom have been users since the very beginning.

While we are putting AC-PRO-I behind us, we are excited to continue providing superior solutions for your electrical protection needs. Our flagship trip unit, AC-PRO-II^®, along with AC-PRO-MP^®, ZERO-Hertz^®, and the recently launched AC-PRO-NW^®, all lead the industry with innovative features and untouchable service, delivering the functionality you need when you need it.

Here’s to the next 26 years!
