Utility relay company ac pro.

Utility relay company is a leading manufacturer of microcontroller based true rms solid state trip units for ac and dc power circuit breakers. The ac pro trip unit is a solid state true rms sensing overcurrent device for use on 600 volt class circuit breakers. Utility relay company is a leading manufacturer of microcontroller based true rms solid state trip units for ac and dc power circuit breakers. The ac pro comes standard with long time short time instantaneous ground fault and phase unbalance protections.

Products ac pro ac pro. See the communication instruction manual for more information. When utility relay company designed the ac pro ii we decided to use the new enhanced version of the ul mark so we would be compliance with any future ul regulations. The end result is an extensive line of retrofit kits that both provide reliable protection and are easy to install.

Each of these protective features can be turned on or off at any time except for the long time setting. The following video shows the proper procedure to upload settings given from an older ac pro to an ac pro ii using the infopro software in place of manual entry.
