Utility relay company is a leading manufacturer of microcontroller based true rms solid state trip units for ac and dc power circuit breakers.
Utility relay company ac pro 2.
Ac pro ac pro ii lt trip times.
The end result is an extensive line of retrofit kits that both provide reliable protection and are easy to install.
All shipments are fob factory.
New features with infopro ac 2 1.
Auxiliary power is optional.
Each of these protective features can be turned on or off at any time except for the long time setting.
If the mechanism operating time is excessive the ac pro ii will alarm that breaker maintenance is required.
