The trip unit is true rms and features a built in 3 phase ammeter and a self test feature that continuously monitors the trip unit microcontroller and the actuator connection.
All of the phase protection functions use the true rms currents including the instantaneous trip function.
Each of these protective features can be turned on or off at any time except for the long time setting.
Protrip trip units may be tested with the trip unit installed in the circuit breaker the rating plug installed in the trip unit and the breaker carrying current.
We have a full gallery of pictures that demonstrate our abilities.
All settings are programmed into the ac pro using the trip unit s membrane keypad and 16 character lcd.
Models are available for use on 60 hz 50 hz 40 hz and 25 hz systems.
In addition to repairing and refurbishing services we also offer a full range of digital rms trip units such as the utility relay ac pro digitrip series 510 610 810 910 or optim microversatrip or mvt static trip ii and static trip iii.
