The is designed for performingsecondary injection testingof the Static Trip III (STIII) overcurrent tripping system utilized on the RL breaker. The system is packaged in a self-contained case and requires 120VAC to operate.
The contains a microprocessor controlled constant current source which enables rapid verification of the performance of the STIII.
The desired test current may be directly entered with a numeric keypad for ease of test configuration. The self-contained, automatically controlled digital timer allows simple verification of the time-current tripping characteristics. Thealso provides a regulated DC voltage to allow functional testing of the tripping actuator.
