The T2200 Overcurrent Relay is designed for generator or feeder protection against overcurrent in each of the three phases. The T2200 detects the highest of the 3 input currents and, if this exceeds the preset level (0.5 - 1.4 x IN), the pick-up LED will indicate and the delay timer will be started. After the preset time (3-30 sec.) has expired, the output relay and the corresponding LED will be activated, provided that the current level was exceeded for the entire delay time.
