Generator & Single-Function Protection–Overcurrent
T2200 SERIES
3-Phase Overcurrent Relay
Description
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 I
will indicate and the delay timer will be started. After the
), the pick-up LED
N
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.
