Protection Relays & Controls Generator & Single-Function Protection–Voltage G3300 Series Voltage Relay Description The G3300 Voltage Relay monitors voltage on generators, busbars or other distribution systems. The relay provides “undervoltage” and “overvoltage”, time delayed, and two individual output relays—one for each function. Basic adjustments can be done on the dials on the front panels. More configuration options are available through PC configuration via the optional G0100 programming Kit. PC programming enables the user to extend the ranges on the dials on the front panel. One version covers all system voltages from 63 Vac to 690 Vac. Rated voltage can be adjusted by a preset button or PC configuration. Auxiliary supply voltage is 24 Vdc.
