Description
The fully self-contained KCG591E provides precision protection against malfunction and human and operational hazards under loss of mains conditions.

The DIN rail mounted digitally controlled unit meets the protection requirements for generators connected to mains supply, such as defined in the G59/3 and similar recommendations.

Less wiring, no extra modules. Operating mode is selected by simple auxiliary contacts on the generator breaker and on the mains breaker. LEDs and open collector outputs indicate operating mode and "First Up" cause of trip.

State-of-the-art digital technology throughout, with quartz-controlled Loss of Mains detection. True RMS measurements.

Loss of Mains Protection
KCG591E will provide the following protection:
  • 2 stage Over and Under Voltage
  • 2 stage Over and Under Frequency
  • Rate of Change of Frequency (ROCOF, df/dt)
  • Vector Shift (step phase angle)

Note:
The KCG59x accommodates the new DCode Review Panel's proposal for Vector Shift immunity up to 50°. Enhanced ROCOF protection now provides adjustable averaging filter and 500ms delay for full compliance with G59/3 Amendment 3 due to come into effect on 1st February 2018.
