KCG591E — LOSS OF MAINS PROTECTION RELAY — SINGLE PHASE 2-WIRE SYSTEM All-in-one unit, the COMPLETE solution G59/3 Loss of Mains Protection Adjustable Supervision Delay Cause of Trip LEDs and Event Log Digitally Controlled Operation Tamper Proof configuration via the HHP1/HHP2 or via PC (HHP2 only) 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)
