MULTI FUNCTION GROUND FAULT 

RELAY [GFR]-5C, 10C

Features

Rating & Specification

1. Multi-ground fault relay(GFR) is multi-functional and is able to detect multiple ground faults of monitoring circuit and is displayed 
   leakage in the circuit and fault current when earthing.
2. It is installed 8 bit MCU with A/D conventer and is configured to perform advanced functions for high relability.
3. It is a collective device that is intergrated many ground fault detector of conventional single unit.
4. It is capable to detect from minor grounding fault current(0.1A) to medium level fault current (10A)
5. It is configured to have operating time taps for adjustment of time setting is easy for protection coordination of distribution circuit
6. As wide display and indicators, it is able to enhance checking up and performance.
7. Watch dog function assures error - free operation.
8. The memory stores the last record of ground fault current of each circuit to facilitate following up in the event of accidents.
9. The ABS casing newly adopted offers improved durability and extended life of product.
10. All GFRs are tested EMC to ensures and high frequency & surge do not interfere design performance of GFR.
