Characteristic
◆ This type fault indicator applicable to Cable Distribution Box, Switch Cabinet, Ring Main Unit. It’s used to detect the short circuit and earth fault. ◆ Indicator advanced embedded microchips, the advantages of this fault indicator is intelligent and low power consumption. There is one switch and two indicator lights on the surface of the fault indicator. In the middle of two lights is the photosensitive switch, green light on is normal condition, red light on is fault condition. ◆ When the line short circuit or earth fault occur, the fault indicator will detection and memory the fault condition, the red light flashes by light and the red light off without light within the automatic reset time. The fault recording will be deleted beyond the automatic reset time.
