The line fault detector, as a device to monitor the open/short circuit of the cable of emergency system, is a alarm device to display the information of open/short circuit on it and to send the dry-contact signal output to external system in case the open/short circuit of the cable of the switching system occurs.
As special features, the exterior materials have high insulation level, light weight, fire retardant, shock resistant and chemical resistant characteristics to endure the harsh environment such as shipyard, power plant, steelworks, petrochemical complex and water power plant etc..
