Surge Protector

Terminal-type Surge ProtectorsThe KumSung Electric SPD series surge protectors are used for the incoming power supply for low-voltage main incoming boards. They are to be connected with large economical surge protectors through a parallel connection. They can be used in areas where lightning strikes frequently and cannot be easily distributed.

Terminal-type Surge Protectors

Main applicable areas
Main incoming and distribution boards for the input side voltage
Various electric, information, and communication systems such as UPS, CCTV, DCS, PLC, and SCADA.
VMS signboards and power service entrances
Railway, subway, broadcasting stations, and communication stations
Industrial machinery and computer panels
Traffic control centers, dams and water treatment plants
Product features
Certified for KS (qualified for IEC international standards)
High performance and large scale surge protection
Dual safety design (current and thermal fuse)
Easy maintenance due to LEDs that indicates about operation and failure
Steel case protected against the failure of surge protectors
