Surge Protector

Wire-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.

Wire Type

Product description
The wire-type surge protectors are available in various
sizes and capacities.
The products integrate a disconnector, which includes a
protection device, and a functional circuit, which shows
whether the protection device works normally or not,
in a steel case.
The protectors are used to protect the incoming power
supply of incoming and distribution boards of electric
systems that use low voltage AC of 50/60 Hz and 220 V
/ 380 V from the lighting-induced surge, the surge from
switching, as well as the surge from overvoltage.
Configured in parallel, they can be maintained easily.
