KUMSUNG ELECTRIC Co., Ltd.

Surge protector (Din-rail type)
Kumsung SPD Series Surge Protector is used for power supply of low-voltage incoming panel lead-in and can be used in places with a high number of lightning strikes where it is hard to disperse the lightning strikes.

Features: Our Class ll Din-rail Surge Protector protects the power of devices or facilities from lightning surge and switching surge of an electrical system 220V/380V, low-voltage AC 50/60Hz.

MoV (metal oxide varistor) and GDT are built-in to prevent a fire on the surge protector when a leakage current increases by flames from lightning strikes.

The MOV is provided in a plug-in type, which is economic and good for maintenance (convenience) and installation in a small space.

The module-form protector shows green for normality and red for failure.

Usage

Protection for various power lines of distribution boards and panel boards
Protection for power supply of various devices and electronics
Compact-size good for installation in a small space
Easy maintenance and cost reduction (attached to rail)
Display window to show the operation status
Combined protection unit structure for enhanced performance
