Features:
• This is a kind of fine quality surge protecting device, fire proof and corrosion-resistant. Quickly react speed with strong bearing capacity.
• Simple and easy to use. More reliable and more safety.
• Working status indicating window, red means failure, which can effectively react the working status in time.
• Surge protect, prevents home electric network receive excessive impact while lightening.
• Detachable 35mm Din rail installation design.
Application:
• Protects electrical installations against direct lightning strokes, and discharge the back-current from lightning spreading from the earth conductor to the network conductors.
• Used to AC power system, power distribution system, terminal devices, electronic equipment, buildings, industrial enterprises and Medical institutes etc.
Installation:
Type 1 or Type 1+2 SPD (Iimp ≥ 12.5 kA) compulsory at the installation source (main distribution board in secondary buildings).
Installations more than 10 m high (apartment buildings, office buildings, hotels, etc.): type 2 SPD recommended for protecting private areas and floor distributors (communal areas) in addition to a type 1 or type 1+2 SPDs.
