Product Details

7KA Lightning arrester Type 1+2 SPD Ac Surge Protection Device IEC 61643-11

7KA Lightning arrester Type 1+2 SPD Ac Surge Protection Description:

• The lightning arrester BR-7M 2P meets the type 1+2 requirement class according to IEC 61643-11.

• Low voltage protection level.

• The use of high-performance varistors permits a rapid response time and a low protection level, without any line follow current.

• DIN-rail mounting configuration.

• If circumstances are uncertain and there is a risk of fire from an overload, the internal cut-off unit disconnects the arrestor from the mains if necessary.
