scope of application

Decoupler is an auxiliary device of lightning protection device, suitable for the line length between the front and rear stages of surge protector less than 10 meters (between switch type and voltage limiting type) or less than 5 meters (between voltage limiting type).

Use installation

The decoupler is installed and fixed with a 35mm standard guide rail, and the wiring method is shown in the figure. The L1 and L1 'points are connected in series between the wires connecting the two stages of SPD. According to the function of the decoupling device, it should be installed near the front stage surge protector.

precautions

The cross-sectional area of the wire connecting the 35A decoupling device should be greater than 6mm ²

The cross-sectional area of the wire connecting the 63A decoupler should be greater than 16mm ²
