Product Features:
combination type SPD
The smallest size single phase surge protector of Iimp: 50KA ;
only 27mm width, save space;
Sealed metal air gap technology,high energy electronic trigger discharge gap, with the ability to block continuous flow
Low output residual;
fast response time (≤25ns);
◆ The product is installed at the junction of LpZ0A or PLZ0B and PLZ1 area.or installed on the 35mm standard rail at the main distribution box(cabinet) of the power supply. The connecting rall adopts a 6-35mm² multi-strand copper cord.
◆The grounding wire should be a two-color wire of 16mm² or more, and the length is not more than 500mm.
◆In order to prevent the safety of the grid from being affected after the failure of the eddy current protector,a protective HDSCB backup protector should be connected in series with the protection.
Main structure and working principle
◆ spD is a-port, anti-shock protection, indoor fixed installation, voltage limited type.
◆With high impact current (imp: 15kA). Features such as low residual pressure (Up: ≤ 1.5kV). SPD has a built-in disconnector, When the SPD fails due to overheating and breakdown. the disconnector can automaticaly disconnect it from the arid. At the same time, an indication signal is given. ◆The visible window displays white when the SPD is working normally, and displays red after falilure and separation.
