LH-BD (36 width) series surge protector (hereinafter referred to as SPD)

SPD is one port, protected against electric shock, indoor fixed installation, voltage limited type.  SPD has built-in disconnector. When the SPD fails due to overheating or breakdown, the disconnector can automatically disconnect it from the power grid and give an indication signal at the same time.  The visual window displays green when the SPD is working normally, and displays red after failure. It is composed of 1P, 2P, 3P and 4P combined protection modules and is used in power supply systems such as TT and TN.

Installed at the junction of LPZ1 or LPZ2 zone and LPZ3 zone, it is installed using a 35mm standard guide rail, and the connecting copper multi-strand wire is 2.5~16mm². The grounding wire should be a two-color wire of more than 6mm², and the length should not exceed 500mm.  Each pole of SPD must be equipped with protection - SCB series surge backup protection is used for short circuit protection after SPD breakdown. It is suitable for use in front of household distribution boxes, computer equipment, information equipment, electronic equipment and control equipment or in the nearest socket box.
