AC Power Low Voltage Surge Protection Device Product overview
Each front pole of SPD surge protector must be connected in series with XZSCB series surge backup protector or fuse.
The SPD has a 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. The visual window displays green when SPD is working normally, and red when it disengages.

AC Power Low Voltage Surge Protection Device Overall dimensions
The protection device shall be installed at the end of the upline (immediately connected to the downline of the pull-in wire) required to protect thecustomer's equipment, connecting the outer lead(L) or neutral lead (N) to the grounding device of the customer's equipment. It is installed at the junction of LPZOA zone and LPZ1 zone, with 35mm standard guide rail and 16-35mm2 copper multi-wire connection.
XZ1-SPD80, 100 series surge protector is suitable for low-voltage AC power distribution 50/60Hz, 230/400V and below IT, TT, TN-C, TN-S, TN-C-S and other power supply systems can be connected in parallel on the power line for equal potential when lightning strikes. Mainly used to protect low-voltage customer electrical installations from surges caused by atmospheric discharge (e.g. to indirect lightning) or other operating instantaneous overvoltages. As a single voltage limiting device. Products comply with GB18802.1,GB50057 and lEC61643-1 standards.
Usually installed in the line of low voltage main distribution cabinet, used for primary power equipment protection, often used in vulnerable to lightning outdoor power distribution cabinets,power distribution cabinets and indoor irfpa have to qualify the roof of the power distribution equipment, suitable forcivil construction, electrical, communications, road traffic, such as the petrochemical industry of power equipment protection.
