XZ-SPD80/65(60)/40/20/10 Series Surge Protector
Product overview


XZ- SPD80、65(60)、40、20、10 series surge protector is suitable for low-voltage AC power distribution 50/60Hz,230/400V and belowIT, 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 in line with GB 18802.1, GB50057 and IEC/EN61643- 11 standards.

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.

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 the customer'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 LPZOB/LPZ1 and LPZ2 with 35mm standard guide rail and 2.5-35mm copper multi- stranded wire.

Each front pole of SPD surge protector must be connected in series with XZSCB series surge backup protector or fuse.

Usually installed in the line of low voltage main distribution cabinet, used for the protection of the secondary power supply equipment, used in the floor of vulnerable to lightning distribution cabinets, elevator, fire control, network equipment, such as in the center of the civil building distribution box, computer, telecom equipment room, elevator, fire control center control room, cable TV room, villa, village resident distribution box, etc.
