XZ1-SPD10、20 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. It can jump into the power line， signal transmission line instantaneous overvoltage limit in the equipment or system can withstand the voltage range, or strong lightning current discharge into the ground, so as to protect the protected equipment or system from impact and damage. As a single voltage limiting device. Products in line with GB18802. 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 LPZ1/LPZ2 and LPZ3 with 35mm standard guide rail and 2.5- 35 mm copper multi- strand wire.

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

It is usually installed at the inlet low- voltage main distribution cabinet for the protection of third and fourth level power supply equipment. It is often used in power distribution equipment such as terminal box, large equipment control box, front- end cabinet UPS of important equipment, camera and so on, which are vulnerable to lightning. In the industrial and civilian construction of distribution box, computer center, telecommunications room, elevator control room, cable' TV room, fire center, villas, residential distribution box, etc.
