The first level surge protector is mainly installed in the main inlet line cabinet of the building, as the first level lightning protection of the building power distribution system, in line with the lightning protection acceptance standards and protection requirements. To meet the GB GB50057-2010 "Building Lightning Protection Design Code Requirements" on T1 test level 1 lightning protection requirements.

25kA 4P:suitable for TN-S and TT power supply system
25kA 3P: suitable for TN-C and IT systems
25kA 2P: Single phase power supply system



The main function of surge protector is to discharge the strong current generated by the transient overvoltage to the ground, and limit the transient overvoltage to the range that the electrical and electronic equipment can withstand the voltage, so that the protected equipment can not be damaged by the impulse voltage. The working principle of surge protector is: surge protector is generally installed at both ends of the protected equipment and grounded. Under normal working conditions, surge protector to the normal power frequency voltage presents high impedance, almost no current through, equivalent to open circuit; When there is a transient overvoltage in the system, the surge protector presents a low impedance to the high-frequency transient overvoltage, which is equivalent to short-circuit the protected equipment, so that the powerful overcurrent generated by the transient overvoltage can be discharged to the ground, and the transient overvoltage is limited to the voltage range that the equipment can withstand, so that the equipment can be protected.
