High reputation Spd Electrical Device - Surge Protector Device 18OBO Structure – Leihao Detail:
TN-C-S system
Surge in power supply system mainly comes from two reasons: external (lightning) and internal (start-up, stop and failure of electrical equipment, etc.). Surge is often characterized by short time (overvoltage caused by lightning is often in microsecond level and overvoltage caused by electrical equipment is often in millisecond level), but instantaneous voltage and current are extremely large, which is likely to cause harm to electrical equipment and cables, so surge protectors are needed to protect them. Surge ProtecTIve Device (SPD) is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines, and is mainly used to limit overvoltage and discharge surge current. Surge protectors are generally connected in parallel with protected equipment, which can shunt and limit voltage when overvoltage occurs. Prevent excessive current and voltage from damaging equipment.
Structure and principle
LHSPD is a port ,shocking protection, indoor –mounted installation, voltage-limited.
LHSPD hold disconnector inside, then LHSPD breakdown failure by over heating,the disconnector can remove from the power grid automatically, and show indication signal, when LHSPD is working properly, visible window display green , lt display red when it breakdown and disconnect. 1P+N ,2P+N ,3P+N spd consist of 1P ,2P ,3P SPD + NPE zero protection module , apply to TN-S、 TN-C-S and other power supply system
Product installation
With 35mm standard DIN-rail mounting, connecting copper stranded conductor is 2.5~35 mm².
At front of LHSPD each pole must be setted protection —used fuse or miniature circuit breaker lightning current LHSPD protection ,after LHSPD breakdown to short circuit protection.
LHSPD install on protected line (equipment) to the front and connected to supply line. A class products install in the building home-entry line hold large surge current total distribution box.B,C class products most install on the floor distribution box ,D class products close to the front – end equipment that smaller surge current, smaller residual voltage place
