- Brand NameTowe
- Model NumberAp D20 3P+N
LPZ 2-3 region or higher interfacial area for lightning, fine overvoltage protection of electronic equipment generally used for the third stage (D) Overvoltage
TPS D20 1P+N, TPS D20 2P, TPS D20 3P+N, TPS D20 4P, TPS D20 3P
TPS D20 series of low-voltage distribution system surge protector designed to suppress the surge voltage electrical device designed with a surge protection device is a combination of modular functions, and protect electrical installations and equipment installed in its downstream (eg EDP systems, communication systems, etc.) from damage due to surge switching, electrostatic discharge, induction or direct lightning strike lightning generated, each maximum discharge current of up to 20KA, third-level protection for terminal equipment.
TPS D20 can be used LPZ 2-3 or higher interfacial area lightning region generally fine overvoltage protection for electronic equipment, terminal equipment to prevent over-voltage interference; for the third stage (D) overvoltage protection.
According to IEC 61643-1 and above GB18802.1-2002 selection. Main features:
1 through flow, residual voltage, fast response, no freewheeling
2 Built-in thermal tripping device, so protection from overheating, breakdown failure can automatically disconnect
The modular design
3.Standard 35MM rail mounting, very easy to install and maintain
4 window color display working status, normal green, red, indicating failure of the product
5.optional with remote communication terminals for remote alarm control

TPS D20 for LPZ 2-3 or higher interfacial area lightning region generally fine overvoltage protection for electronic equipment, terminal equipment to prevent over-voltage interference; for the third stage (D) overvoltage protection. By choosing one or two modules may constitute 2P, 3P, 4P, 1P + N, 3P + N and other combinations, to achieve the TT, IT, TN-S, TN-C and TN-C-S power supply system provides surge overvoltage protection.
Usually installed in the front of the power distribution box office or UPS rear output distribution box, power supply phase line (L), neutral (N), respectively, corresponding surge protectors access terminals to ensure secure and reliable, and will surge protectors ground and ground to make a good electrical connection.
Surge protectors should regularly check the work, such as the protection window turns red indicating the deterioration of its front open space, when the fuse is tripped, timely maintenance or replacement module.
Surge protectors equipped with hot-swappable modules for easy maintenance and replacement
