Product introduction
Level D series surge protection devices are suitable for single phase power supply system of exchange 50/60Hz, which are used to equipotential connection between LPZ2 and LPZ3 area interface for protecting power grid in case lightning stroke and surge overvoltage.
The protection level of surge protection device is D,user must use and install after installing preceding stage surge protection device ,or else it will be damaged by overcurrent
Features:
Level D overvoltage protector
Rating discharge current is big with fast response.
Adopt modular design and easy for installation and maintenance
Own overvoltage ,overcurrent and voltage limiting functions

Product application Range
Level D SPD is used for lightning stroke equipotential connection and install on the junction between LPZOB and LPZ2
It is usually installed at floor distribution box, computer center, telecom center, elevator control room, cable TV, building automation room, security monitoring center ,firefighting center, industry control room, frequency conversion equipment room ,hospital operation room, CICU and distribution box with electronic medical equipment .
Instructions
It is usually installed in front of computer equipment, information equipment and control equipment or Level D surge protection device with 220V socket device.
The protector adopt standard 35mm orbit installation and 2.5-3.5mm2 cooper wire connection, whose length can’t pass 500mm. The ground wire used 4.0-4.5mm2 Bi-Color cable to make use of random connector lug for connection
