4P Surge Protector 40KA Surge Arrester SPD Application:
• Protecting low voltage equipment from surge damages.
• Used to protect electrical systems and load electrical equipment
from lightning and instantaneous overvoltage
• Applied in modular SPD Class II (Class C) for TNS power supply
system.
4P Surge Protector 40KA Surge Arrester SPD Advantage:
• High discharge current.
• Voltage protection level (Up) is low
• Interchangeable modules varistors
• IP20 protection
• Incorporate technology-based high energy varistors
4P Surge Protector 40KA Surge Arrester SPD Installation:
• The type 2 arresters must install into sub-distribution boards
after main distribution boards containing type 1 arresters.
• For proper operation between type 1 and type 2 arresters at least
10- 15 m cable or wire must be otherwise a decoupling coil have to
install between the two devices.
• In areas where storms are frequent, it is strongly recommended to
install additional protection systems.
