NL2-C40 4P Surge Protection Device

NL2-C40 4P Surge Protection DeviceNL2-C40 4P Surge Protection Device

Module design, convenient installation, with easy electric maintains operation
Built-in over current and over heat, temperature control open circuit technology
Adopt independent intelligence property right and high performance sensitivity resistance plates
Small creepage current, fast response time, remnant low voltage
Indicate alarm display, green(normal), red(malfunction)
A sensitive heat tripping/deterioration device is placed inside the protection module, when the protection device gets damaged because of overload, the inbuilt tripper shall act in time to cut off the connection with the power supply

SPD Type 2 according to EN 61643-11

SPD Class II according to IEC 61643-1

Classification C according to E DIN VDE 0675-6
