surge protection device
CN1-B series surge protective devices are used for lightning and overvoltage protectionin AC50/60Hz, 230/400V. The product is with an internal nonserviceable separatingdevice. When the surge protective devices is overcurrent or overvoltageand the puncture is nonsevice able, the nonserviceable separating device will automaticallyseparate from the protector from the electrical network. And simulaneouslythe position display windw will turn red from green.Class One Lightning Protection(Protection Class:B)Class B lightning current SPD protection is used for equal potential connection whenlightning. It is installed between LPZ0 A zone or LPZ0B zone and LPZ1 zone andwidely used for over-voltage protection in all kinds of Class 1 power supply(Class B).
