General

• YCS6 C series Surge Protection Device is suitable for TT, IT, TN-S, TN-C and TN-C-S, the power supply system with the rated voltage up to 230/400V and AC 50/60Hz.
• It can work as the equipotential bonding when the lightning strike. Its design corresponds to IEC61643 1, GB18802.1 and GB50057. ​ ​The product is mainly applied to protect the low voltage electric equipment and Prevent the surge causing by the thunder Or switching overvoltage.
• As a univoltage limiting device, YCS6-B is equipped with the heavy-duty Zinc Oxide piezoresistor. YCS6 C series (Protection level: II) Protection Device need to be installed on the up link of the equipment, connecting with outer conductor(L) or neutral conductor(N) and the earthing device.
• Users can install the YCS6 C in the boundary of LPZOA or LPZ1, usually in the incoming line low voltage main distribution box.
