Product Description
385V 10-20KA AC Electric Surge Protector

FSP series surge protector(SPD) is suitable for TN-S, TN-C-S, TT, IT etc. Power supply system of AC50/60Hz, ≤ 380V. The product, using metal oxide varistor, designed to protect both phase and neutral line, is of high electricity resistance under normal operations. In case of surge current or voltage caused by lightning strike or similar, SPD functions quickly to conduct the surge voltage/current to earth and thus effectively prevent the downstream equipments of its protected line from destruction. SPD resumes its high electricity resistance to secure normal operation of the protected power network without presence of the surge voltage. 


1) Temperature control breaker, build-in over currents fuse protector. 
2) ON-OFF indicating window 
3) Plug-in type function unit makes easy replacement 
4) Smallness leak current, response quickly, less residual oltage.
