Developed and patented by Cable Innovations, the CLPS-3009 combines the latest surge suppression technology (Sidactor® ) with Cable Innovations patented design to create the toughest surge suppressor ever built. The CLPS-3009 protects those areas that the CLPS-3009PI (power inserter) is unable to protect due to distance or system configuration, including feeder lines and power stop points on trunk lines. CLPS-3009 Surge Suppressor Solid state Sidactor surge protection, for reliability and durability   Over voltages taken off center conductor (patented) Superior Grounding - Surge testing ANSI C-62.41 (IEEE 587) 100% Voltage testing Protect Where ever cable line surge suppression is needed, especially at the end of powering.
