CurrentGuard Plus 3 – CGP3 Surge Protective Devices

Powerful CurrentGuard® CGP3 Surge Protective Device (SPD) provides reliable protection for electrical equipment, electronic devices, and appliances against power surges. CGP3 series is available in 60kA-200kA per mode (120kA-400kA per phase) and includes dependable thermally protected MOVs to eliminate overvoltage currents before they damage downstream equipment. The CGP3 SPD is built with multiple advanced monitoring and reporting features such as Tri-Color LED lights, exclusive surge counter display, audible alarm, and dry relays. These innovative features are extremely valuable to provide predictive maintenance options and reduce downtime. CGP3 helps safeguard your customer’s capital investments.
