Current Guard 3 & Current Guard Plus 3

Current Guard 3 and Current Guard Plus 3 Surge Protection

The powerful Current Guard 3 and Current Guard Plus 3 help protect against utility power anomalies and lightning-induced transient surge events. Their compact and advanced design features thermally protected MOVs to eliminate overvoltage, safeguarding your equipment and capital investments.

Key benefits

Safeguard your capital investments - Help reduce operational downtime and maintenance costs
Absolute protection - CG3 and CGP3 protect sensitive equipment from failure by clamping transient voltage events as close as possible to nominal and redirecting them safely away from connected equipment
Enhanced safety - Thermal protection adds an additional level of protection by taking the SPD offline when reaching a certain temperature
