@PEN OPU4-A40 2P AC Surge Protective Device (SPD) 40kA 275V

Thunderstorms and grid switching create very short, very high voltage spikes that can burn TVs, inverters, routers and other electronics in a second. The @PEN OPU4-A40 is fitted next to the main breaker and connected to earth. When a spike comes, it diverts the extra energy to earth almost instantly.
