AC 275V-385V Surge Lightning Arrester Counter 4p 20kA SPD House Surge Protector

⚡ Description :

YRO 2P Solar Power Surge Protection Device 20KA 40KA 275V AC Surge Arrester SPD (in short AC SPD,alias,surge suppressor,surge arrester) is suitable for TN-S, TN-C-S, TT, IT etc, the power supply system of AC 50/60Hz,<380V. When the SPD fails in breakdown for over heat or over-current, the failure release will help electric equipments separate from the power supply system and give the indication signal, it also could be replaced for the module when has operating voltage in Solar PV Systems.
