LYD1-PV surge protective device(SPD) is mainly used in photovoltaic low voltage DC distribution system to prevent lighting impulse. The product applied for the full new design, its highest continuous operating voltage up to 1300V, able to effectively prevent the solar battery plates, photovoltaic busbar box, DC distribution cabinet, inverters and other photovoltaic equipment from being damaged by the surge current. U-type structure, limiting pressure type combination. Differential mode common mode protection modeBuilt-in overheating , over-current protection mechanismLocal fault indication, white for normal operation, red after tripping.
