Features： 1、Strong Plugging Ability: The photovoltaic fuse has a powerful plugging ability, which is easy to connect and disconnect. Quick installation and removal without any additional instruments. 2、Dustproof and Waterproof: The photovoltaic fuse is well sealed and has a great performance of dustproof. And the waterproof grade of the plug box is IP68. 3、PPO Housing: The shell is made of PPO insulation and flame retardant material, which is heat resistant and anti corrosion, anti oxidation, UV resistance, high and low temperature resistance, and can be used in harsh environments. 4、Circuit Protection: When the fault current of the circuit increases, the circuit will fuse itself to cut off the current, thus protecting the safe operation of the circuit. 5、Copper Tinned Inner Core: The photovoltaic fuse uses copper tinned inner core, which has strong conductivity and is compatible with photovoltaic cables with different insulation diameters.
