Feature:1. Lightning Surge Protector: When there is a surge overvoltage in the circuit, the protector opens quickly and introduces the surge overvoltage into the ground to ensure the safety of electrical equipment.2. Accuracy Components: The accuracy electronic components inside the surge protector make it more stable and work more efficiently.3. PC Flame Retardant Shell: The protector shell is made of PC insulating flame retardant material, which is waterproof, making it safer to use.4. Easy to Maintain: The surge protector is modular in design, very easy to use and maintain, and has good electrical conductivity.5. Rail Installation: The protector adopts 3P rail installation, the installation is very simple, and it can be used with the circuit breaker of the distribution box.Specification:Item Type: Lightning Surge ProtectorMaterial: PC flame retardantModel: CHLT-40PVMaximum Continuous Working Voltage Uc: 600V DCNominal Discharge Current In: 20kA (8/20s)Maximum Discharge Current Imax: 40kA (8/20s)Voltage Protection Level Up: 2.8kVNumber of Poles: 3PProtection Class: IP20Working Temperature: -40~80Humidity: 90% (average 25).Package List:1 x Lightning Surge Protector2 x SliderNote:1. The power supply must be cut off before installation, and live operation is strictly prohibited2. Please connect as shown in the installation diagram during installation, in which + is the positive wire and ‑ is the negative wire. Do not make wrong connections. After the installation is complete, close the automatic circuit breaker (fuse) switch to check whether the working state is normal.
