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 Protector Material: PC flame retardant Model: CHLT-40PV Maximum Continuous Working Voltage Uc: 600V DC Nominal Discharge Current In: 20kA (8/20μs) Maximum Discharge Current Imax: 40kA (8/20μs) Voltage Protection Level Up: ≤2.8kV Number of Poles: 3P Protection Class: IP20 Working Temperature: -40℃~80℃ Humidity: ≤90% (average 25℃). Package List: 1 x Lightning Surge Protector2 x Slider Note: 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.
