Function: 1. Function This surge protector can protect your AC power system from lightning or surge. 2. Great electrical conductivity: surge protector as internal component, accurate chip, accuracy and strong conductivity is also a nice guarantee. 3. Flame Retardant: Increase the safety of use, reduce the flammability, and can withstand more strength during operation, improve efficiency, allow for a better using experience. 4. Easy Installation: This protector adopts 2P rail mount which is very easy to install. Standard mounting on a 36MM rail and a circuit breaker in a distribution box with the use of. 5. Overvoltage Protection: When a system experiences an overvoltage due to lightning strike or other reasons, the protection immediately opens quickly in nanoseconds and applies an overvoltage to the ground, protecting the power supply with the devices. Specification: Item Type: Surge Protection Device Model: CHLT 40PV Material: PC (fireproof) Maximum continuous working voltage: DC600V Nominal discharge current: 20kA (8/20μs) Maximum discharge current: 40kA (8 / 20μs) Up voltage protection level: ≤2.8kV Number of Poles: 2P Protection level: IP20 Working temperature: -40 ℃ - 80 ℃ Working humidity: ≤90% (average at 25 ℃) Package List: 1 x 2P surge protector 1 x sliding sheet Note: 1. Power supply must be cut off before installation, and work with electricity is strictly prohibited. 2. During installation, connect in accordance with the installation diagram, where + is a positive line, - is a negative line, do not connect incorrectly, after completing the installation, close the automatic circuit breaker (fuse), check if the operating condition is normal.
