Part number:Health Geargw14ugds5q Package Dimensions:12 x 10 x 7 cm Features: -Surge Protector: When over voltage surge occurs in the system due to lightning stroke or other reasons, the protector will be quickly opened within nanoseconds, and the surge over voltage will be introduced to the ground to protecting the electrical equipment. -Modular Design: The voltage protector adopts modular design, which is very simple to use and maintain, can be replaced online, and has good conductivity. Low leakage current, faster response time and low residual voltage. -Easy Operation: Accurate electronic components are used, with longer service life and more stable performance, to help you complete the work more effectively. The color of the visual window indicates the working state of the protector. -Simple to Install: Installed by guide rail, which is very simple. Standard 36MM guide rail installation, which can be used together with the circuit breaker of the distribution box. Specification: Item Type: Surge Protective Device Model: NL PV40 Material: PC Maximum Continuous Working Voltage Uc: 1000V DC Nominal Discharge Current In: 20kA, 8/20S. Maximum Discharge Current Imax: 40kA, 8/20S. Voltage Protection Level Up: 3.5kV Pole: 3P Protection Grade: IP20 Working Temperature: -40 - 80 , humidity: 90% under average 25. How to Use: The power must be cut off before installation, and live operation is strictly prohibited. During installation, please connect according to the installation diagram, where + is the positive wire and is the negative wire. Do not connect them incorrectly. After the installation, check whether the working condition is normal.
