Surge Protective Device 20‑40KA 3P 1000V Photovoltaic PV Voltage Protection Arrester Protector

Feature: 1. 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. 2. High in Safety: The casing of the surge protective device is made of PC flame retardant material, which is safer to use. Built in over current, overheating and temperature controlled short circuit design. 3. 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. 4. 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. 5. 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.
