2P Photovoltaic DC Voltage Surge Arrester Device Lightning Protection Circuit Breaker 500VDC 20‑40KA

Feature: 1. Maximum Continuous Operating Voltage: Built in short circuit technology for overcurrent, overheat and temperature control. The maximum continuous operating voltage of the voltage surge protection device is 500V. 2. Working Process: When the system surges overvoltage due to lightning or other reasons, the protector immediately opens within nanoseconds, and the surge overvoltage is introduced to the ground to protect the electrical equipment. 3. PC Material: The surge arrester shell is made of PC flame retardant material, which is safer to use. Modular design, use and maintenance is very simple, good electrical conductivity. 4. Electronic Components: Lightning protection circuit breaker uses accurate electronic components for longer service life and more stable performance to help you do your job more efficiently. 5. 35mm Standard Rail Installation: This product uses 2P rail installation, installation is very simple. Standard 35mm rail mounting, and with IP20 protection grade.
