Features PC Material The shell of the lightning arrester is made of PC flame retardant material, which is safer to use. Modular design, use and maintenance are very simple, good electrical conductivity. Electronic Components The lightning protection circuit breaker uses precise electronic components for longer life and more stable performance to help you do your job more efficiently. Operation Process: When the system undergoes surge due to lightning or other reasons, the protector opens immediately within a few nanoseconds and the surge is introduced to the ground to protect the electrical equipment. Maximum Continuous Operating Voltage: Built-in short circuit technology for over-current, overheating and temperature control. The maximum continuous operating voltage of the surge protection device is 500 V. 35mm Standard Rail Installation: This product uses 2P rail installation, installation is very simple.
