Class Il surge protector according to EC61643-1 standard.
SPD has common mode（MC） and differential mode（MD） protection methods.
SPD conforms to GB/T18802.1/IEC61643-4.
Product Installation
Install at the junction of the LPZl or LPZ2 area and the LPZ3 area, using a standard rail of 35 mm, connecting a copper multi-strand wire of 2.5-16 mm2
CHLTmust be protected at each pole-using a fuse or small circuit breaker.
Suitable for household distribution box, computer equipment, information equipment, electronic equipment and control equipment in front of or near the socket box.
Main structure
SPD is a-port, anti-electric shock protection, indoor fixed installation, voltage limit type.
The SPD has a built-in detach. When the SPD fails due to overheating and breakdown, the detach can automatically detach it from the grid and give an indication signal.
When the SPD is working normally, the visual window appears green, and the red is displayed after the failure is separated.
