Product Description
Product Overview
LT1 series surge protector （hereinafter referred to as SPD） is suitable for equipment end protection, terminal distribution box and internal information front end, low voltage AC power distribution system IT, TT, TN-C, TN-S, TN-CS, etc. power supply System, surge protection against indirect lightning and direct lightning effects or other transient overvoltages. Class Il surge protector according to IEC61643-1 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
LT1 must 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.
