Fitur:
Type 1+2.
High discharge capacity in a certain small size.
High follow current extinction and limitation due to no follow current technology.
Reliable safety due to double integrated disconnections with double protections.
Failure indication window, remote alarm terminal optional.
Plug design, easy maintenance.
High security performance.
Green light in notice window indicates normal; red indicates broken, replacement notice, which is clear and easy distinguished.
Indoor fixed installation, voltage limited type.
Small volume, pluggable.
Aplikasi:
To prevent power supply equipment from being damaged by surge and lightning.
Use on buildings in applications where there is an external lightning protection system installed, usually installed at the service entrance.
Widely used in the transformer low-voltage side as the first protection of the power supply.
Instalasi:
Installed in low-voltage distributions at the boundary of LPZ 0–LPZ 1 zones and higher to prevent overvoltage effects induced during a lightning strike and to prevent switching overvoltage.
Install in the main distribution cabinet/box of the low-voltage cabinet and the incoming line cabinet.
Recommended for main distribution boards.
During installation, please connect according to the installation schematic diagram, where L1, L2 and L3 are phase lines, N is the zero line and PE is the ground line.
Grounding should conform to the requirements of the specification of lightning protection.
