It has the characteristics of low residual pressure, sensitive reaction, stable performance, reliable work and so on.
With remote signaling contact for control device.
It’s designed according to GB18802.1 IEC61643-11
Fault indication via red mark in the inspection window.
Application:
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.
Installation:
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.
