Fitur:
Visual status display
Labeled connections
Type 2 (class II/C) for main boards, distribution boards and consumer units.
Available with and without remote signalling contacts.
1 pole up to 4 poles protected.
BR-80 consists of a high performance varistor block with thermal disconnection device. The plug-in module/base design facilitates replacement of a failed module in situ without the need to remove system wiring.
Solutions to meet IEC 61643-1 and EN 61643-11
Aplikasi:
Distribution switch board located downstream from a Type 1 Lightning Current Arrester.
Protecting them from direct and indirect lightning impulse and other transient overvoltage.
Protects low-voltage systems against overvoltage triggered by lightning strikes or grid switching operations.
Ideal for industrial applications.
At the origin of the electrical installation in the main switchboard, in areas where electromagnetic fields caused by lightning currents are dominant (excluding a direct strike).
Suitable for TN-C systems.
Preventing the spread of medium overvoltage (Up) in the electrical installation and protecting equipment that is connected to it.
