Fitur:
Britec hold patent for the design.
It adopts 35mm standard rail.
Time of response 25ns.
The plug-in module / base design facilitate replacement of a failed module without the need to remove system wiring etc.
There is a failure release mounted on the module of surge protective device.
It consists of a high performance varistor with thermal disconnection tripping device.
When the SPD fails in breakdown for over-heat and over-current, the failure release will help electric device separate from the power system and give the indication signal, green means normal, red means abnormal.
Aplikasi:
Used to guard sensitive equipment from voltage spike.
It is applied to low-voltage distribution system, which is connected in parallel between power supply and system equipment to protect the damage caused by instantaneous overvoltage caused by external (lightning
strike, electromagnetic radiation interference, etc.) or internal (system closing effect, induction and start and stop of capacitive load, etc.).
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.
