Fitur:
The BR-25VG 1P is an Type 1+2+3 AC surge protector device designed to protect at the entrance of the electrical installation.
Powerful components, suitable for all kinds of common power systems.
There is a thermal cutoff member inside the protective device, when the device is over-current or over-voltage, the thermal cutoff member will automatically separate from the surge protective device from the electrical network, and the indication window will turn red from green.
The unit is designed to be used between Zone O and Zone 1 (according to IEC62305-4 definition of Lightning Protection Area).
This SPD is particularly useful in a high lightning density area where the risk of heavy surge current or even direct strike is high (e.g.: buildings equipped with lightning rods).
According to EN 61643-11 & IEC 61643-11
The BR-25VG 1P is one-pole SPD.
Aplikasi:
• Used in AC power line of house, bank, telecom tower and so on.
• Ini berlaku untuk proteksi petir untuk sistem tenaga listrik di area dengan risiko petir tinggi (LPZ0B atau antarmuka antara LPZ0B dan LPZ1).
• Suitable as the first step of protection in incoming power supply panels and areas with greater exposure to the atmosphere, where installations are usually provided with an external lightning protection system.
Instalasi:
• Power must be cut off before installation. Live operation is prohibited.
• It is recommended that a fuse or circuit breaker be connected in series at the front end of the surge protection.
• SPD is installed in parallel at the power supply inlet end of the building distribution box or the equipment room. The product is installed in the guide rail type. If conditions permit, the Kevin connection mode can be adopted.
• During installation, connect the device according to the installation diagram, where L is the phase line,N is the neutral line, and PE is the ground line. Do not misconnect the device. After the installation is complete, turn on the automatic circuit breaker and check whether the working status is normal.
• When the SPD is in use, check the status of the fault display window regularly. If the fault display window is red or the remote terminal outputs an alarm signal, it indicates that the SPD is faulty and should be repaired or replaced in time.
• Suitable for indoor operation, such as installed in the outdoor, must be equipped with waterproof shell.
