Fitur:
The BR-25M 1P is an Type 1+2+3 AC surge protector device designed to protect at the entrance of the electrical installation.
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.
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 61643-1
The BR-25M 1P is one-pole SPD.
Up: ≤1.3kV.
Standardized 35mm Din rail mounting, compact bistable rail fixed buckle, easy to disassemble.
Screw terminal connection, tightening force equivalent to twice the standard, make the connection more reliable and safer.
Aplikasi:
Used in AC power line of house, bank, telecom tower and so on.
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:
The 25kA first level surge protector shall be installed in a waterproof environment and free from violent vibration.
Ensure that the maximum continuous working voltage of the surge protector meets the actual requirements.
The wire connecting the surge protector should be as short and straight as possible, and the total length of the wire should be controlled within 0.5 meters.
Before powering on the power supply, check whether the cable is securely connected to the wiring terminal and whether the ground is reliable.
