25kA Class I+II+III Surge Protector Feature:
• Part name: Class I+II+III surge protector
• 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.
• Model number: BR-25M 1P
• According to EN 61643-11 & IEC 61643-1
• Maximum continuous operating voltage Uc: 150VAC/275VAC/320VAC

25kA Class I+II+III Surge Protector Application:
• It is mainly used for the Class I lightning protection of AC distribution system
• 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.
• Used to protect electrical and electronic equipment from induced voltages, operating transients voltage, and overvoltages.
Single Phase SPD Connection Diagram: In an electrical systems, surge protection devices (SPDs) are usually installed in tap-off configuration (in parallel) between the live conductors and the earth.
SPD (Sistema de Protección contra Sobretensiones) es un equipo que protege los aparatos de las sobretensiones.
When an SPD senses a transient overvoltage (also known as a voltage spike or a power surge) in a circuit, it operates by ‘diverting’ the current from the circuit to and through the connected surge protector, rather like a bypass route for current.
