TRS-A Series SPD
The TRS-A series is a type of graphite gap type SPD (lightning arrester), designed for installation on the main distribution board, used to protect various application places such as residential, office and industrial buildings, and protect electrical equipment from direct or indirect lightning strikes. The series includes three models: TRS-A15, TRS-A25 and TRS-A50, to meet different protection level requirements.

TRS-A15
Suitable for smaller-scale lightning protection needs, designed to protect light-load electrical equipment, especially suitable for homes and small offices.

TRS-A25
Medium capacity surge protection for medium load environments such as offices and small industrial locations.

TRS-A50
The highest level of surge protection model, designed for large industrial facilities to handle strong lightning strikes.
AC/T1+2 SPD
Protect electrical equipment from lightning-induced overvoltage or switch overvoltage, ensuring safe operation of power systems and equipment. Among them, the TRS 30B+C series has passed TUV certification, and the TRS 8 series may be suitable for more complex surge scenarios due to the use of composite technology (MOV+GDT).


TRS30B+C SPD
Widely used in industrial and commercial scenarios, providing dual protection against lightning strikes and switching operation overvoltages.

TRS5 Series SPD
Suitable for power systems requiring high performance surge protection to ensure safe operation of installed equipment.

TRS8 Series SPD
It has both MOV and GDT protection, and is suitable for areas with frequent lightning activities and high-demand electrical systems.
TRS Series SPD
AC/T2 Series TRS Series Type 2 SPDs provide efficient overvoltage protection through Metal Oxide Varistors (MOVs) and are designed as plug-in modules for a variety of applications in main and sub-distribution panels.

TRS Series SPD
Designed for installation environments with limited space, it is suitable for the protection needs of small distribution boxes and distribution boards.

TRS2 Series SPD
Suitable for industrial and commercial scenarios that require high-reliability installation, providing additional protection and operational convenience.

TRS4 Series SPD
The TRS2 model is designed for small spaces, and the TRS4 model has an additional safety lock function to ensure the stability of the module.
TRS-A Series SPD
TRS Series Type 2 Surge Protectors are based on Metal Oxide Varistors (MOVs) and are suitable for installation in sub-panels and main switchboards. They are designed for protection against lightning induced overvoltages and switching overvoltages.

TRS6 Series SPD
Effectively protect the installed equipment from the impact of induced overvoltage or switching operation overvoltage caused by lightning strike.

TRS7 Series SPD
Suitable for industrial and commercial environments that require higher surge carrying capacity to ensure safe operation of equipment.

TRS9 Series SPD
Suitable for installation scenarios that require modular flexibility and protect equipment from lightning strikes and overvoltage.
TRS Series SPD
The TRS series Type 3 surge protector (SPD) adopts a single-piece design and supports DIN rail mounting. It is suitable for a variety of voltage ranges from 24V to 230V and is designed for end-of-line protection of sensitive equipment.

TRSS-30
It is usually installed close to the protected equipment and used in coordination with Type 2 surge protector.

TRSS-60
Usually used for local protection of industrial equipment and precision instruments, installed near the load.

TRSS-255
Widely used in commercial and domestic applications, suitable for installation close to the load position to ensure the safe operation of precision equipment.
