3P 20-40kA 275V AC SPD

YRO 3P 20-40kA 275V AC SPD are built according to the IEC 61643-11 standard, which lays a solid foundation for their superior performance, enabling accurate and efficient protection against surge overvoltages. The shell is made of PE material, which has excellent comprehensive properties and can withstand erosion under different environmental conditions. The insulation treatment method of PVC hot dip molding makes the insulation performance of the product reach a high level, and can effectively prevent current leakage. In addition, having a CE certificate means that the product has passed strict quality testing and certification. The arrester can cope with the surge current impact of 20-40kA, providing comprehensive and reliable lightning protection for the three phase AC system.

Professional standards: Designed according to IEC 61643-11 standards, the lightning protection capability is professional and reliable, which meets the needs of the communication system.
Durable shell: PE material shell, strong resistance to environmental erosion, to ensure the safety of internal components.
High efficiency insulation: PVC hot dip molding insulation, strengthen electrical safety, avoid the risk of leakage.
International certification: Holding CE certificate, excellent product quality, can be used in a variety of scenarios.

From the internal structure, the layout of the three phase surge protection line is scientific and reasonable, and the phases cooperate with each other without interfering with each other, which can cope with the surge current in a balanced way. The surface treatment process of PE shell is delicate, not only the appearance is clean, but also further improve its dirt resistance, wear resistance and other properties, so that it can always maintain a good appearance and protective function in the long term use process. The insulation structure of PVC hot dip molding plays a key role in the key positions, such as the wiring parts of the product, ensuring the reliability of the electrical insulation at the connection, preventing electrical failures caused by weak insulation, and comprehensively guaranteeing the safe and stable operation of the AC power system.
