LY1-50B, LY1-25B switch-type compound power surge protector ( B+C level)

product description
LY1-B series lightning protector is a composite lightning protector designed according to the requirements of SPD Class I classification test . It can be used for the primary and secondary protection of the load equipment of the power line, and prevent the low-voltage equipment from being damaged by overvoltage interference or even direct lightning strike. Application On the interface of lightning protection zone LPZ0A-2. The switch-type composite lightning arrester is designed and manufactured according to IEC61643-1 and GB18802.1 standards. It has a high lightning current discharge capability, and the maximum impact current of a single module can reach 50KA (10/350μs). It can be widely used in the first-level lightning protection protection of equipment system power supply in areas with high lightning strike risk, and can be used in combination for single/three-phase power supply lines .

Features
1: Standard 35mm rail installation, compact structure, double terminals (Kevin method).
2: Equipped with a deterioration status indicator light (the red light is on, the lightning protector is faulty and needs to be replaced in time). Easy to install and maintain.
3: B+C level protection, large discharge energy and low residual pressure. (Iimp50KA Up≤ 2000V per line)
4: Adopt unique self-ignition technology, no power frequency freewheeling, no leakage current, high safety factor.
5: The core components are made of special alloy materials with anti-oxidation, arc ablation resistance and excellent performance, which have strong environmental resistance and long service life.
