3P DC 220V Surge Arrester , Class II DC Surge Protection Device For Solar Pv System

Surge protective device, protect against lightning surge voltages in solar system (photovoltaic power supply system).These units must be installed in parallel on the DC networks to be protected and provide common and different modes protection. Its installed location are recommended at both ends of the DC power supply line (solar panel side and inverter/converter side), especially if the line routing is external and long.High energy MOVs equipped with specific thermal disconnectors and related failure indicators.

Performance characteristics:

Adopt the latest thermal separation technology, built-in thermal protection, automatic separation device for short-circuit failure, completely avoid fire;
The core components adopt internationally well-known brands, with excellent performance, stable and reliable work;

Lightning current arrestors OBV10-I-50 meet the type 1 requirement class according to IEC 61643-11. These devices protect low-voltage consumer systems from overvoltages of all types and are available in single-pole to four-pole versions.The voltage-limiting,high-performance spark gaps provide several benefits.A short response time, a low protection level and high current leakage capability with long service life.
