Class I+II / Type 1+2 Surge Protection For Power transfer equipment
*DC surge protector is an electrical component used to limit transient over-voltage phenomenon. Because it needs to operate for a long time, there will be aging. If the DC surge protector is used for a long time, the aging caused by it will not be timely. If the facility is updated, it may cause performance degradation, failure and other malfunctions. Therefore, the DC surge protector needs to be inspected regularly. If the inspection result shows aging or the status indicator is invalid, please replace the DC surge protector in time.
OBV5-I-25
Class I+II surge arrester, OBV10-I-25 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.

What skills should lightning protectors have in the selection?
1.Confirm power supply system
First of all, you must determine what your power distribution system is like, whether it is TT, TN or IT system. After determining the power distribution system, you can choose the protection mode and wiring method of the lightning arrester to select the appropriate lightning arrester.
For example, TN-C uses 3P lightning protection device, TN-S uses 4P, TT uses 3P+N, etc.
2.Know the main parameters of the lightning arrester.
