Symmetrical Rail 35mm PV Surge Protector 800V For HVAC System

Lightning Surge Protector 20-40KA 800V PV System, Solar Lightning Arrester

OBV5-C40-PV

Prewired modular complete unit for use in photovoltaic systems consisting of a base part and plug-in protection modules

Combined disconnection and short-circuiting device with safe electrical isolation in the protection module prevents fire damage resulting from d.c. switching arcs (patented SCI principle)

Tried and tested fault-resistant Y circuit of the OBV6-C40-PV prevents damage to the surge protective device in case of insulation faults in the generator circuit.

Integrated d.c. fuse allows safe replacement of protection modules without arc formation.

Technology SPD parameter(Note:According to user requirement ,can be customized Uc=140V,440V,550V,voltage range of range of the SPD):

Tip:How can we distinguish the quality of the lightning arrester?

1. It can be seen from the reaction time: determine whether the lightning arrester can respond in time and quickly discharge the lightning current.

2. It can be seen from the insertion loss: this refers to the installation of a lightning protector, the impact of this lightning protector on the line, the smaller the better

3. It can be seen from the number of impact resistance: determines the service life of the lightning arrester. Generally, the gas discharge tube will not drop after being placed for a period of time. If you want to check its quality, you can use an adjustable high-voltage DC power supply to test .

 
Importance of theground connection
Overvoltage protectors (SPD) divert excess energy toground, so limiting the peak voltage to an acceptablevalue for connected electrical equipment.
A ground connection in adequate condition is, therefore,a key aspect for effective protection against overvoltages.Monitoring ground connection condition guaranteesproper operation of surge protection devices.
