Surge Protection Device Circuit Diagram Product overview
XZ- PV40 PV direct vay surge protector is widely used in PV confluence box, PV inverter, PV controller, PV DC cabinet and other equipment. Rated voltage up to 1500V DC, maximum discharge current 40kA, high- energy varistor, nanosecond response speed, effectively prevent the damage caused by lightning overvoltage to photovoltaic power generation system. Products comply with GB 18802.1, GB50057 and IEC61643- 1 standards.
With common mode (MC) and differential mode (MD) protection mode .35mm standard guide rail installation, the zero line with 2.5- -35mm wire connection, grounding wire with more than 6mm double color multi- strand copper wire connection, the length of not more than 500mm.
Usually installed in the DC distribution cabinet, photovoltaic inverter, photovoltaic manifold box.
