Surge protector (surge protector) (referred to as SPD), suitable for AC 50/60HZ, rated voltage 220V to 380V power supply system (or communication system), for indirect lightning and direct lightning effects or other transient overvoltage Surge protection is suitable for the requirements of surge protection in family residences, tertiary industries and industrial fields.
The surge protector, like other electrical appliances, has its own parameters. The applicable current is AC, and the AC size is 50/60HZ, and the required rated voltage is 230V~380V; if the voltage is instantaneously too high or too low, it can be used for Electrical appliances are protected, and it has a protective effect on surges under the influence of lightning. It is needed for household appliances, shopping malls, buildings and other industrial fields. It has combined protection modes such as phase-to-phase, phase-to-ground and neutral-to-ground.
CHXI-G-40PVdirectvaysurge protector is widely used in PV confluence box， PV inverter， PV controller， PVDC cabinet and other equipment.Rated voltage upto1500VDC， 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, GB50057andIEC 61643-1 standards.
With common mode(MC) and differential mode(MD) protection mode.35mm standard guiderail installation， the zero line with 2.5-35mmwire 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.
