Surge protection device AC SPD 385V 2 Pole 40K 2D Chip

Product overview

The KY series surge protector (SPD) is suitable for AC 50/60Hz, AC 380V/385V;

TT. TN-S, TN-C, IT, TN-C-S,photovoltaic solar energy and are applied to primary and secondary lightning protection for equipment systems in areas with high lightning risk.

DC Surge Protective Device plays a crucial role in quickly and effectively protecting equipment in the event of overvoltage in DC circuits,preventing equipment damage and ensuring the safe operation of electronic and electrical devices.

●Prevents electric shock caused by electrostatic discharge Protectselectrical equipment from overvoltage damage Preventsfirescausedbystaticelectricityaccumulation.

●Suppresses interference caused by lightning strikes and induced lightning.

SPD conforms to GB/T18802.1/IEC61643-II.

This product complies with IEC60947-2, GB/T140482

Installation Instructions

◆It is installed at the junction of LPZOB or LPZ1 area and LPZ2 area with 35mm standard guide rail, and the connecting steel multi-strand conductor is 2.5 ~ 35mm ².

◆Each pole of SPD must be protected-use fuse or small circuit breaker or special backup protector.

It is suitable for household distribution box, photovoltaic combiner box, computer equipment, information equipment. Electronic equipment and control equipment before or in the nearest socket box.

Main structure and working principle

◆SPD is a port, anti-electric shock protection, indoor fixed installation, voltage limiting type.

◆SPD built-in stripper. When the SPD fails due to overheating and breakdown, the disconnector can automatically disengage from the power grid and give an indication signal at the same time. The visual window shows green when the SPD operates normally, and red when the SPD fails.
