TRS6 Surge Protection Device
TRS6 series surge protection device (hereinafter referred to as TVSS) are suitable for AC 50/60HZ, rated voltage
up to 380v LT、TT、TN-C、TN-S、TN-C-S and other power supply system, it protect to indirect and direct lighting
effect or other transient over voltage.
TVSS design according with GB18802.1/IEC61643-1 standard.
Structure and principle
TVSS is a port ,shocking protection, indoor –mounted installation, voltage-limited.
TVSS hold disconnector inside, then TVSS breakdown failure by over heating,the disconnector can remove form the
power grid automatically, and show indication signal, when TVSS is working properly, visible window display green , lt
display red when it breakdown and disconnect.
1P+N ,2P+N ,3P+N spd consist of 1P ,2P ,3P TVSS + NPE zero protection module , apply to TN-S、 TN-C-S and
other power supply system
With 35mm standard DIN-rail mounting, connecting copper stranded conductor is 2.5~35 mm².
At front of TVSS each pole must be setted protection ---used fuse or miniature circuit breaker lightning current TVSS
protection ,after TVSS breakdown to short circuit protection.
TVSS install on protected line (equipment) to the front and c onnected to supply line. A class products install in the
building home-entry line hold large surge current total distribution box.B,C class products most install on the floor distribution
box ,D class products close to the front – end equipment that smaller surge current, smaller residual voltage place
