Product Details
Principle
The working principle of the fuse is a simple relationship between I2R and time. The greater the current, the shorter the fusing or opening time. The power consumption of the fuse is proportional to the square of the current through the fuse. When the power consumption is too high, the fuse blows. This feature also applies to wire harnesses protected by fuses. If the amount of heat generated exceeds the heat of distribution, the temperature of the fuse will increase, when the temperature rises to the fuse fuse melting point fuse occurs when the fuse is to open the circuit to play a protective role.

Structural fratures
Fuse link is made of pure silver(or silver strings),welding low tin and encapsulated in the melt tbe made of high-strength porcelain, the fuse tube filled with high-purity quartz sand chemically processed as the arc medium.Fuse body is connected with contacting terminals by spot welding fuse base suppressed by the resin or plastic casing fitted with contacts and contains the fusion pieces,the connection made by riveting as the support of the appropriate size fuse body parts.This series fuse has a compact and convenient device,use security,beautiful appearance,etc.

Application
This series fuse is suitable for solar pv power generation system, rated voltage 250V to 1500V, rated current 1A to 30A,used in pv power generation equipment as a pv module string and pv array for over current protection,and pv panels and batteries connected in series and parallel,to charge variable flow system for short circuit breaking protection,in pv station and inverter rectifier system for short-circuit breaking protection,as well as pv power eneration system,inrush and short circuit fault voltage for quick break protection,rated breaking capacity to 10-50KA,products confirms to IEC60629.1 and 60629.6.
