Video Description
Product Description

1.A range of 10x38mm fuse links specifically designed for protecting photovoltaic strings. These fuse links are capable of interrupting low overcurrents associated with faulted photovoltaic string arrays (reverse current, multi-array fault). 

 

2.DC Fuse mainly used in DC combiner box in solar PV systems. When PV panel or imverter caused overload or short circuit, it trip off immediately, to protect PV panels, DC fuse aslo used to protect other electrical parts in DC circuit, when overload or short circuit.

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

1.Photovoltaic system fuse accord with UL248-1 standard.
2.Photovoltaic battery dc fuse designed to used for photovoltaic (PV) system. 
3.Main effect is to protect the solar panels. Solar panels points in effective condition is broken,.
4.Fault light cells break points at the same time, does not affect other normal work of light from 

the stack.
5.Technical Data  Rated coltage:DC1000V  Breaking capacity:25KA  Function level:PV.
