Drop out fuses and load-drop fuses are outdoor high voltage protection appliances. It is installed on the high voltage side of the distribution transformer or on the branch line of the distribution line. used as a short circuit of the transformer and the line, overload protection and split load current.
The drop fuse is composed of two parts:
An insulating bracket and a fuse tube. The static contact is installed at two ends of the insulating bracket, the movable contact is installed at both ends of the fuse tube, and the fuse tube is composed of an inner arc extinguishing tube and an outer layer.
It consists of a phenolic paper tube or an epoxy glass tube. The load drop fuse enhances the elastic auxiliary contact and the arc extinguishing cover to divide and combine the load current.
Product use environment:
1. The ambient temperature is not higher than +40 C, not lower than-40 C
2.The altitude does not exceed 3000m
3.The maximum wind speed does not exceed 35m/s

Features:
Higher voltage rating provides overall system efficiency using smaller, more economical
conductors while meeting the needs of higher voltage battery packs.
Higher interrupting rating protects high capacity battery packs needed for vehicle acceleration and range requirements.
Up to ten times faster opening under high fault current conditions helps assure reliable
protection of circuits and components.
Requires up to 48% less space than conventional high speed fuses to help reduce
space and weight.
Data logging system marks each fuse with a serial number and date code for traceability of Critical to Quality characteristics.
To help project the life of the fuse in your application, unique driving profiles and
conditions can be simulated to verify proper fuse size and performance under a wide range of driving behaviors.
Operation as low as 200% overload provides back up protection to the battery management system.
Can be applied in parallel to realize greater ampacity within sizing guidelines.
We can supply glass, ceramic, auto, slow-acting cartridge, and temperature limit fuses, fuse clips, fuse holders and blocks, fuse links, as well as other electronic products.
Our factory speclized in fuse and fuse holder for 40years in china.
In electronics and electrical engineering, a fuse (from the french fusée, italian fuso, "spindle" is a type of low resistance resistor that acts as a sacrificial device to provide overcurrent protection, of either the load or source circuit. Its essential component is a metal wire or strip that melts when too much current flows, which interrupts the circuit in which it is connected. Short circuit, overloading, mismatched loads or device failure are the prime reasons for excessive current.
*fuse supporter (fuse base)
In many application cases, fuse links are installe on fuse supporters/application
Cases.They are not to be used as switches for connectionand disconnecton of the load.
*factors to be considered for selection of fuse links
1.Normal working current
2.Working voltage
3.Ambient temperture
4.Overload current and cutout time
5.Possible malfunction current
6.Impluse current surge current starting current and transient value of the line
7.Size and dimensions connection methods indicators etc
