Specification Of The PCB Mount Commercial Vehicle Fuse Holder JEF-703F 20A 32V

Selection of the Fuse and Holder Solution

The first step is to answer the following questions:
Will the fuse need to accessible for replacement?
How often will the fuse need to be replaced?
Should the end customer of the appliance have access to change the fuse?
Should the fuse only be accessible from outside the appliance?
How much is available to spend on safety and reliability?

1) Requirements and characteristics
The most important standards for fuse-holders, which specify requirements, characteristics and testing methods are:
IEC-publication 257 (1968) and Amendment no. 2 to this publication dated January 1989.
UL-standard no. 512.

2) Rerating (Derating) a Fuseholder

Selection Considerations for Fuseholders and Fuse Blocks

Equally important to the selection of the proper fuse is the correct selection of the proper fuseholder or fuse block for a given application. Fuseholders are available using most of the same Selection Considerations outlined for UL fuse classes.

Considerations for fuseholders include:
Current Rating
Voltage Rating
Interrupting Rating
Physical Size
Indication

Additional selection considerations for fuseholders and fuseblocks include:

1) Number of poles
2) Mounting configuration
3) Connector type
4) Number of Poles

5) Mounting Configuration
6) Connector Type Screw/Screw with pressure plated/Box Lug

Function Of The Fuse Holder

The fuse holder mainly refers to the seat installed in the fuse, which can be divided into lead fuse holder, panel fuse holder, automobile fuse holder, etc. Commonly used in power amplifiers, speakers, massage chairs and other electrical equipment; fuse clips are often used in small electrical appliances, mainly used for the connection or wiring harness of industrial machinery; automobile fuse holders can be divided into wire-type automobile fuse holders and panel-type automobile fuse holders. The uses are very different. Any kind of fuse clip is very resistant to current and voltage, and in the case of a relatively high fire rating, it generally needs to pass relevant certification.

The improvement of the fuse holder structure mainly refers to the display of the fusion status, no need to replace, and self-replication of the fuse holder. First, many communicating holes are integrated with the first guide, and each hole is connected by screws, or many communicating with each other. Each wire is directly connected to the first wire through an electrical connection, and between the second wires is a self-replicating fuse. In fact, it means the same, knowledge makes appropriate changes to the structure. This ensures the use of fuses.
