Electronic Component Protection Plug-in Fast Blow Ceramic High Voltage DC Fuse

Product Description

Electronic Component Protection Plug-in Fast Blow Ceramic High Voltage DC Fuse
 

Product Introduction

Jinghui Ceramic specializes in the production of ceramic tubes for fuses, which come in both square and round shapes. A fuse is an electrical component installed in a circuit to ensure its safe operation. When the current abnormally rises to a certain height and at a certain time, the fuse will automatically cut off the current, thereby protecting the safe operation of the circuit.

Ceramic fuses are fuses made of ceramic materials. The fuse wire is generally copper or copper alloy, and it is connected to the two ports of the fuse by welding. The advantages of ceramic fuses are high breaking capacity and good load characteristics, as well as low resistance and thermal inertia. Therefore, ceramic fuses can play a better role in special environments such as high voltage and high frequency.


The selection of fuses needs to consider the use environment. For example, a distribution device with a rated current of 100A generally uses a cartridge fuse; a screw fuse is generally used for motor protection; a plug-in fuse is generally used for lighting circuits and small motors; and a quick fuse should be selected to protect semiconductor components.

 

Product Applications

Time Delay vs Fast Acting Fuse

Fast Acting Fuse: mostly used in circuit boards, it will melt instantly as long as the current exceeds its rated value. Mainly used for short-circuit protection of semiconductor rectifier components or rectifier devices.

Time Delay Fuse: The current of some circuits at the moment of switching is several times greater than the normal working current. Although the peak current is very high, it appears for a very short time. Fast acting fuses cannot withstand this impact current, but time delay fuses can. Its fuse is specially processed and has the function of absorbing energy. Adjusting the amount of energy absorption can make it both withstand the impact current and provide protection against overload. Mainly used to protect wires and cables.


Ceramic Fuse vs Glass Fuse

		Ceramic Fuse	Glass Fuse
1	Different shell materials	Uses ceramic as fuse body.	Use glass as fuse body.
2	Different functions	1. Better explosion-proof performance. 2. Not as easy to break as glass fuse. 3. Larger overcurrent.	1. Poor explosion-proof performance. 2. Easy to break. 3. Smaller overcurrent.
3	Different heat dissipation effect	Good heat dissipation.	Poor heat dissipation.
4	Different application ranges	More used in circuits with larger currents.	Usually used in circuits with smaller currents.
