The function and structure of automobile fuse holder
This article is substantially about the automobile fuse holder related introduction, and focuses on the machine fuse holder structure, bracket and function for a detailed description.
Auto fuse holder
Machine fuse seat refers to the seat that installs machine fuse, machine fuse seat can be divided into the panel installs machine fuse seat; Lead type machine fuse holder; Auto fuseholder.The panel installs the machine fuse seat to be used for the machine electric appliance, similar as the machine power amplifier, the machine sound box, the machine DVD and so on.

Function and construction of machine fuse holder
In the process of using the machine fuse holder, the fuse can repel the load in a certain range due to the power force or external hindrance caused by the incision current change. When a fairly large load current occurs in the circuit of the machine fuse holder, the fuse should cut off the load current within a fixed time.
Machine fuse seat can cover the safety of other electronic corridor in the circuit to a certain extent. When the circuit has a short circuit and a large current, the fuse can safely cut off the circuit, so as to help them from being damaged by inordinate current.
The rated current in the fuse seat is the valid nominal working current of the fuse. The rated current value is generally 100mA, 160mA, 200mA, 315mA, 400mA, 500mA, 630mA, 800mA, 1A,1.6 a, 2A,2.5 a,3.15 a, 4A, 5A,6.3 a, etc.
The fuse in the machine fuse seat can be used at the voltage equal to or lower than its rated voltage, but generally can not be used in the circuit voltage lesser than the rated voltage of the fuse, the voltage drop in the outfit, the rated current on the fuse.
The thermal balance of machine fuse seat is the voltage measured at both ends and the voltage drop at both ends of the fuse will have a certain effect on the circuit to a certain extent when the temperature is stabilized. Thus, there's no demand for the unequivocal provision of voltage drop in the regulation.
The load current in the auto fuse seat substantially refers to the current flowing through the circuit which is advanced than the normaloperation.However, it may damage other electronic corridor in the circuit, If the load current can not be cut off.
