The key point in the application of the car fuse holder is the holder of the device in the car fuse, and its products can be effectively divided into the control panel device car fuse holder, the wire type car fuse holder, and the car fuse clip. Control panel equipment Car fuse holders are mostly used in car household appliances, such as car power amplifiers, car stereos, car DVDs, etc.

In the course of the development and use of the car fuse holder, its fuse can accept the load that must be planned as a whole when the current fluctuates due to its switching power supply or external troubles, and the circuit in the car fuse holder shows a very large When the load current is applied, the fuse shall disconnect the load current within a fixed time.

The car fuse holder can maintain the safety of other electronic components in the circuit to a certain level. When a short-circuit fault occurs in the circuit and shows its large current, the fuse can reliably disconnect the circuit, which will cause So that they can be protected from damage caused by overcurrent.

The fuse in the car fuse holder can be used at a working voltage equal to or lower than its rated current, but generally it cannot be used in a circuit where the circuit working voltage exceeds the rated current of the fuse, and the current in the machinery and equipment is correct. The fuse is carrying rated current.

The thermal cycle of the fuse holder, that is, when the temperature tends to be stable, the working voltage on both sides and the voltage on both sides of the fuse will have certain harm to the circuit at a certain level, so the current is clearly stipulated in the regulations. There are no requirements in the rules. The load current in the car fuse holder mainly refers to the current passing through the circuit that exceeds all normal operation. If the load current cannot be disconnected, it may cause damage to other electronic components in the circuit. .
