The normal working current of the circuit is 6A. If the fuse is also 6A, the fuse will blow. If your fuse is 10A, it is no problem to connect to the normal working circuit, but if there is any fault in the circuit (such as a short circuit), the current will exceed 6A. If it reaches 10A The fuse will ... Read More

1. A DC circuit (direct current circuit, dc circuit) is a circuit in which the direction of the current does not change, and the magnitude of the current in the DC circuit can be changed. The magnitude and direction of the current are constant is called constant current. 2. DC current will only flow ... Read More

The reason why the resistance of the fuse is large is as follows: When the material and shape of the fuse are determined, its resistance R is relatively determined (if its resistance temperature coefficient is not considered). When current flows through it, it heats up, which increases over time. ... Read More

The 240V fuse is designed for equipment using 220V voltage, and the 500V fuse is designed for equipment using 380V voltage. 500V/50A fuses can be used on equipment using 220V voltage, there is no problem at all, because the fuse current is the same, both are 50A, 500V is better than 240V arc ...

Regardless of high voltage or low voltage, the fuse of the power system is selected according to the capacity and rated current of the transformer. If the capacity of a single transformer is 100KVA or below, the high-voltage side is selected according to 2 to 3 times the rated current of the ... Read More

Since the fuse has a certain fusing delay characteristic, why sometimes the system is normal, but the fuse blows instead? There are three reasons: 1) The most common reason is that the type selection is unreasonable, and the rated current of the system is close to the rated current of the fuse, or ... Read More

The fuse generates heat due to the flow of current, and blows when it reaches a certain value. In order not to affect the normal operation of the system, the fuse 120S cannot be blown under 2.1 times the rated current; in order to effectively protect the system, the greater the overcurrent, the ...

The meaning of the insurance resistor is to divide the voltage and limit the current. It is generally connected in series with the load (electrical appliance) to prevent the load (electrical appliance) from burning out and forming a short circuit. It is also the role of insurance. I don’t know what ... Read More
