FWH-400A is belonging to electrical, specialty fuses. It is designed for automobile circuit protection and used in circuit protection of electrical equipment such as voltage stabilizers, electronic equipment, inverters, and other special electrical appliances. It is a current-limiting type fuse, its main function is to provide the circuit a circuit protection function.

FWH-400A is composed of a ceramic insulator and a strip housing. The ceramic insulator and the strip housing are connected by a metal line, and the strip housing is covered with an insulated housing. The strip housing and ceramic insulator are inserted into a metal shell. At one end of the ceramic insulator is a metal line for connecting the fuse terminal and the device. At one end of the strip housing is a metal line connected to the incoming power line, and at the other end of the strip housing is a metal line connected to the load line.

The working principle of FWH-400A is relatively simple. In the case of normal operation, the fuse link is in the closed (on) position. When the current exceeds the rated current of the fuse, the fuse element will produce heat and generate rapid melting. When the molten metal drops, the two contact points that were originally in electrical connection were separated, which will cut off the power supply and thus protect the circuit.

The fuses of FWH-400A are generally used to protect voltage stabilizers, electronic products, inverters and other special electrical appliances. When the rated current is exceeded, the fuse element breaks automatically to protect the circuit and prevent damage caused by high current. It increases the safety of the electric equipment and ensures the efficient and safe operation of the circuit. It can be used in place of overload protection switch and other circuit protection components in order to achieve the requirements of safe operation of electrical appliances.

FWH-400A has many advantages, such as fast switching speed, small volume, energy saving, explosion protection and convenient installation. All in all, FWH-400A is applicable for automobile circuit protection and electrical equipment safeguarding, and its excellent performance will provide users with efficient and safe circuit protection.
