Fuses

0324020.H Application Field and Working Principle

A fuse is a type of protective device made to disconnect a circuit in case unintentional over-current flows through it. Fuse widely used in many industry and household electric appliances, like microwave oven, air conditioner, television set and computer are all protected by fuses. The 0324020.H fuse is specially designed for multiple uses in a variety of application fields and is used in circuit protection and over-current protection.The 03240 20.H fuse features a highly efficient construction with dual functions of time-delay and over-current protection. It consists of two parts, the base and the element. The base is made of copper and the element is made of phosphor bronze plated with silver. The element is designed with a spiral made of thin metal wires that have a very low resistance. When current flows through the fuse, the element expands from both ends and begins to roll up as the current increases. When the current reaches its maximum, the element disengages the contacts of the base, thereby disconnecting the current flow.The 0324020.H fuse can be easily installed, and the time-delay feature allows the fuse to respond to sudden current spikes which can cause malfunction. It also prevents over-current events from causing irreparable damage to the electric appliance. To ensure the correct installation of the fuse, the manufacturer has specified that the base should be securely fixed to the appliance. When the fuse is being used with a 220-Volt circuit, it should be installed in a dry environment and on a surface that is clean and flat.In addition to circuit protection, the 0324020.H fuse also has several other uses. It can be used as a circuit breaker, to interrupt an overload situation. It can also be used as a switch contact in order to open and close a circuit. Fuses also have tremendous utility in electrical generated power applications, as they can be used to provide surge protection. This ensures that the components within the system remain safe in the event of power surges.To sum up, the 0324020.H fuse has many advantages. Not only does it provide efficient circuit protection, but it also can be used as a switch contact, circuit breaker and surge protector. Moreover, it is relatively easy to install and features a time-delay characteristic that can protect expensive electronics from over-current events.
