In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current. It is a sacrificial device; once a fuse has operated it is an open circuit, and must be replaced or rewired, depending on its type.

Fuses have been used as essential safety devices from the early days of electrical engineering. Today there are thousands of different fuse designs which have specific current and voltage ratings, breaking capacity, and response times, depending on the application. The time and current operating characteristics of fuses are chosen to provide adequate protection without needless interruption. Wiring regulations usually define a maximum fuse current rating for particular circuits. Short circuits, overloading, mismatched loads, or device failure are the prime or some of the reasons for fuse operation. When a damaged live wire makes contact with a metal case that is connected to ground, a short circuit will form and the fuse will blow.

Selection of the Fuse and Holder Solution

The first step is to answer the following questions:

• Will the fuse need to accessible for replacement?
• How often will the fuse need to be replaced?
• Should the end customer of the appliance have access to change the fuse?
• Should the fuse only be accessible from outside the appliance?
• How much is available to spend on safety and reliability?

5.1.2. Requirements and characteristics

The most important standards for fuse-holders, which specify requirements, characteristics and testing methods are:

• IEC-publication 257 (1968) and Amendment no. 2 to this publication dated January 1989.
• UL-standard no. 512.

• Founded in 1999, we have been focused on manufacturing over-current, over-temperature and other circuit protection components.
• Our main products include fuses, fuse holders, thermal switches, circuit breakers and temperature sensors, which are widely used in various kinds of electronic devices, such as consumer electronics, mobile terminals, household appliances, lighting appliances, power supplies, adapters, automobile and marine applications. We have acquired ISO9001/UL/cUL/VDE/CCC/CQC safety certificates.
• After serving our valuable clients in China market over 20 years, we have become one of the leading suppliers of circuit protection components.
