Product Description
Fuse holders are devices used for retaining, protecting, and mounting fuses. Fuse holders come in a range of styles, each designed to suit a specific style of a fuse. Fuse holders can be categorized by their attachment or mounting type. As we mentioned before fuse holders vary, all depending on the fuse it is designed to accommodate and the application and environment it will be used in.
Some of the most common types you will find are:
Base mount- The base of the holder is usually attached to a surface by fixing screws in the centre of the base. Typically used with cartridge fuses.
Inline - Inline fuse holders provide housing for a fuse in a wiring circuit. Cable or wire is attached at each end of the holder, making the in-line connection easy. Often used in vehicle electrical circuits with mini blade fuses.
Panel mount - Specifically designed for mounting directly onto or in an electrical panel. There are two main types of panel mount fuse holders, rectangular snap-in types and cylindrical tube screw-in types. Cap styles can be manual, slotted, or finger grip.
Rail mount - Rail mount holders are specifically designed to be mounted to DIN rails, meaning that they feature a slot for the rail to attach to somewhere in the body of the fuse holder. Rail mount fuse holders can vary according to a few different characteristics, including voltage and current rating, number of poles, terminal type.
Bottle fuse - A holder for cylindrical bottle fuses, usually with a cap to complete the circuit.
PCB Mounts - Holders that are directly fitted to a PCB. PCB mounts come in two basic types, open or fully enclosed. Open PCB mounts include fuse clips, fuse blocks, sockets, and plug-on cap varieties. The fully enclosed variety may use a fuse carrier that is inserted into a holder or may use other means to fully enclose the fuse.

Application
In the field of household appliances: almost all household appliances use fuse holders to prevent electrical appliances from being damaged by overcurrent during use. For example, a fuse holder is installed in the power strip of a television.
Communication equipment field: high frequency and high current often occur in the circuit of communication equipment. If there is no protection of the fuse holder, the circuit is easily damaged. For example, the battery management circuit in a mobile phone needs to use a fuse holder to protect the safety of the circuit.
In the field of automotive electronics: With the continuous improvement of the level of automotive electronics, there are more and more fuse holders in automotive circuits. For example, in the engine control module of a car, a fuse holder is needed to protect the safety of the circuit.
Industrial control field: The stability and reliability of the circuit are very high, so the application of the fuse holder is also very extensive. For example, in a power supply module of an industrial control device, a fuse holder is required to protect the safety of the circuit.
In the field of medical equipment, high-precision and high-stability electronic components are often used in the circuits of medical equipment, so the requirements for fuse holders are also very high. For example, ECG machines, ventilators and other medical equipment need to use the fuse holder to protect the safety of the circuit. The main functions of the fuse holder include protection function and bearing function. The protection function is embodied in that it can prevent the circuit from being overloaded or short-circuited and protect other electronic components in the circuit from being damaged by overcurrent. The bearing function is reflected in its ability to place various fuses in a certain order to facilitate the search and maintenance of subsequent problems. In addition, the fuse holder also has current resistance, voltage resistance, fire rating and other requirements to ensure the safe op
