Fuse Holders
Fuse holders are devices used for retaining, protecting, and mounting fuses. They come in a range of styles, each designed to suit a specific type of fuse. Fuse holders can be categorised by their attachment or fuse mounting type, including panel mount, PCB mount, and DIN rail mount. Additionally, fuse carriers and fuse housing are essential components that ensure the secure placement and easy replacement of fuses. RS offers an extensive range of high-quality devices for industrial, commercial, and domestic use. All sourced from industry-leading brands including Schurter, Littelfuse, Cooper Bussmann, and Mersen.
How Fuse Holders Work
Fuse holders securely retain and protect fuses, ensuring a stable connection within the electrical circuit. When a fuse needs replacement, the fuse carrier or fuse housing allows for easy access and removal without disrupting the entire system. This ensures quick and safe maintenance of electrical components.
Types of Fuse Holders
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 fuse holder 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.
Benefits of Electrical Fuse Holders
Electrical fuse holders offer key benefits that make them essential in various applications.
- Protection and Safety: Fuse holders provide a secure housing for fuses, protecting them from environmental factors and ensuring safety by preventing accidental contact with live circuits.
- Easy Maintenance: The design of fuse holders and carriers, allows for quick and easy replacement of fuses without disrupting the entire system, reducing downtime.
- Versatility: Available in various fuse mounting types, such as panel mount, PCB mount, and DIN rail mount, electrical fuse holders can be used in a wide range of industrial, commercial, and domestic applications.
- Enhanced Durability: High-quality fuse holders mounts are made from robust materials, keeping the fuse in place, secure and ready when it needs to be.
- Compatibility: Fuse holders are designed to accommodate different types of fuses, providing flexibility and compatibility with various electrical systems and applications.
Industrial Applications of Fuse Holders
Fuse holders help protect employees and equipment from electrical shocks by providing reliable fuse mounting for easy fuse replacement or inspection. They can be found in the following industries:
- Manufacturing Equipment: Fuse holders are used to protect motors, drives, and control systems from overcurrent conditions, ensuring uninterrupted production and minimising downtime.
- Power Distribution: In power distribution panels, power fuse holders secure high-capacity fuses that safeguard transformers and power lines from faults and overloads.
- Automotive Industry: Electrical fuse holders are critical in vehicles, protecting circuits in lighting, ignition systems, and electronic control units from potential damage.
- Telecommunications: In telecom equipment, fuse holders protect sensitive communication circuits from power surges, ensuring reliable data transmission and connectivity.
- HVAC Systems: Fuse holders in HVAC units prevent electrical faults in compressors, fans, and control boards, ensuring efficient and safe operation.
How to Choose the Right Fuse Holder for Your Needs
If you’re looking to buy a fuse holder, consider the type of fuse you are using and the environment in which it will operate. This will affect the size and material of the fuse housing. Additionally, think about how you will mount the fuse holder, such as panel mount or DIN rail mount, and ensure the fuse holder fits your space.
