Fuse Holders

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 categorised by their attachment or mounting type.

Types of Fuse Holders

There are different types of fuse holders, depending on the fuse it is designed to accommodate, its application, and the environment it will be used in. Some of the most common types you will find are:

Base Mount

In this type of fuse holder, the base of the holder is usually attached to a surface by fixing screws in the centre of the base. Base mount fuse holders are typically used with cartridge fuses.

Inline Fuse Holders

Inline fuse holders provide housing for a fuse in a wiring circuit. A cable or wire is attached at each end of the holder, making the in-line connection easy. Inline fuse holders in NZ are often used in vehicle electrical circuits with mini blade fuses.

Panel Mount

Panel mount fuse holders are 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

Fuse 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.

Key Features and Benefits of Fuse Holders

Variety of Mounting Options

Fuse holders come in various mounting styles, such as panel mount, DIN rail mount, PCB mount, and inline fuse holders, to accommodate different installation requirements and spaces.

Durability and Protection

• Fuse holders are made of robust materials like ceramic, plastic, metal, or even glass, ensuring long-term use in harsh environments and protecting against electrical hazards.
• They often feature covers or enclosures to prevent accidental contact with live components.

Versatility

• Fuse holders, including specialised DC fuse holders, are compatible with various fuse types and sizes, allowing for flexibility in circuit protection designs and easy fuse replacement.
• They can be used across various applications, including industrial machinery, automotive electronics, and household appliances, providing reliable circuit protection.

Applications of Fuse Holders

Fuse holders, providing essential circuit protection, are employed across a diverse range of applications:

Industrial Equipment Protection

• Fuse holders safeguard critical machinery and processes from electrical faults, preventing damage and downtime.
• Enable quick and easy fuse replacement for minimal disruption to operations.

Vehicle Electrical Systems

• Protect sensitive automotive electronics from power surges and short circuits.
• Ensure the safety and reliability of various vehicle systems, including lighting, ignition, and entertainment.

Commercial Power Distribution Systems

• Fuse holders provide localised circuit protection in commercial buildings, safeguarding electrical infrastructure and minimising the impact of faults.
• Facilitate maintenance and troubleshooting by allowing for easy isolation and replacement of faulty fuses.

Domestic Electrical Panels

• Act as the first line of defence in household electrical systems, protecting against overcurrents and short circuits.
• Fuse holders help prevent electrical fires and ensure the safety of residents and property.
