Fast-Blow Glass Fuse Assortment Kit – 180 Pieces, 24 Values, 250V
Having the correct replacement fuse available can make electrical equipment maintenance more convenient. The Upvivi Fast-Blow Glass Fuse Assortment Kit provides a selection of glass tube fuses in different current ratings and two commonly used sizes.
This assortment contains 180 pieces covering 24 different fuse ratings. It includes 5x20mm and 6x30mm glass fuses, each rated for 250V according to the product description. The included labelled storage box helps keep the different fuse values organised.
Product Overview
Glass tube fuses are designed to help protect compatible electrical circuits against excessive current. A fast-blow fuse is intended to open the circuit quickly when current exceeds its specified operating characteristics.
This kit offers a range of current ratings from 0.5A to 20A in two physical sizes. The fuse bodies are made from glass, while the end caps are described as nickel-plated brass.
With multiple ratings in one package, the assortment can be useful for repair work, maintenance tasks and keeping suitable replacement fuses available. However, choosing the correct fuse requires more than matching its physical size or voltage rating.
Key Features
1. 180-Piece Assortment
The kit contains 180 glass fuses across 24 different current ratings. This selection provides several replacement options for equipment that uses compatible glass tube fuses.
2. Two Common Fuse Sizes
The assortment includes 5x20mm and 6x30mm fuses. Having both sizes available can be useful when maintaining different compatible devices, provided the fuse holder is designed for the selected size.
3. 24 Current Ratings
Each size is available in 12 ratings, ranging from 0.5A to 20A. This gives users a selection of current ratings for matching the original equipment specification.
4. 250V Voltage Rating
The product description specifies a 250V rating for the fuses. The replacement fuse must still meet or exceed the equipment manufacturer’s required voltage and other electrical specifications.
5. Glass Tube Construction
The fuse body is made from glass, with nickel-plated brass end caps according to the listing. The glass construction also allows the fuse element to be visually inspected, although appearance alone cannot confirm whether a fuse is electrically sound.
6. Labelled Storage Box
The fuses are supplied in a sturdy box with labelled models, helping users identify and organise different ratings and sizes more easily.
Fuse Ratings and Quantities
The kit contains the following 12 current ratings in each of its two sizes:
| Fuse Size | Current Ratings | Quantity |
|---|---|---|
| 5x20mm | 0.5A, 1A, 2A, 3A, 4A, 5A, 6A, 7A, 8A, 10A, 15A, 20A | 10 pieces per rating (120 total) |
| 6x30mm | 0.5A, 1A, 2A, 3A, 4A, 5A, 6A, 7A, 8A, 10A, 15A, 20A | 5 pieces per rating (60 total) |

Potential Uses
- Replacing compatible glass tube fuses in electronic equipment.
- Electrical equipment maintenance and repair.
- Keeping a selection of replacement fuse ratings in a workshop.
- Servicing compatible appliances and devices that specify these fuse dimensions and ratings.
- Organising replacement fuses for electronics projects and suitable repair work.
Important Fuse Selection and Safety Advice
Always match the original fuse specification. Before replacing a fuse, check the equipment manual, original fuse markings and manufacturer’s requirements. The correct replacement must match the required current rating, voltage rating, physical dimensions, fast-blow characteristic and any specified breaking-capacity or safety approvals.
- Do not replace a fuse with a higher amp rating simply because the original fuse keeps blowing.
- Never assume that two fuses are interchangeable just because they have similar dimensions.
- Disconnect equipment from its power source before attempting replacement, and follow the manufacturer’s instructions.
- Do not touch exposed electrical components or attempt repairs on live equipment.
- A fuse that repeatedly blows may indicate an underlying fault that needs professional inspection.
- The listing does not provide a breaking-capacity rating or independent certification details, so verify these requirements before using a fuse in safety-critical equipment.
- For mains-powered equipment, use a suitably qualified person if you are unsure about the correct replacement or installation.
Final Thoughts
The Upvivi Fast-Blow Glass Fuse Assortment Kit provides 180 fuses across 24 current ratings and two sizes: 5x20mm and 6x30mm. Its labelled storage box helps keep the different options organised and accessible for compatible repair and maintenance tasks.
It may be a practical addition to an electronics workbench or maintenance kit. The most important consideration is selecting a fuse that exactly matches the equipment manufacturer’s electrical and safety requirements rather than choosing one based only on its size or amp rating.
