Key benefits Reliable overcurrent protection for a wide range of electronics projects and repairs. Clear glass body with metal end caps lets you visually confirm a blown element for fast diagnostics and replacement. Broad set of common sizes and current ratings increases compatibility across power adapters, supplies, and hobby circuits. What’s in the pack 10 glass fuse tubes in common sizes, including 5x20 mm and 6x30 mm, ready for use in many electronics projects. Includes a 5x20 mm fuse rated at 10A. Electrical specifications Voltage rating: up to 250 V. Current ratings available in the set range from 0.5 A to 20 A (examples: 0.5A, 1A, 2A, 3A, 3.15A, 4A, 5A, 6A, 7A, 8A, 10A, 12A, 15A, 20A). Form, materials, and compatibility Glass tube construction with metal end caps and a clear body so you can see if the fuse element has blown. 5x20 mm fuses fit standard 5x20 mm fuse holders; the pack contains common sizes for standard holders used in consumer and hobby electronics. Why this product helps Protects equipment from overcurrent events, preventing damage to power supplies, drivers, and connected circuits. Standard sizes and visible fuse element make troubleshooting and replacement quick and straightforward. Multiple current ratings let you match protection to the device’s normal operating current. Typical use scenarios Replacing a blown fuse in a laptop power adapter, DC bench supply, or small consumer power brick. Protecting LED drivers, audio equipment, and other household electronics during repairs or installations. Prototyping and hobby work on 12 V automotive circuits, Arduino projects, or other low-voltage systems where replaceable fuses are required. How to choose the right fuse Select a current rating just above your normal operating current to avoid nuisance blows while still providing protection. Ensure the fuse voltage rating (250 V max in this pack) meets or exceeds your supply voltage. Use the included 5x20 mm 10A fuse as a common option for higher-limit protection where appropriate. Practical tips Replace blown fuses with the same size and equivalent current/voltage rating. Inspect the glass body to confirm a blown element before replacing to avoid masking underlying faults.
