Universal Five by Twenty Millimeter Inline Fuse Holder Ensuring Robust Protection Across Glass Tube Fuse Installations

In modern electronic assemblies, safeguarding circuits against overcurrent events remains a top priority. The 5x20mm inline fuse holder simplifies this task by allowing technicians and hobbyists to integrate a removable protective element into wiring harnesses. Featuring universal accommodation for standard glass tube fuses, it suits a wide range of electrical designs. Its compact footprint and straightforward installation process reduce downtime and enhance system longevity. The holder’s durable construction ensures reliable electrical continuity under normal operating conditions, while facilitating rapid fuse replacement whenever maintenance is required.

Design and Dimensions

In terms of structure, the inline fuse holder employs high-grade nylon or polycarbonate housing for robust mechanical support. The snap-on cap design secures standard 5x20mm glass tube fuses, preventing unintended dislodgment during vibration or mechanical stress. The holder accommodates wire gauges from 18 to 22 AWG, terminating in tin-plated brass contacts that resist corrosion and maintain low contact resistance. Overall dimensions of approximately 28mm in length and 8mm in diameter make it suitable for confined spaces, while color-coded housing options assist in circuit identification during complex assemblies.

Performance and Durability

Temperature resilience is a key attribute of this inline fuse holder, with operating limits commonly ranging between -40°C and +125°C. The insulating material is flame-retardant to UL 94 V-2 standards, enhancing safety under fault conditions. Contacts are precision-machined and plated to withstand repetitive insertion cycles without significant degradation. Typical current ratings span from 0.5A up to 10A, with voltage tolerances reaching 250V AC or equivalent DC ratings. These specifications ensure consistent protection across residential, automotive, and industrial power distribution systems.

Application Scenarios

The 5x20mm inline fuse holder excels in diverse environments. In automotive wiring harnesses, it protects lighting and audio circuits against short circuits. In renewable energy installations, it safeguards inverters and charge controllers in solar power systems. Industrial control panels benefit from quick fuse replacement during scheduled maintenance, minimizing operational interruptions. DIY enthusiasts leverage the holder in prototype boards and robotics platforms, where modularity and ease of service are crucial. Its adaptability extends to marine electronics, where moisture-resistant variants ensure long-term reliability.
