Core Advantages
Dual Specification Compatibility
One fuse holder supports both 5×20mm and 6×30mm standard cartridge fuses, which reduces the number of SKUs required for procurement and inventory, simplifies BOM management, and effectively lowers production and operation costs for equipment manufacturers.
Stable Electrical Performance
Equipped with high-purity brass tin-plated contacts, it effectively reduces contact resistance, avoids abnormal heating during long-term current transmission, and ensures stable operation of the circuit. The low-resistance design also improves the overall energy efficiency of electrical equipment.
Flame Retardant & High Temperature Resistance
The housing is made of flame retardant PBT engineering plastic, which will not deform or ignite even in high temperature working environments. It can effectively isolate circuit faults and prevent safety risks such as short circuits and fire spread.
Easy Installation & Maintenance
Through-hole soldering design ensures firm combination with the circuit board, with stable structure and strong shock resistance. The open structure allows quick fuse replacement, simplifying later equipment maintenance and reducing maintenance costs.
Application Scenarios
- Industrial power supplies, inverters and charging equipment
- New energy photovoltaic and energy storage auxiliary systems
- Automotive electronic control units and on-board circuits
- Household appliances and small electrical equipment
- Communication equipment and precision instrumentation
- Industrial automation control panels and power distribution modules
Installation & Usage Notes
1. Select the appropriate fuse specification and current rating according to the actual circuit protection requirements.
2. Ensure proper soldering quality during through-hole installation to avoid cold solder joints that cause increased contact resistance and overheating.
3. Do not use the fuse holder beyond its rated voltage and current range to prevent insulation breakdown and safety hazards.
4. Disconnect the power supply before replacing the fuse to avoid electric shock and short-circuit damage to the circuit.
5. Store in a dry, dust-free and corrosion-free environment to prevent contact oxidation and insulation performance degradation.
6. For high-temperature and high-humidity environments, select products with higher flame retardant grade and corrosion-resistant treatment.
