PCB Fuse Clip | Dual 5x20mm 6x30mm 16A 1000V AC/DC

The PCB fuse clip with dual-size design is a high-voltage through-hole circuit protection component compatible with both 5x20mm and 6x30mm cartridge fuses. This PCB fuse clip adopts high-elasticity nickel-plated brass conductive contacts and a flame-retardant insulating base, delivering stable electrical connection and reliable overcurrent protection for high-voltage AC and DC printed circuit boards.</p>

Key Features of Dual Size PCB Fuse Clip

• Dual compatibility: fits both standard 5×20mm and 6×30mm cartridge fuses, reducing BOM and inventory costs
• High voltage rating: 1000V AC/DC withstand, 16A rated current, suitable for high-voltage low-current circuits
• Contact material: High-elasticity nickel-plated brass, tight clamping force, low contact resistance, stable conductivity
• Flame-retardant insulating base, excellent insulation performance, high temperature and aging resistance
• Through-hole THT mounting, compatible with wave soldering and manual soldering, easy for mass production
• Compact structure, small footprint, saves PCB layout space for high-density board design
• Wide operating temperature range, adapts to harsh industrial and outdoor working environments
• RoHS compliant, suitable for global electronic product export

Compared with single-specification fuse holders, this dual-compatible fuse clip eliminates the need for multiple models in production and maintenance, effectively reducing procurement types and inventory pressure. Its high-elastic metal contact structure maintains stable clamping force and low contact resistance even after multiple fuse replacements, ensuring long-term reliable operation of the circuit.

Main Technical Specifications

Selection & Application Guide

When selecting a PCB fuse holder clip, first confirm the fuse size, system rated voltage and working current. For high-voltage circuits above 500V, products with sufficient voltage withstand rating must be selected to avoid insulation breakdown risks. For applications requiring multiple fuse specifications, this dual-size model is the preferred choice as it can adapt to 5x20mm and 6x30mm fuses with one component, simplifying design and procurement. Always match the fuse rating with the actual working current of the circuit, reserving a 1.25-1.5 times safety margin to avoid premature fuse failure or insufficient protection. For high-temperature and high-humidity environments, nickel-plated contacts are recommended for better oxidation resistance and longer service life.

Application Scenarios

• Switching power supplies, high-voltage power modules and charger circuits
• Industrial control equipment and automation control boards
• LED lighting drivers and commercial lighting power systems
• Household appliances and small electrical equipment control circuits
• Communication power supplies and network equipment protection
• Test instruments and laboratory power supply circuits
• New energy auxiliary circuits and low-voltage distribution modules

Installation & Usage Notes

1. Select a matching cartridge fuse with appropriate current and voltage rating according to circuit protection requirements.

2. Ensure proper soldering quality during through-hole THT installation to avoid cold solder joints that cause increased contact resistance and overheating.

3. Insert the fuse fully into the clip to ensure reliable contact, preventing loosening and poor contact caused by vibration.

4. Do not use the fuse clip beyond its rated voltage and current range to prevent insulation breakdown and safety hazards.

5. Disconnect the power supply before replacing the fuse to avoid electric shock and short-circuit damage to the circuit.

6. Store the product in a dry environment with temperature between 0℃ and 60℃ and relative humidity below 70% to prevent contact oxidation and performance degradation.
