Main Technical Specifications

Selection & Application Guide

When selecting a PCB mount automotive fuse holder, first confirm the fuse size, system rated voltage and working current. For automotive and low-voltage industrial systems, ATO standard specification is the most universal choice. Always select a fuse with appropriate current rating according to the actual working current of the circuit, and reserve a 1.25-1.5 times safety margin to avoid overheating under long-term operation. For high-temperature environments above 60℃, derate the current appropriately to ensure long-term reliable operation. The plug-in through-hole structure is compatible with automated wave soldering processes, which can effectively improve production efficiency and reduce assembly costs for mass production projects.

Application Scenarios

• Automotive electronic control units and on-board circuit protection
• New energy vehicle auxiliary circuits and on-board charger systems
• Industrial control boards and automation equipment power modules
• Commercial vehicle and engineering machinery electrical systems
• RVs and yacht DC power distribution circuit boards
• Telecom base stations and communication power supply equipment
• Power supply modules and DC-DC converter protection

Installation & Usage Notes

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

2. Insert the fuse holder pins into the corresponding PCB holes, and ensure proper soldering quality to avoid cold solder joints that cause increased contact resistance and overheating.

3. Insert the fuse vertically into the holder and ensure it is fully seated and clamped firmly.

4. Do not use the fuse holder 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. For applications with strong vibration, add fixing glue or reinforcement structure if necessary to further improve anti-loosening performance.

7. Store the product in a dry and dust-free environment to prevent terminal oxidation and insulation performance degradation.
