Main Technical Specifications

Selection & Application Guide

When selecting a vertical PCB mount fuse holder, 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. Select a 10x38mm fuse with appropriate current rating according to the actual load, and reserve a 1.25-1.5 times safety margin to avoid overheating under long-term operation. For high-density PCB designs, vertical mounting models are recommended to save valuable board space. The through-hole structure is compatible with automated wave soldering processes, which can effectively improve assembly efficiency and reduce production costs for mass production projects.

Application Scenarios

• Solar photovoltaic inverters and PV combiner box circuit protection
• Battery energy storage systems (ESS) and BMS auxiliary circuits
• Industrial high-voltage power supplies and power distribution equipment
• Charging piles and new energy auxiliary power systems
• Telecom base stations and communication power equipment
• Test instruments and laboratory high-voltage power supplies
• Industrial automation control cabinets and medium-voltage distribution units

Installation & Usage Notes

1. Select a matching 10x38mm cartridge 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 fully into the vertical clip to ensure reliable contact, preventing loosening and poor contact caused by vibration.

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. Avoid repeated excessive bending of the terminals to prevent elastic fatigue and reduced clamping force.

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