Selection & Application Guide
When selecting a 10x38mm PCB mount fuse holder, first confirm the system rated voltage, working current and fuse size. For high-voltage DC scenarios such as solar photovoltaic systems, PPS housing with better high-voltage insulation is recommended; for general industrial power supplies, PBT housing can meet the demand with higher cost performance. The contact material can be selected between brass and red copper according to current level and conductivity requirements. Always ensure that the rated voltage of the fuse holder is higher than the actual working voltage of the circuit, and reserve sufficient safety margin for current to avoid overheating under long-term operation.
Application Scenarios
- Solar photovoltaic inverters and PV combiner boxes (core solar application)
- High-voltage DC power supplies and charging systems
- Industrial control equipment and high-voltage instrumentation
- New energy power distribution and energy storage auxiliary circuits
- Telecom power supply and base station high-voltage protection
- LED high-voltage drive power supply
- Household and commercial photovoltaic power generation systems
Installation & Usage Notes
1. Select a matching 10x38mm high-voltage fuse with appropriate current and voltage rating before installation.
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 accidents.
4. Disconnect the power supply before replacing the fuse to prevent electric shock and short-circuit damage to high-voltage circuits.
5. Store in a dry, dust-free environment to prevent contact oxidation and insulation performance degradation.
6. For high-humidity and high-dust environments, it is recommended to select models with higher protection level or apply conformal coating treatment.
