When it may not be suitable

This fuse is not intended for use in low-voltage residential AC circuits or applications where the current exceeds the 10A rating. It is specifically designed for GPV (photovoltaic) applications and may not provide the correct protection characteristics for general-purpose household appliances or automotive electrical systems.

Key specifications

• Dimensions: 10x38mm
• Rated voltage: 1000V DC
• Rated current: 10A
• Application category: GPV (Photovoltaic)
• Quantity: 1 unit per package

How to use

The fuse should be installed into a compatible 10x38mm fuse holder designed for high-voltage DC applications. Ensure that the power supply is completely disconnected before insertion to prevent electrical shock. Align the fuse with the holder contacts and press firmly until it is securely seated. Regular inspection of the fuse holder and the fuse itself is recommended to ensure there is no corrosion or physical damage that could impede performance.

What to consider before purchase

• Verify that the 10A current rating matches your system requirements.
• Ensure your fuse holder is rated for 1000V DC operation.
• Confirm that the application is a photovoltaic system requiring GPV-rated protection.
• Check the physical space constraints in your electrical cabinet for the 10x38mm size.

Usage recommendations

Always replace the fuse with an identical model to maintain the safety standards of your electrical system. Never attempt to bypass or repair a blown fuse, as this poses a significant fire and safety risk.
