Designed with a compact 10x38mm form factor, this gR class fuse is specifically optimized for the protection of power electronics and semiconductor devices. With a rated voltage of 690VAC and a current rating of 25A, it ensures reliable operation and rapid response times in demanding industrial environments where equipment safety is paramount.

Advantages

This fuse offers exceptional performance due to its ultra-fast acting characteristics, which are essential for safeguarding expensive semiconductor components from short circuits and overcurrent conditions. Its full-range gR class classification ensures that it can handle both overload and short-circuit protection effectively. The robust construction and standardized 10x38mm dimensions allow for easy integration into existing fuse holders and electrical panels, providing a reliable solution for modern power conversion systems.

Suitable for

• Power electronics protection
• Semiconductor device safeguarding
• Industrial automation systems
• Frequency converters and inverters
• Soft starters and power supplies

This fuse is not intended for general-purpose residential electrical circuits or standard household appliances. It is specifically designed for high-speed semiconductor protection and may not provide the correct tripping characteristics for standard motor branch circuits or general distribution lines where slower-acting fuses are typically required.

Key specifications

• Dimensions: 10x38mm
• Rated current: 25A
• Rated voltage: 690VAC
• Fuse class: gR
• Application type: Ultra-fast, full-range

To install the Mersen F1014581, ensure the power supply is completely disconnected from the circuit. Insert the fuse into a compatible 10x38mm fuse holder or disconnect switch, ensuring that the contact points are clean and secure. Verify that the fuse rating matches the requirements of the equipment being protected before restoring power to the system.

What to consider before purchase

• Verify that the 25A current rating matches your circuit requirements
• Ensure the fuse holder is compatible with 10x38mm cylindrical fuses
• Confirm that the application involves semiconductor or power electronics protection
• Check that the system voltage does not exceed 690VAC

For optimal safety and longevity, always replace fuses with the exact same type and rating. Regularly inspect fuse holders for signs of oxidation or heat damage to ensure a reliable electrical connection.
