## Long description

The Mersen X1014573 is a high-performance cylindrical ultra-fast full-range fuse, specifically engineered to provide superior circuit protection for sensitive power electronics. With a 5A current rating and a 690VAC voltage capacity, this 10x38 mm fuse is designed to safeguard power semiconductors and critical electrical components against short circuits and overcurrent conditions in demanding industrial environments.
Advantages
This fuse offers exceptional reliability due to its ultra-fast response time, which is essential for protecting delicate semiconductor devices from damage during fault events. Its full-range gR classification ensures that the fuse can interrupt both low-level overloads and high-level short circuits effectively. The compact 10x38 mm cylindrical design allows for easy integration into standard fuse holders, making it a versatile choice for modern power distribution and control systems where space and performance are critical.
Suitable for
Power semiconductor protection
Industrial power distribution systems
Control and automation equipment
Variable frequency drives and soft starters
Sensitive electronic circuitry
When it may not be suitable
This fuse is not intended for general-purpose residential electrical applications or standard lighting circuits where ultra-fast tripping characteristics are not required. It is specifically optimized for semiconductor protection and may not provide the desired performance in circuits with high inrush currents that are not associated with fault conditions.
Key specifications
Rated current: 5A
Rated voltage: 690VAC
Fuse class: gR (full-range)
Form factor: 10x38 mm
Design: Cylindrical ultra-fast
How to use
The fuse should be installed into a compatible 10x38 mm fuse holder or disconnect switch designed for industrial applications. Ensure the power is completely disconnected before installation to prevent electrical shock. Insert the fuse firmly into the clips, ensuring proper contact. Verify that the circuit voltage and current requirements match the fuse ratings before energizing the system.
What to consider before purchase
Verify the current and voltage requirements of your specific application
Ensure the fuse holder is compatible with 10x38 mm cylindrical fuses
Confirm that the gR class is appropriate for your semiconductor protection needs
Usage recommendations
Always replace the fuse with one of the exact same rating and class to maintain the integrity of the protection system. Do not attempt to repair or bypass a blown fuse.
