Mersen X1014573 Cylindrical Ultra-Fast Full-Range Fuse gR 690VAC 10x38 5A

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.
