Legrand 010263 Cylindrical Safety Fuse 5x20mm 6.3A 250V

The Legrand 010263 is a professional-grade cylindrical safety fuse designed to provide reliable overcurrent protection for a wide range of electrical circuits. With its compact 5x20mm dimensions and robust ceramic body construction, this fuse is engineered to meet stringent safety standards, ensuring consistent performance in demanding environments. It features a high rupture capacity, making it an essential component for safeguarding sensitive electronic equipment and industrial systems from potential damage caused by electrical faults.

Advantages

This safety fuse offers exceptional reliability due to its high rupture capacity of 1500 Amps, which allows it to safely interrupt significant fault currents. The ceramic body design provides superior thermal stability and durability compared to standard glass fuses, ensuring that the component remains intact even under challenging operating conditions. By conforming to international EN/IEC 60127-2 standards, the product guarantees compatibility and safety, providing peace of mind for both residential and industrial electrical installations.

Suitable for

• Dimmers and lighting control systems
• Viking terminal blocks
• Emergency lighting units
• Electrical transformers
• General electronic circuit protection

When it may not be suitable

This fuse is not intended for use in circuits where the operating current consistently exceeds 6.3 Amps, as this will lead to premature blowing. It is also not suitable for applications requiring a slow-blow or time-delay characteristic, as this is an instant reaction fuse designed for rapid circuit interruption.

Key specifications

• Dimensions: 5x20mm
• Rated Current: 6.3 Amps
• Rated Voltage: 250 Volts
• Rupture Capacity: 1500 Amps
• Body Material: Ceramic
• Type: Instant reaction (fast-acting)

How to use

To install the fuse, ensure that the power supply to the circuit is completely disconnected to prevent accidental contact with live components. Locate the fuse holder within your device or terminal block, remove the old or damaged fuse, and insert the Legrand 010263 into the clips. Ensure the fuse is seated firmly and that the holder is properly closed before restoring power to the system.

What to consider before purchase

• Verify that the current rating of 6.3A matches the requirements of your specific device.
• Ensure the physical dimensions of 5x20mm are compatible with your existing fuse holder.
• Confirm that your application requires a fast-acting (instant reaction) fuse rather than a time-delay type.

Usage recommendations: Always replace a blown fuse with one of the exact same rating and type to maintain the safety integrity of your electrical equipment. Do not attempt to bypass or bridge a fuse, as this creates a significant fire and safety hazard.
