It is manufactured in accordance with EN/IEC 60127-2 standards, guaranteeing consistent performance and safety in both industrial and domestic environments.

Advantages

This fuse offers a high rupture capacity of 1500 Amps, which allows it to safely interrupt significant fault currents without compromising the integrity of the surrounding electrical system. Its compact 5x20mm design makes it a versatile component for integration into space-constrained devices. The ceramic construction provides superior thermal stability compared to standard glass fuses, making it a robust choice for demanding applications where reliability is critical.

Suitable for

• Dimmers and lighting control systems
• Viking terminal blocks
• Emergency lighting units
• Electrical transformers
• Sensitive electronic control circuits

When it may not be suitable

This fuse is not intended for high-power applications that consistently exceed a 0.5A current draw, as it will trigger an immediate circuit interruption. It is also not suitable for environments where the operating voltage exceeds the 250V rating.

Key specifications

• Dimensions: 5x20mm
• Rated current: 0.5A
• Rated voltage: 250V
• Rupture capacity: 1500A
• Body material: Ceramic
• Response type: Instant reaction
• Compliance: EN/IEC 60127-2

How to use

To install the fuse, ensure the power supply to the device or circuit is completely disconnected. Locate the fuse holder within your equipment, remove the old or blown fuse, and insert the Legrand 010205 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 0.5A current rating matches the requirements of your specific device.
• Ensure the physical dimensions of 5x20mm are compatible with your existing fuse holder.
• Check that the operating voltage of your circuit does not exceed 250V.

Usage recommendations

Always replace a blown fuse with one of the exact same rating and characteristics to maintain the safety and functionality of your electrical equipment. Never attempt to bypass or bridge a fuse, as this creates a significant fire and safety hazard.
