1. Introduction
This manual provides essential information for the safe and effective use of Legrand LEG92923 10A Cartridge Fuses. These fuses are designed for the protection of electrical circuits against short circuits. Please read this manual thoroughly before installation and use.
2. Safety Information
WARNING: Risk of electric shock. Always disconnect power before installing or replacing fuses.
- Ensure the fuse rating matches the circuit requirements. Using an incorrect fuse rating can lead to fire or damage to equipment.
- Only qualified personnel should perform electrical work.
- Do not attempt to repair a blown fuse. Replace it with a new one of the same type and rating.
- Keep fuses out of reach of children.
3. Product Overview
The Legrand LEG92923 is a set of three domestic cylindrical cartridge fuses, each rated at 10 Amperes. They feature an indicator for easy identification of a blown fuse. These fuses are designed to interrupt the flow of excessive current, thereby protecting electrical appliances and wiring from damage due to overcurrents or short circuits.

4. Setup and Installation
These cartridge fuses are designed for through-hole mounting in appropriate fuse holders or fuse boxes. Follow these general steps for installation:
- Disconnect Power: Before beginning any work, ensure that the main power supply to the circuit is completely disconnected at the circuit breaker or main switch. Verify with a voltage tester.
- Identify Fuse Holder: Locate the fuse holder where the new fuse needs to be installed or the old fuse needs to be replaced.
- Insert Fuse: Carefully insert the Legrand LEG92923 cartridge fuse into the designated fuse holder. Ensure it is seated firmly and correctly.
- Restore Power: Once the fuse is securely in place, restore power to the circuit.
Consult your appliance or electrical panel manual for specific fuse holder types and installation procedures.
5. Operating Principle
Legrand LEG92923 cartridge fuses operate as sacrificial devices designed to protect electrical circuits. When an overcurrent condition (such as a short circuit) occurs, the metallic element inside the fuse melts due to the excessive heat generated. This melting action breaks the circuit, stopping the flow of electricity and preventing damage to the connected equipment or wiring. The integrated indicator provides a visual cue when the fuse has blown.
6. Maintenance
Fuses are maintenance-free components. They are designed for single-use protection. If a fuse blows, it must be replaced. Do not attempt to repair or bypass a blown fuse.
Fuse Replacement:
- Disconnect Power: Always turn off the power to the circuit before attempting to replace a fuse.
- Identify Blown Fuse: The indicator on the Legrand LEG92923 fuse will show if it has blown.
- Remove Old Fuse: Carefully extract the blown fuse from its holder.
- Install New Fuse: Insert a new Legrand LEG92923 fuse (10A, 10.3 x 25.8 mm) into the holder, ensuring it is correctly seated.
- Restore Power: Turn the power back on. If the new fuse blows immediately, there may be an underlying electrical fault that requires professional attention.
7. Troubleshooting
If a circuit stops working, the first step is often to check the fuse. If a Legrand LEG92923 fuse has blown (indicated by its internal indicator), it means it has successfully protected the circuit from an overcurrent event.
- Fuse Blows Immediately After Replacement: This indicates a persistent short circuit or overload in the electrical system. Do not continue to replace fuses without addressing the root cause. Disconnect the appliance or circuit and consult a qualified electrician.
- No Power, Fuse Appears Intact: Check other components in the circuit, such as the circuit breaker or the appliance itself. The issue might not be fuse-related.
Always prioritize safety. If you are unsure about any electrical issue, contact a professional electrician.
