Product Information
Full details
The Weidmuller 1011300000 WSI Fuse Clamp is designed for electrical engineers and technicians needing a reliable and easy-to-use solution for protecting circuits with 5 x 20 mm fuses. Its key benefit is the swiveling fuse holder combined with maintenance-free screw connections, ensuring quick and safe fuse replacement and secure mounting. A potential caveat is its specific voltage and current rating, which must be matched to the application's requirements. This terminal block offers a clear LED error indicator with low leakage current, supporting conductor sizes from 0.5 to 10 mm².

FAQs
What type and size of fuse does the Weidmuller 1011300000 use?
This fuse clamp is designed for standard 5 x 20 mm tube fuses.
What is the maximum conductor size that can be connected?
The clamp supports conductor cross-sections ranging from 0.5 mm² up to 10 mm².
What is the rated voltage and current for this fuse clamp?
The clamp has a voltage rating of 36 V AC/DC and a rated current of 6.3 A.
Does the LED indicator require a separate power source?
No, the LED indicator is powered by the circuit itself and has an extremely low leakage current.
How is the fuse replaced?
The fuse holder swivels open, allowing for easy and safe fuse replacement without needing to remove the clamp from its mounting.
What are the dimensions of the fuse clamp?
The dimensions are 7.9 mm in width, 71.5 mm in depth, and 60 mm in height.
Is this product suitable for outdoor use?
While it has a wide operating temperature range, its suitability for outdoor use depends on environmental factors like moisture and direct exposure to elements. Always ensure proper enclosure if used in exposed conditions.
Troubleshooting
LED indicator does not light up when fuse is blown.
Verify the fuse is correctly seated in the holder. Ensure the fuse itself is functional and not damaged. Check that the LED is not obstructed and confirm the circuit is receiving power within the specified voltage range.
Conductor connection feels loose.
Re-open the screw terminal and ensure the conductor is fully inserted. Tighten the screw firmly, ensuring proper torque to secure the connection without damaging the conductor.
Fuse repeatedly blows.
This indicates an underlying circuit issue. Check for short circuits, overloaded components, or incorrect fuse rating for the application. The clamp itself is unlikely to be the cause; focus on the protected circuit.
Clamp exhibits signs of overheating.
Immediately disconnect power and inspect the clamp and circuit. Overheating typically suggests the circuit is drawing current exceeding the clamp's rated 6.3 A, or a poor connection is causing resistance. Replace the clamp if damaged and address the circuit overload.
Pros and Cons
Pros
- Easy and safe fuse replacement due to the swiveling holder.
- Maintenance-free screw connections reduce long-term upkeep.
- Clear LED indicator for quick status checks.
- Wide range of compatible conductor sizes (0.5-10 mm²).
- Robust operating temperature range (-50°C to +120°C).
- Space-saving narrow design.
Cons
- Limited to 5 x 20 mm fuse sizes.
- Rated current of 6.3 A may be insufficient for high-power applications.
- Voltage rating of 36 V AC/DC limits use in higher voltage systems.
- Requires screw termination, which might be less preferred than push-in terminals in some environments.
- Specific beige color may not fit all aesthetic requirements.
Setup, Compatibility & Care Instructions
Setup:
- Ensure the power to the circuit is completely disconnected.
- Select the appropriate conductor (0.5 to 10 mm²) and strip the end to the correct length for screw terminals.
- Insert the conductor into the designated screw terminal and tighten the screw firmly to secure the connection.
- Insert a 5 x 20 mm fuse into the swiveling fuse holder.
- Close the fuse holder and re-apply power to the circuit.
Compatibility:
- Fuse Type: Exclusively designed for 5 x 20 mm tube fuses.
- Conductor Size: Compatible with solid and stranded conductors ranging from 0.5 mm² to 10 mm².
- Voltage/Current: Suitable for circuits operating at up to 36 V AC/DC with a maximum rated current of 6.3 A.
Care:
- This product requires minimal care due to its maintenance-free screw connections.
- Periodically inspect the fuse and the clamp for any signs of physical damage or corrosion.
- Ensure the area around the clamp is kept free of excessive dust and debris to maintain optimal performance of the LED indicator.
- Clean the exterior of the clamp with a dry or slightly damp cloth; avoid using solvents or abrasive cleaners.
