Product Information
Full details
This Weidmüller 0474560000 terminal block is designed for electricians and automation engineers needing a reliable component for circuit protection and power distribution. Its key benefit is the maintenance-free, swiveling fuse holder that allows for quick and safe fuse replacement. A minor caveat is that it requires a closing plate for completion of the assembly. This block features a screw connection for easy installation, supports pipe fuses of 5 x 20/25 mm, and is suitable for conductors ranging from 0.5 to 4mm².

FAQs
What type of fuses does this terminal block support?
This terminal block supports G-fuse inserts of size 5 x 20 mm and 5 x 25 mm.
Does the screw connection require periodic tightening?
No, the screw connection is designed to be maintenance-free and does not require re-tightening after installation.
What is the maximum conductor size that can be connected?
The terminal block can accommodate conductor cross-sections from 0.5 mm² up to 4 mm², including fine-strand, solid-core, and multi-wired conductors.
Is a closing plate included with the terminal block?
No, a closing plate is required for the assembly but is not included with the terminal block itself. It must be purchased separately.
What is the operating temperature range?
The terminal block can operate reliably in a wide temperature range from -50 °C to 100 °C.
What is the rated current and voltage?
The rated current (In) is 6.3A, and the rated voltage is 500V (AC/DC).
How is this terminal block mounted?
It is designed for mounting on a standard 35 mm DIN rail (top hat rail).
Troubleshooting
Fuse blows repeatedly
Verify that the connected circuit's current draw does not exceed the fuse rating (6.3A). Check for short circuits in the wiring or a faulty connected device.
Terminal block not secure on DIN rail
Ensure the DIN rail is standard 35mm and the terminal block is fully engaged. Check for obstructions or damage to the mounting clips.
Difficulty inserting or removing fuse
Ensure the correct fuse size (5x20mm or 5x25mm) is being used. Operate the swiveling holder smoothly; if it's stiff, check for debris or misalignment.
Conductor not securely held in screw terminal
Ensure the conductor's cross-sectional area is within the specified range (0.5-4mm²). Strip the correct length of insulation and tighten the screw firmly until the conductor is secure. Use cable end sleeves for fine-stranded conductors if needed.
Pros and Cons
Pros
- Quick and safe fuse replacement with a swiveling holder.
- Maintenance-free design reduces long-term service needs.
- Easy installation with secure screw connections.
- Suitable for a wide range of conductor sizes.
- Durable construction with good temperature resistance.
Cons
- Requires a separate closing plate for installation.
- Limited to 6.3A rated current, may not suit high-power applications.
- Single-level design limits complexity of wiring configurations.
- No integrated defect indication element.
Setup, Compatibility & Care
Setup:
- Ensure the 35 mm DIN rail is properly mounted.
- Slide the terminal block onto the DIN rail until it clicks into place.
- Connect conductors (solid-core, fine-strand, or multi-wired) ranging from 0.5 to 4mm² to the screw terminals.
- Insert the appropriate G-fuse (5 x 20 mm or 5 x 25 mm) into the swiveling holder.
- A closing plate is required to complete the terminal block assembly; install as needed.
Compatibility:
- Fuse Type: G-fuse 5 x 20 mm and 5 x 25 mm.
- Conductor Cross-Section: 0.5 mm² to 4 mm² (fine-strand with/without end sleeve, solid-core, multi-wired).
- Mounting: Standard 35 mm DIN rail.
- Voltage: Rated voltage of 500V (AC/DC).
Care:
- This terminal block is maintenance-free under normal operating conditions. No regular re-tightening of screws is required.
- Clean the exterior with a dry or slightly damp cloth if necessary. Avoid solvents or abrasive cleaners.
- Ensure fuses are correctly rated for the circuit to prevent overheating or damage.
