Product Information

Full details

This Phoenix Contact UK 6-FSI/C fuse terminal block is designed for industrial electrical installations, switchboards, and control panels requiring reliable circuit protection. Its key benefit is the integrated fuse holder for flat-type fuses, simplifying installation and maintenance. A potential consideration is its maximum load current of 30A, which may not be suitable for very high-power applications.

FAQs

What type of fuse does this terminal block use?

This terminal block is designed to accommodate standard flat-type fuses, often referred to as automotive-style blade fuses.

What is the maximum wire size this block can accept?

The UK 6-FSI/C model supports cable sections ranging from 26 AWG up to 8 AWG.

Can this terminal block be used in high-voltage applications?

No, the rated voltage is 250V. It is not suitable for applications exceeding this voltage level.

What is the maximum continuous current rating?

The terminal block has a maximum load current of 30A.

Is this terminal block suitable for outdoor use?

While constructed from durable polyamide (PA), its suitability for outdoor use depends on environmental factors like moisture, temperature extremes, and UV exposure. It is primarily designed for indoor industrial electrical installations.

How do I replace a blown fuse?

First, disconnect the main power supply to the circuit. Then, open the fuse holder mechanism on the terminal block, remove the old fuse, insert a new fuse of the correct rating, and close the holder. Finally, restore power.

What does the 'V0' rating signify?

The 'V0' rating according to UL94 standards indicates that the material is self-extinguishing and will not continue to burn once the flame source is removed, signifying a high level of fire safety.

Troubleshooting

Terminal block not securely mounting to DIN rail

Ensure the DIN rail is standard 35mm width and free of debris. Check if the block's mounting clip is damaged.

Fuse blows immediately upon power-up

The fuse rating may be too low for the load, or there is a short circuit in the connected wiring or device. Verify the circuit's current requirements and check for any direct wire-to-wire shorts.

Loose wire connection

Ensure the wire is properly stripped and inserted into the terminal. If using stranded wire, ensure it is securely terminated with an appropriate connector if needed. Tighten the terminal screw firmly but avoid over-tightening.

Overheating at the terminal connection

Check for a properly rated fuse. Ensure the wire gauge is appropriate for the current. Verify the connection is tight and clean. Overloading the circuit beyond 30A will cause excessive heat.

Pros and Cons

Pros

  • Provides integrated fuse protection, reducing component count.
  • Compact 8.2mm width saves valuable panel space.
  • Durable PA construction ensures longevity in demanding environments.
  • Easy mounting on standard 35mm DIN rails.
  • Suitable for a broad range of wire sizes (26-8 AWG).

Cons

  • Maximum rated voltage of 250V limits use in higher voltage applications.
  • Specific fuse type (flat-type) is required.
  • Not designed for applications exceeding 30A maximum load current.

Setup, Compatibility & Care

Setup:

  1. Mounting: The terminal block is designed for quick and secure mounting onto a standard 35mm DIN rail. Simply slide the block onto the rail and ensure it clicks into place.
  2. Wiring: Connect your wires to the two connection points. Ensure the wire size is within the supported range of 26 AWG to 8 AWG. Use appropriate crimp terminals or strip the wire to the correct length for secure insertion.
  3. Fuse Installation: Open the fuse holder mechanism and insert a compatible flat-type fuse. Ensure the fuse rating is appropriate for the circuit being protected and does not exceed the block's 30A maximum rating.

Compatibility:

  • DIN Rail: Compatible with standard 35mm width top-hat DIN rails.
  • Fuses: Requires specific flat-type automotive-style fuses.
  • Voltage: Rated for a maximum of 250V AC/DC.
  • Current: Maximum continuous load of 30A.

Care:

  • Cleaning: Disconnect power and remove the fuse before cleaning. Use a dry or slightly damp cloth to wipe down the exterior. Avoid using solvents or abrasive cleaners, as they can damage the polyamide material.
  • Inspection: Periodically inspect the terminal block for any signs of physical damage, loose connections, or corrosion. Check the fuse holder for cleanliness and ensure good contact with the fuse.
