FAQs
What is the maximum voltage and current this terminal block can handle?
The UK 5-MTK-P/P has a rated voltage of 500V and a rated current of 16A.
What type of DIN rail is required for mounting?
This terminal block is designed for standard 35mm top-hat DIN rails (NS 35).
Can I use this block for fine-stranded conductors?
Yes, it accommodates fine-stranded conductors from 0.2mm² to 4mm² (with or without cable end sleeves).
How do I perform a test measurement using this block?
You can insert a standard 2mm test plug into the integrated test sockets after opening the knife disconnect to safely isolate the circuit section.
What is the width of this terminal block?
The width of the terminal block is 6.2mm.
Is this terminal block suitable for outdoor use?
While constructed from durable thermoplastic, it is primarily designed for control cabinet environments. Ensure appropriate environmental protection if used in harsh conditions.
Troubleshooting
Terminal block does not stay on DIN rail.
Ensure you are using a compatible 35mm top-hat DIN rail (NS 35). Check for any obstructions on the rail or the terminal block's mounting clip.
Connection is loose or intermittent.
Verify that the conductor is correctly stripped and inserted fully into the terminal. Tighten the screw terminal firmly but do not overtighten. Ensure the correct conductor size is used for the terminal capacity.
Knife disconnect is difficult to operate.
Check for any debris or foreign material obstructing the knife mechanism. Ensure conductors are neatly dressed and not interfering with the disconnect operation.
Pros and Cons

Setup, Compatibility & Care
Setup:
- Ensure the DIN rail is a standard 35mm top-hat type (NS 35).
- Slide the terminal block onto the rail until it locks securely.
- Connect conductors to the screw terminals, stripping insulation appropriately according to the conductor size.
- For disconnect operation, ensure the knife is in the closed position before connecting conductors.
Compatibility:
- Compatible with NS 35 mounting rails.
- Requires appropriate-sized conductors within the 0.2-6mm² range.
- Test sockets are designed for standard 2mm test plugs.
Care:
- Keep terminals clean and free from dust or debris.
- Periodically check screw connections for tightness, especially in vibration-prone environments.
- Use a damp cloth for cleaning; avoid abrasive cleaners or solvents.
