Product Information
Full details
The Hager KN22E Terminal Block is designed for electricians and DIY enthusiasts requiring reliable and space-saving electrical connections for indoor installations. Its key benefit lies in tool-free solid wire insertion for up to 4 mm² conductors and clear color coding for easy identification, ensuring faster and more secure installations. A caveat to note is its suitability strictly for indoor environments. This terminal block features a robust design with a 63 A rated current, screw/spring-loaded connections, and a compact form factor.

FAQs
Can I use stranded wire with the KN22E terminal block?
The KN22E is designed for tool-free insertion of *solid* wires up to 4 mm². For stranded wires, you may need to use ferrules or a different connection method, depending on the specific requirements of your installation and local electrical codes.
What is the maximum current rating for this terminal block?
The Hager KN22E terminal block has a rated current of 63 A, making it suitable for significant electrical loads.
Is this terminal block suitable for outdoor use?
No, the KN22E is designed strictly for indoor use. Exposure to outdoor elements like moisture or extreme temperatures can compromise its performance and safety.
How do I connect a wire to the terminal block?
For solid wires up to 4 mm², strip the insulation and push the wire directly into the appropriate port until it is securely held by the internal spring mechanism. Ensure the connection is firm.
What does the color coding (Grey/Yellow) signify?
The grey and yellow colors are for easy identification. Typically, grey is used for line or neutral conductors, and yellow is used for grounding conductors, helping to prevent wiring errors.
What are the dimensions of the KN22E terminal block?
The dimensions are approximately 33 mm in height and 90 mm in width, designed for compact installations.
Does this terminal block require any special tools for installation?
For inserting solid wires up to 4 mm², no special tools are required beyond wire strippers. If screw terminals are used for specific connections, a screwdriver would be necessary.
Troubleshooting
Wire not securely held in terminal
Ensure a solid wire (not stranded) is used and inserted fully until it clicks or is firmly seated. Check if the wire gauge is within the 4 mm² limit. If using a screw terminal, ensure it is adequately tightened.
Terminal block feels loose
Verify that the terminal block is properly mounted within its intended enclosure or on a DIN rail. Ensure all securing screws or clips are fastened correctly.
Overheating during operation
Immediately disconnect power and inspect the connection. Ensure the wire gauge is appropriate for the 63 A rating and that all connections are tight. Check for any signs of damage or corrosion. Overloading the circuit can also cause overheating.
Pros and Cons
Pros
- Enables quick and easy installation of solid wires up to 4 mm² without tools.
- Compact dimensions maximize space in electrical enclosures.
- Color coding enhances visibility and reduces potential wiring mistakes.
- High current rating (63 A) supports significant electrical loads.
- Offers a secure connection through a combination of screw and spring mechanisms.
Cons
- Not suitable for use in outdoor or humid environments.
- Tool-free insertion is only applicable for solid wires; stranded wires may require different handling.
- Single-pole design limits its use in multi-phase applications without multiple units.
- Specific compatibility with other Hager components may be required for optimal performance.
Setup, Compatibility & Care
Setup:
- Ensure the power supply is completely disconnected before installation.
- Prepare the solid wire conductors up to 4 mm² by stripping the appropriate length of insulation (refer to specific electrical codes for exact lengths).
- Insert the solid wire directly into the designated port (grey for line/neutral, yellow for ground) until it is firmly seated. The spring-loaded mechanism will secure the wire.
- For connections requiring a screw terminal, use a compatible screwdriver to tighten the screw securely.
Compatibility:
- This terminal block is designed for use with solid conductors up to 4 mm².
- It is intended for indoor applications only.
- While designed for general use, compatibility with specific Hager systems or enclosures may be optimal.
Care:
- Keep the terminal block clean and free from dust and debris.
- Periodically inspect connections for tightness, especially after initial installation or if vibrations are present.
- Do not expose the terminal block to moisture or corrosive substances.
