Product Information
Full details
The Lapp H05V2-K 90° installation wire is designed for electrical installations requiring a flexible, high-temperature rated cable. It is ideal for electricians and DIY enthusiasts working on control cabinets, switchgear, and other internal wiring applications where ease of handling and durability are paramount. A key benefit is its 90°C rated insulation, allowing for higher current carrying capacity in confined spaces. However, users should be aware that its CPR Euro fire class rating is 'eca', indicating a basic level of fire performance.

FAQs
What does 'H05V2-K' mean?
'H05' indicates a 500V/300V rated flexible cord. 'V2' signifies a PVC insulation rated for 90°C. 'K' denotes a flexible conductor (Class 5).
Can this wire be used for mains power supply (e.g., 230V)?
Yes, with a nominal voltage of 500V, it is suitable for internal wiring applications, including those connected to standard mains voltages, provided the current and installation conditions are within its specifications.
What is the conductor made of?
The conductor is made of copper and is classified as Class 5, meaning it is highly flexible.
Is this wire suitable for outdoor use?
No, this wire has PVC insulation and is rated 'eca' for fire performance. It is intended for indoor electrical installations and is not designed to withstand outdoor environmental factors like UV radiation or moisture.
What is the CPR Euro fire class 'eca'?
CPR Euro fire class 'eca' is a basic classification under EN 13501-6. It indicates a minimal contribution to fire spread and is suitable for general building applications where stringent fire performance is not the primary requirement.
Can I use this wire if my application requires a higher temperature rating than 90°C?
No, operating the wire above its rated 90°C will degrade the insulation and pose a safety risk. You would need a cable specifically rated for higher temperatures.
Where can I find other colors or sizes of Lapp installation wire?
Lapp offers a range of installation wires in different colors and cross-sectional areas. Please refer to Lapp's product catalog or contact their support for sibling products like the H05V-K series or other H05V2-K variants.
Troubleshooting
Wire is difficult to bend or route.
Ensure you are using the correct wire type (H05V2-K is designed for flexibility). Check for kinks or damage sustained during transport or handling. If routing is extremely tight, consider a smaller diameter wire if application permits.
Connection feels loose.
Re-crimp or re-insert the wire into the terminal. Ensure the terminal is properly sized for a 1mm² conductor and is fully tightened. Check that the conductor strands are making good contact.
Wire insulation appears damaged.
Immediately disconnect power. Inspect the damaged area. If the insulation is compromised, the wire must be replaced to prevent short circuits or electrical hazards.
Overheating during operation.
Verify the current load does not exceed the wire's capacity for its operating temperature. Ensure proper ventilation in the enclosure. Check that all connections are tight, as poor connections can cause excessive heat.
Pros and Cons
Pros
- High flexibility for easier installation.
- 90°C temperature rating allows for higher current capacity.
- Durable PVC insulation provides good protection.
- Standard 1mm² cross-section for common applications.
- Clear yellow color coding for identification.
Cons
- CPR Euro fire class 'eca' is a basic fire performance rating.
- Not suitable for outdoor or wet environments due to PVC insulation.
- Limited voltage rating of 500V may restrict use in some high-voltage applications.
- Only available in this specific configuration, other colors/sizes sold separately.
Setup, Compatibility & Care Instructions
Setup:
- Stripping Insulation: Use a wire stripper suitable for 1mm² conductors to carefully remove the PVC insulation, taking care not to nick the copper strands. The outer diameter is approximately 2.8mm.
- Termination: Crimp appropriate terminals onto the stripped conductor ends or insert directly into compatible terminal blocks. Ensure a secure connection.
- Routing: Route the wire neatly, avoiding sharp bends or kinks that could damage the flexible conductors. Use cable ties or conduits as needed for organization and protection.
Compatibility:
- Voltage: Suitable for nominal voltages up to 500V.
- Temperature: Designed for operating temperatures up to 90°C.
- Environment: Primarily intended for dry, internal electrical installations. Not recommended for exposed outdoor use or environments with high moisture.
- Standards: Complies with CPR Euro fire class 'eca'.
Care:
- Cleaning: If cleaning is necessary, disconnect power and use a dry or slightly damp cloth. Avoid harsh solvents or abrasive materials that could damage the insulation.
- Inspection: Periodically inspect the wire for any signs of physical damage, fraying, or insulation degradation, especially in high-vibration or high-temperature environments.
