Product Information
Full details
This WAGO 770 Series 3-pole socket is designed for professional electrical installations requiring secure and stable connections for cables up to 4.00 mm². It offers integrated strain relief for enhanced cable protection and connection integrity, making it ideal for applications needing reliable power distribution. A potential consideration is its 'Other' IP degree of protection, which may require placement in environments where direct water or dust ingress is not a primary concern.

FAQs
What is the maximum cable size this socket can accommodate?
This socket is designed for both solid-core and fine-strand cables ranging from 0.5 mm² to 4.00 mm².
Does the socket come with a mating connector?
This product is a socket (female connector). A corresponding male connector (plug) is typically sold separately and is required for a complete connection.
What does the 'integrated strain relief' do?
The integrated strain relief clamps the cable jacket, preventing the wires inside from being pulled or stressed, which enhances connection reliability and safety.
What is the IP rating of this socket?
The IP rating is 'Other', often associated with IP20, meaning it is protected against solid objects larger than 12.5mm but offers no protection against liquids.
Can I use this socket for outdoor applications?
Due to its limited IP rating, it is not recommended for direct exposure to weather or moisture. It is best suited for indoor or protected industrial environments.
How many connections are available per pole?
There are two connections per pole, allowing for daisy-chaining or connecting multiple conductors to a single pole.
Is this connector halogen-free?
No, the housing material (Polyamide) is not halogen-free.
Troubleshooting
Connection is loose or intermittent
Ensure the conductor is fully inserted into the spring clamp. Check that the cable diameter is within the specified range for the strain relief. Verify the strain relief is properly secured.
Cable not holding securely
Verify the cable diameter is within the 7-11.5 mm range. Ensure the strain relief clamp is tightened correctly around the cable jacket.
Difficulty inserting conductor
Confirm the conductor type (solid or fine-strand) is compatible and within the 0.5-4 mm² range. Ensure the conductor end is clean and not deformed.
Pros and Cons
Pros
- Robust strain relief for secure cable mounting.
- Tool-free spring clamp connections for quick and reliable wiring.
- Suitable for a wide range of cable types (solid and fine-strand) up to 4 mm².
- Clear pole identification (L, N, PE) for safe and correct wiring.
- Compact dimensions allow for integration into tight spaces.
Cons
- IP20 rating indicates protection against solid objects larger than 12.5mm but no protection against water.
- Housing material (Polyamide) is not halogen-free.
- Locking mechanism is separate, requiring an additional step for full security.
- Maximum continuous temperature resistance for the contact part is 85°C.
Setup, Compatibility & Care
Setup:
- Ensure the power source is de-energized.
- Strip the solid-core or fine-strand cable to the appropriate length (refer to marking on connector if available).
- Insert the conductor into the spring clamp terminal until fully seated.
- Secure the cable using the integrated strain relief mechanism.
- For detachable use, ensure the mechanical coding aligns with the mating connector.
Compatibility:
- Designed for use with WAGO 770 series connectors.
- Accepts solid-core and fine-strand conductors ranging from 0.5 mm² to 4.00 mm².
- Compatible with cable diameters between 7 mm and 11.5 mm for the strain relief.
Care:
- Clean the exterior of the socket with a dry or slightly damp cloth.
- Avoid using solvents or abrasive cleaners.
- Periodically inspect connections for signs of damage or wear, especially in harsh environments.
