Product Information
Full details
The WAGO 870-501 terminal block is designed for electrical engineers and technicians seeking efficient and reliable wire termination in control cabinets and industrial automation. Its key benefit is providing a high-density, double-deck connection for multiple circuits within a compact footprint, a caveat being its specific wire size limitations. This 4-position, 2-level terminal block features a durable PA 6.6 insulator, front-entry wiring, and a secure clamp connection method, supporting up to 24A and 500V, making it suitable for a wide range of applications.

Extended Product Information
FAQs
What is the maximum wire size this terminal block can accept?
The WAGO 870-501 supports a maximum wire size of 4 mm² or 12 AWG.
What type of DIN rail is required for mounting?
This terminal block is designed for standard 35mm DIN rails.
Can this terminal block be used for power distribution?
Yes, with a rated current of 24A and a rated voltage of 500V, it is suitable for many control and low-power distribution applications within these limits.
How do I label the connections?
Each position on the terminal block features a side marking level where you can attach labels for circuit identification.
What is the material of the insulator?
The insulator is made from PA 6.6 (polyamide 6.6), which provides good electrical and mechanical properties.
What is the advantage of a double-deck terminal block?
Double-deck terminal blocks allow for twice the number of connections in the same horizontal space on a DIN rail compared to single-level blocks, significantly increasing wiring density and organization.
Does this terminal block require special tools for wiring?
Typically, standard wire stripping tools are sufficient. The clamp connection does not usually require specialized tools for secure engagement, but a screwdriver might be needed for some clamp types if applicable to the specific connection interface.
Troubleshooting
Wire connection is loose or failing.
Ensure the wire is stripped to the correct length and fully inserted into the clamp. Verify that the clamp mechanism is properly engaged. Check if the wire gauge is within the supported range (28-12 AWG).
Terminal block not securely mounted on DIN rail.
Confirm that the DIN rail is a standard 35mm profile. Ensure the terminal block is correctly clipped onto the rail and is not loose. Check for any obstructions or damage to the rail or the block's mounting mechanism.
Overheating at the connection point.
Verify that the conductor's cross-section is appropriate for the 24A rating. Check for proper wire insertion and clamp engagement. Ensure the total current load does not exceed the terminal block's rating.
Difficulty inserting wire.
Ensure the wire end is clean and not frayed. If using stranded wire, twist the strands tightly. Confirm the wire gauge is within the supported range. Do not force the wire; ensure the clamp mechanism is open.

Setup, Compatibility & Care
Setup:
- Ensure the terminal block is compatible with your wire sizes (28-12 AWG). Prepare wire ends by stripping insulation to the appropriate length.
- Mount the WAGO 870-501 onto a standard 35mm DIN rail. It can be clipped on securely.
- Insert the prepared conductor into the front-entry clamp connection. Ensure the wire is fully inserted and the clamp is firmly engaged.
- Use the side marking level to label each connection for clarity.
Compatibility:
- Primarily designed for 35mm DIN rail mounting.
- Compatible with solid and stranded conductors within the 28-12 AWG range (0.08mm² to 4mm²).
- Suitable for circuits rated up to 24A and 500V.
Care:
- Keep the terminal block clean and free from dust and debris.
- Periodically inspect connections for tightness and signs of wear, especially in high-vibration environments.
- Avoid exposing the terminal block to excessive moisture or corrosive substances.
- Cleaning can be done with a dry or slightly damp cloth. Ensure the block is de-energized before cleaning.
