Terminal block 3-contact Wago 221-613 for fine-stranded conductors 0.14–6 mm² (24–12 AWG)

Wago 221-613 is a 3-contact terminal block designed for fine-stranded conductors with cross-sections from 0.14 to 6 mm² (24–12 AWG). It provides three separate push-in connection points in a single compact housing, enabling secure, maintenance-free junctions without the need for tools. The terminal block accepts single and fine-stranded conductors within the specified range and is suitable for electrical installations, lighting circuits, control panels and field maintenance tasks where reliable, compact connections are required.

Advantages

The push-in connection system enables fast, tool-free wiring and reduces installation time while maintaining a reliable electrical contact. Transparent housing areas allow visual inspection of conductor insertion. The compact design saves space in junction boxes and control cabinets and supports multiple conductor types within the rated conductor cross-section. Durable materials ensure mechanical stability and long-term electrical performance under normal operating conditions.

Suitable for

• Electrical junctions in residential and commercial wiring
• Lighting circuits and fixture connections
• Control panels, terminal strips and distribution blocks
• Maintenance, repair and retrofit work where quick reconnections are needed

Key specifications

• Number of contacts: 3
• Conductor cross-section range: 0.14–6 mm² (24–12 AWG)
• Connection type: push-in (tool-free)
• Accepts single-core and fine-stranded conductors within stated range
• Compact single-piece housing for three connections
• Visual inspection window for conductor insertion

How to use

Strip the conductor insulation to the length recommended by the manufacturer, ensure the conductor strands are untwisted and straightened if necessary, then insert the conductor directly into the push-in port until it seats. Repeat for each of the three contacts. For multi-conductor connections, verify that the combined conductor types and cross-sections fall within the rated range. After insertion, perform a light pull test to confirm secure retention and, where applicable, perform continuity or voltage checks before restoring power.

Usage recommendations

Use the terminal block only with conductors within the specified 0.14–6 mm² range and ensure insulation stripping length matches manufacturer guidance. Avoid exceeding rated current and temperature limits for the installation environment; consult applicable wiring standards and local regulations for conductor grouping and derating when connecting multiple conductors in confined spaces.
