Wago 283-677 3-Conductor Terminal Block 16mm2 Green and Yellow

The Wago 283-677 is a high-quality 3-conductor terminal block engineered for secure 16mm2 wire connections. Designed with a distinct green and yellow color scheme, this terminal block is specifically intended for protective earth grounding applications within industrial and electrical control cabinets. It utilizes advanced spring pressure connection technology to ensure reliable, vibration-proof performance, making it a dependable choice for demanding electrical infrastructure.

Advantages

This terminal block offers exceptional mechanical stability and electrical safety through its robust design. The spring-loaded connection mechanism eliminates the need for manual screw tightening, which significantly reduces maintenance time and prevents loose connections caused by thermal expansion or vibrations. Its compact footprint allows for efficient space utilization on standard DIN-rails, while the clear color coding ensures quick identification of grounding points during installation and troubleshooting.

Suitable for

• Protective earth grounding in industrial control panels
• Electrical distribution systems requiring vibration-resistant connections
• Professional wiring installations on DIN-rail systems
• Applications involving 16mm2 cross-section conductors

This terminal block may not be suitable for applications requiring wire sizes outside the specified 16mm2 capacity or for environments where specialized hazardous-area certifications not covered by this model are mandatory. It is also not intended for direct connection to non-grounding power circuits due to its specific color-coded design.

Key specifications

• Conductor capacity: 16mm2
• Connection type: 3-conductor
• Mounting style: DIN-rail
• Width: 12 mm
• Depth: 104.5 mm
• Height: 37.5 mm
• Color: Green and Yellow

How to use

To use the Wago 283-677, mount the terminal block onto a standard DIN-rail until it clicks securely into place. Strip the insulation from your 16mm2 conductor to the recommended length. Open the clamping unit using a compatible operating tool, insert the conductor fully into the terminal, and release the tool to secure the wire. Ensure the connection is firm by gently pulling on the wire.

What to consider before purchase

• Verify that your conductor cross-section is exactly 16mm2
• Ensure your mounting rail is compatible with standard DIN-rail dimensions
• Check if the 3-conductor configuration meets your specific wiring topology

Usage recommendations: Always ensure that the power is disconnected before performing any wiring work. Use only calibrated tools for stripping and operating the terminal clamps to maintain the integrity of the connection.
