Wago 280-641 3-Conductor Terminal Block, 2.5mm², Grey

The Wago 280-641 is a professional-grade 3-conductor terminal block engineered for reliable and secure electrical connections in demanding environments. Designed with a 2.5mm² cross-section, this component provides a robust solution for wire termination within industrial and commercial control cabinets. Its compact grey housing is specifically optimized for efficient DIN-rail mounting, ensuring that electrical installations remain organized, safe, and highly conductive throughout their operational lifespan.

Advantages

This terminal block offers exceptional mechanical stability and electrical performance, making it a preferred choice for complex wiring systems. The 3-conductor design allows for streamlined distribution of electrical signals or power, significantly reducing the need for additional bridging components. Its high-quality construction ensures long-term resistance to vibration and thermal stress, which is essential for maintaining consistent connectivity in automation and control applications. The intuitive design facilitates quick installation and maintenance, helping to minimize downtime during system upgrades or repairs.

Suitable for

• Industrial automation control panels
• Commercial electrical distribution systems
• Building management and HVAC control cabinets
• General-purpose electrical installation projects

When it may not be suitable

This terminal block is not intended for use with conductors exceeding the specified 2.5mm² cross-section capacity. It is also not suitable for direct outdoor exposure without an appropriate protective enclosure to prevent moisture and dust ingress.

Key specifications

• Conductor capacity: 2.5mm²
• Connection type: 3-conductor
• Mounting style: DIN-rail
• Color: Grey
• Width: 5 mm
• Depth: 50.5 mm
• Height: 36.5 mm

How to use

To install the Wago 280-641, snap the terminal block onto a standard DIN-rail until it clicks securely into place. Strip the insulation from your electrical wires to the recommended length and insert them into the conductor entry points. Ensure the wires are fully seated to guarantee a reliable contact. If multiple blocks are used, they can be arranged side-by-side to create a clean and organized terminal strip for your specific wiring requirements.

What to consider before purchase

• Verify that the 2.5mm² cross-section matches your wire gauge requirements.
• Ensure your control cabinet has sufficient DIN-rail space for the 5 mm width per unit.
• Check the total number of connections needed to determine the quantity of blocks required.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring or maintenance tasks. Use appropriate wire stripping tools to avoid damaging the conductor strands, and verify that all connections are tight and secure before energizing the system.
