Wago 280-671 3-Conductor Terminal Block 2.5mm²

The Wago 280-671 is a high-quality 3-conductor terminal block engineered for secure and efficient electrical connections. Designed with a 2.5mm² cross-section, this component is a staple for professional electrical installations, offering a reliable interface for wiring in industrial and commercial environments. Its compact architecture allows for optimal space management within control cabinets, ensuring that complex wiring systems remain organized and accessible.

Advantages

This terminal block utilizes advanced spring pressure connection technology, which provides a vibration-proof and maintenance-free connection. By eliminating the need for frequent retightening, it significantly reduces long-term maintenance costs and improves system uptime. The robust construction ensures durability under demanding conditions, while the 3-conductor design facilitates versatile circuit branching and distribution directly on the DIN rail.

Suitable for

• Industrial control cabinet wiring
• Commercial electrical distribution systems
• Automation and instrumentation projects
• General electrical panel assembly

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 designed for high-current power distribution applications that require larger wire gauges or specialized high-voltage insulation beyond standard industrial ratings.

Key specifications

• Conductor capacity: 2.5mm²
• Number of connection points: 3
• Width: 5 mm
• Depth: 64 mm
• Height: 28 mm
• Mounting type: DIN rail

How to use

To use the Wago 280-671, mount the unit onto a standard DIN rail until it clicks into place. Strip the insulation from your electrical wires to the recommended length. Using a suitable screwdriver, actuate the spring mechanism to open the clamping point, insert the conductor fully into the terminal, and release the screwdriver to secure the wire. Ensure that the connection is firm and that no bare copper is exposed outside the terminal housing.

What to consider before purchase

• Verify that your wire gauge is compatible with the 2.5mm² specification.
• Ensure you have sufficient DIN rail space for the 5mm width per unit.
• Confirm the total number of connections required for your circuit design.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring work. Use appropriate wire stripping tools to prevent damage to the conductor strands, which ensures the integrity of the spring pressure connection.
