Wago 280-905 2-conductor terminal block 2.5mm2

The Wago 280-905 is a professional-grade 2-conductor terminal block engineered for secure and reliable electrical connections in demanding environments. Designed with a 2.5mm2 cross-section capacity, this terminal block is an essential component for organizing and connecting wiring within industrial control cabinets and distribution systems. Its robust construction ensures long-term stability, while the compact form factor allows for high-density wiring configurations on standard DIN rails, maximizing the available space in your electrical enclosures.

Advantages

This terminal block offers exceptional reliability through its advanced spring-pressure connection technology, which maintains consistent contact force regardless of vibrations or thermal expansion. The design facilitates quick and tool-free installation, significantly reducing assembly time during panel building. Its durable materials provide excellent insulation and mechanical strength, ensuring that your electrical circuits remain protected and operational under various load conditions.

Suitable for

• Industrial control cabinet wiring
• Distribution board installations
• Automation and process control systems
• General electrical infrastructure projects

This terminal block may not be suitable for applications requiring wire cross-sections larger than 2.5mm2 or for environments exposed to extreme chemical corrosion that exceeds the material specifications. It is also not intended for direct outdoor use without a protective, weather-resistant enclosure.

Key specifications

• Conductor capacity: 2.5mm2
• Connection type: 2-conductor
• Mounting: DIN-rail
• Width: 5 mm
• Depth: 53 mm
• Height: 28 mm

To use the Wago 280-905, snap the terminal block onto a compatible 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. The internal spring mechanism will automatically secure the wire, ensuring a gas-tight and vibration-resistant connection. To remove or adjust a wire, use a suitable operating tool to release the spring clamp.

What to consider before purchase

• Verify that your wire gauge is compatible with the 2.5mm2 capacity
• Ensure your DIN rail type matches the mounting requirements
• Calculate the total number of terminal blocks needed for your specific cabinet layout

For optimal performance and safety, always ensure that wires are stripped to the correct length and fully inserted into the terminal block. Regularly inspect connections in high-vibration environments to maintain system integrity.
