Wago 280-837 4-Conductor Terminal Block, 2.5 mm², Multicolour

The Wago 280-837 is a professional-grade 4-conductor terminal block engineered for secure and reliable electrical connections in demanding environments. Designed to accommodate wires with a cross-section of 2.5 mm², this component serves as a fundamental building block for organized electrical distribution within control cabinets and industrial automation systems. Its robust construction ensures long-term mechanical and electrical stability, facilitating efficient wiring management and maintenance.

Advantages

This terminal block offers exceptional reliability through its advanced spring-pressure connection technology, which maintains constant contact force regardless of thermal expansion or vibration. The 4-conductor design allows for versatile branching and distribution of electrical signals or power within a compact footprint. Its durable materials provide high resistance to environmental stressors, ensuring consistent performance in both commercial and industrial settings while simplifying the installation process for technicians.

Suitable for

• Industrial control cabinet wiring
• Electrical distribution systems
• Automation and control panel assembly
• Branching of electrical circuits

This terminal block may not be suitable for applications involving wire cross-sections significantly larger or smaller than the specified 2.5 mm² capacity. It is also not intended for direct exposure to extreme outdoor weather conditions or high-moisture environments without appropriate protective housing.

Key specifications

• Conductor capacity: 2.5 mm²
• Number of connection points: 4
• Width: 5 mm
• Depth: 75 mm
• Height: 28 mm

To use the Wago 280-837, strip the insulation from your conductors according to the manufacturer's recommended length. Insert the wire into the terminal opening until it is fully seated. The spring-loaded mechanism automatically secures the conductor, ensuring a gas-tight connection without the need for specialized tools or manual tightening. To remove or adjust a wire, use a standard screwdriver to actuate the spring release.

What to consider before purchase

• Verify that your wire gauge is compatible with the 2.5 mm² specification.
• Ensure the mounting rail type in your cabinet is compatible with the terminal block dimensions.
• Confirm the total number of connections required for your specific circuit layout.

Always ensure that the power supply is disconnected before performing any wiring operations to prevent electrical hazards and ensure safe installation practices.
