Wago 280-834 4-Conductor Terminal Block, 2.5mm², Blue

The Wago 280-834 is a high-quality 4-conductor terminal block engineered for secure and efficient electrical wiring. Designed to accommodate a 2.5mm² cross-section, this component provides a reliable connection point for various electrical circuits. Its compact blue housing is specifically optimized for DIN-rail mounting, making it an essential element for organized and space-saving electrical installations in industrial environments and control cabinets.

Advantages

This terminal block offers superior reliability through its advanced spring pressure connection technology, which ensures that wires remain securely fastened even under conditions of vibration or thermal expansion. The 4-conductor design allows for efficient distribution of electrical signals or power, reducing the need for additional bridging components. Its standardized dimensions facilitate easy integration into existing DIN-rail systems, while the blue color coding helps in identifying neutral conductors within complex wiring setups, thereby improving maintenance efficiency and safety.

Suitable for

• Industrial control cabinet wiring
• Automation and process control systems
• Distribution boards and junction boxes
• General electrical installations requiring secure wire termination

When it may not be suitable

This terminal block is not intended for use with wire sizes exceeding its 2.5mm² capacity or for applications requiring high-current power distribution beyond its rated specifications. It is also not suitable for direct outdoor exposure without a protective enclosure.

Key specifications

• Conductor capacity: 2.5mm²
• Number of connection points: 4
• Mounting type: DIN-rail
• Width: 5 mm
• Depth: 75 mm
• Height: 28 mm
• Color: Blue

How to use

To use the Wago 280-834, first ensure that the DIN-rail is securely installed in your cabinet. Snap the terminal block onto the rail until it clicks into place. Strip the insulation from your wires to the recommended length and insert them into the spring-loaded connection points. The internal mechanism will automatically clamp the wire, ensuring a gas-tight and vibration-resistant connection without the need for specialized tools.

What to consider before purchase

• Verify that your wire gauge is compatible with the 2.5mm² specification.
• Ensure that the DIN-rail type in your cabinet matches the mounting requirements.
• Check if the blue color coding aligns with your specific wiring standards for neutral or signal identification.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring tasks. Regularly inspect connections in high-vibration environments to maintain system integrity.
