Wago 280-833 4-Conductor Terminal Block, 2.5 mm², Grey

The Wago 280-833 is a professional-grade 4-conductor terminal block engineered for secure and efficient electrical distribution. Designed for a rated cross-section of 2.5 mm², this component provides a robust connection point for complex wiring systems, ensuring long-term stability and reliability in demanding environments. Its compact grey housing allows for organized circuit management within control cabinets and automation panels.

Advantages

This terminal block utilizes advanced clamping technology to ensure vibration-resistant connections that maintain integrity over time. The 4-conductor design facilitates easy branching of circuits, reducing the need for additional jumpers or complex wiring configurations. Its compact dimensions allow for high-density mounting on standard DIN rails, maximizing space efficiency in electrical enclosures while maintaining clear accessibility for maintenance and testing.

Suitable for

• Industrial control cabinets
• Automation and process control systems
• Building management and electrical distribution panels
• Complex circuit branching and signal distribution

When it may not be suitable

This terminal block is not intended for use with conductors exceeding the specified 2.5 mm² cross-section or for applications requiring high-current power distribution beyond its rated capacity. It is also not suitable for direct outdoor exposure without a protective, weather-rated enclosure.

Key specifications

• Conductor capacity: 2.5 mm²
• Connection type: 4-conductor
• Width: 5 mm
• Depth: 75 mm
• Height: 28 mm
• Color: Grey

How to use

To use the Wago 280-833, mount the terminal block onto a compatible DIN rail until it clicks into place. Strip the insulation from your wires to the recommended length and insert them into the clamping units. Ensure the wire is fully seated to establish a secure electrical contact. The design allows for quick installation and removal, making it efficient for both initial assembly and subsequent system modifications.

What to consider before purchase

• Verify that the conductor size matches the 2.5 mm² specification.
• Ensure the DIN rail type in your enclosure is compatible with the mounting mechanism.
• Calculate the total number of connections required to determine the necessary quantity of blocks.

Usage recommendations

For optimal performance and safety, always ensure that wires are stripped to the correct length and that the terminal block is securely locked onto the DIN rail before applying power to the circuit.
