When it may not be suitable

This terminal block is not intended for high-current power distribution applications exceeding its rated capacity. It is also not suitable for environments requiring specialized protection against extreme moisture or corrosive chemical exposure without an appropriate protective enclosure.

Key specifications

• Conductor cross-section: 2.5mm²
• Number of levels: 3
• Width: 5 mm
• Depth: 103 mm
• Height: 76.5 mm
• Color: Grey

How to use

To use the Wago 280-549, mount the terminal block onto a standard DIN rail within your control cabinet. Strip the insulation from your conductors to the recommended length and insert them into the spring-clamp terminals. Ensure the wire is fully seated to guarantee a secure, gas-tight connection. The multi-level design allows for the systematic grouping of signals or power lines, enabling organized and efficient wiring management.

What to consider before purchase

• Verify that the 2.5mm² conductor size matches your specific wiring requirements.
• Ensure the 5mm width fits within your existing DIN rail configuration.
• Confirm that the 3-level design aligns with your circuit density needs.

Usage recommendations

For optimal performance and safety, always ensure that the terminal block is installed by a qualified professional in accordance with local electrical regulations and that all connections are inspected for proper seating before energizing the system.
