• Modular control panel assembly

This terminal block may not be suitable for applications requiring wire cross-sections significantly larger than 2.5 mm². It is also not intended for use in environments exposed to extreme moisture or corrosive substances without appropriate protective enclosures.

Key specifications

• Cross-section: 2.5 mm²
• Levels: Three-level design
• Width: 5 mm
• Depth: 103 mm
• Height: 76.5 mm

To install the Wago 280-547, mount the terminal block onto a standard DIN rail within your enclosure. Strip the insulation from your conductors to the recommended length and insert them into the terminal points. Ensure that each connection is fully seated to maintain a secure electrical contact. The multi-level design allows for systematic grouping of circuits, which simplifies the overall wiring architecture of the cabinet.

What to consider before purchase

• Verify that the 2.5 mm² cross-section is compatible with your specific wire gauges.
• Ensure the 5 mm width fits within your existing terminal rail layout.
• Confirm that the three-level configuration meets your circuit density requirements.

For optimal performance, always ensure that all connections are tightened to the manufacturer's specified torque and that the terminal block is installed in a clean, dry environment to prevent oxidation or short circuits.
