Wago 280-830 4-Conductor Terminal Block, Grey

The Wago 280-830 4-conductor terminal block is a professional-grade component engineered for secure and efficient electrical distribution. Designed for mounting on standard DIN-rails, this terminal block provides a reliable connection point for up to four conductors, making it an essential element for organized control cabinet wiring. Its compact design and robust construction ensure long-term stability in various industrial and commercial environments.

Advantages

This terminal block offers significant space savings due to its narrow 5 mm width, allowing for high-density wiring in confined spaces. The 4-conductor design simplifies complex circuit branching without the need for additional jumpers or external connectors. Its high-quality spring pressure connection technology ensures vibration-proof and maintenance-free electrical contacts, which are superior to traditional screw-type terminals in terms of reliability and installation speed.

Suitable for

• Industrial control cabinets
• Building automation systems
• Electrical distribution panels
• Machine control wiring
• Modular electrical installations

When it may not be suitable

This terminal block is not intended for use with conductors exceeding 2.5 mm² in cross-section. It is also not suitable for high-current power distribution applications that require larger gauge wiring or specialized high-voltage insulation beyond standard control circuit ratings.

Key specifications

• Conductor capacity: 4 conductors
• Nominal cross-section: 2.5 mm²
• Width: 5 mm
• Depth: 75 mm
• Height: 28 mm
• Mounting type: DIN-rail

How to use

To use the Wago 280-830, snap the terminal block onto a standard DIN-rail until it clicks into place. Strip the insulation from your conductors to the recommended length. Using a suitable operating tool, open the spring clamp, insert the conductor fully into the terminal point, and release the tool to secure the wire. Ensure that the conductor is firmly held and that no bare wire is exposed outside the terminal housing.

What to consider before purchase

• Verify that your conductor cross-section is compatible with the 2.5 mm² rating.
• Ensure sufficient space is available on your DIN-rail for the 5 mm width per unit.
• Check if the 4-conductor configuration meets your specific circuit branching requirements.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring work. Use only appropriate tools for operating the spring clamps to prevent damage to the terminal block or the conductor.
