Product information

Description

The Wago 281-657 is a high-quality 4-conductor protective earth terminal block engineered for secure and reliable grounding in electrical installations. Designed for mounting on standard DIN-rails, this terminal block features a distinct green and yellow housing that allows for immediate identification as a protective earth connection. It utilizes the proven CAGE CLAMP connection technology, ensuring vibration-proof and maintenance-free electrical contacts for conductors up to 4 mm². This component is an essential element for organizing complex wiring systems in industrial control cabinets and distribution panels.

Advantages

This terminal block offers significant benefits for professional electrical assembly, primarily through its robust CAGE CLAMP technology which simplifies the wiring process while maintaining high contact pressure. The 4-conductor design allows for efficient distribution of ground connections within a compact footprint, saving valuable space on the DIN-rail. Its standardized design ensures compatibility with common mounting systems, and the clear color coding minimizes the risk of wiring errors during installation or maintenance, contributing to overall system safety and reliability.

Suitable for

  • Grounding applications in industrial control cabinets
  • Distribution panels requiring secure protective earth connections
  • Electrical systems where vibration-proof connections are essential
  • Projects utilizing 35 x 15 or 35 x 7.5 DIN-rails

When it may not be suitable

This terminal block is specifically designed for protective earth (grounding) purposes and should not be used for carrying live phase or neutral currents. It is not intended for applications requiring wire gauges larger than 4 mm² or for environments that exceed the specified mechanical and electrical tolerances of the CAGE CLAMP system.

Key specifications

  • Connection type: CAGE CLAMP
  • Conductor capacity: 4 mm²
  • Number of connection points: 4
  • Mounting: DIN-rail 35 x 15 and 35 x 7.5
  • Width: 6 mm
  • Depth: 86 mm
  • Height: 29 mm
  • Color: Green/Yellow

How to use

To install the Wago 281-657, snap the terminal block onto the appropriate DIN-rail until it clicks securely into place. Strip the insulation from your conductor to the recommended length and insert it into the CAGE CLAMP opening using a suitable operating tool. Ensure the wire is fully inserted to achieve a reliable contact. The terminal block provides four connection points, allowing for the commoning of multiple ground wires to a single protective earth rail.

What to consider before purchase

  • Ensure the DIN-rail type matches the 35 mm standard
  • Verify that the conductor cross-section does not exceed 4 mm²
  • Check if the 4-conductor configuration meets your specific grounding requirements
  • Confirm that the physical dimensions fit within your existing cabinet layout

Usage recommendations

Always ensure that the DIN-rail itself is properly grounded to the main protective earth bus of the installation to maintain the integrity of the grounding system. Use only calibrated tools for wire stripping and insertion to prevent damage to the conductors or the terminal block mechanism.
