Product information

Description

The Wago 280-637 is a high-quality 3-conductor terminal block engineered for secure and reliable electrical connections in professional environments. Designed with a 2.5mm² cross-section, this component is specifically color-coded in yellow-green to serve as a protective earth grounding terminal. Its compact design allows for efficient space management within industrial and commercial control cabinets, ensuring that wiring remains organized and safe.

Advantages

This terminal block utilizes advanced spring pressure connection technology, which provides vibration-resistant and maintenance-free terminations. The 3-conductor configuration allows for easy branching of protective earth lines, simplifying complex wiring layouts. Its robust construction ensures long-term durability, while the standardized design facilitates quick and straightforward installation on DIN rails, significantly reducing assembly time in electrical panels.

Suitable for

Protective earth grounding in control cabinets
Industrial automation systems
Commercial electrical distribution panels
DIN rail mounting applications

When it may not be suitable

This terminal block is not intended for use with conductors exceeding the specified 2.5mm² cross-section capacity. It is also not suitable for applications requiring high-current power distribution beyond its rated electrical specifications or for environments where specialized hazardous area protection is mandatory without additional housing.

Key specifications

Conductor capacity: 2.5mm²
Connection type: 3-conductor
Color: Yellow-green
Width: 5 mm
Depth: 50.5 mm
Height: 36.5 mm
Mounting: DIN rail

How to use

To install the Wago 280-637, snap the terminal block onto a standard DIN rail until it clicks into place. Strip the insulation from your conductors to the recommended length and insert them into the spring-loaded clamping units. The spring mechanism automatically secures the wire, ensuring a gas-tight and reliable connection without the need for manual screw tightening. Ensure that all connections are fully seated before energizing the system.

What to consider before purchase

Verify that the conductor size matches the 2.5mm² specification
Ensure compatibility with your existing DIN rail system
Confirm the total number of connections required for your grounding circuit

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring modifications. Use appropriate wire stripping tools to prevent damage to the conductor strands, which ensures the integrity of the spring connection.
