Product information

Description

The Wago 781-631 is a professional-grade 3-conductor through terminal block designed for reliable electrical distribution in industrial environments. Engineered for mounting on standard DIN-rails, this component provides a secure and organized connection point for wiring within control cabinets and electrical distribution boards. Its robust construction and precise engineering ensure long-term stability for various electrical systems.

Advantages

This terminal block offers significant benefits for electrical installers, primarily through its space-saving design that allows for high-density wiring in confined spaces. The 3-conductor configuration simplifies complex circuit branching, reducing the need for additional jumpers or external connection points. With a high rated voltage capacity, it provides versatility for demanding electrical applications while maintaining consistent contact quality and vibration resistance.

Suitable for

Industrial control cabinet wiring
Electrical distribution systems
Automation and process control panels
Building installation technology

When it may not be suitable

This terminal block is not intended for use in environments with extreme moisture or corrosive gases unless housed in an appropriate protective enclosure. It is also not suitable for conductors exceeding the specified 4mm² cross-section capacity.

Key specifications

Conductor capacity: 4mm²
Number of connection points: 3
Rated voltage: 1000V
Width: 6mm
Depth: 77mm
Height: 43.5mm
Mounting type: DIN-rail

How to use

To use the Wago 781-631, snap the terminal block onto a standard DIN-rail until it clicks securely into place. Strip the insulation from your conductors according to the manufacturer's recommended length. Insert the prepared wire into the terminal opening until it is firmly seated. Ensure that the connection is tight and that no bare wire is exposed outside the terminal housing. For multi-conductor configurations, repeat the process for each connection point.

What to consider before purchase

Ensure the DIN-rail type matches the mounting requirements
Verify that the conductor cross-section is compatible with the 4mm² rating
Check the total space available in the enclosure for the 6mm width per block
Confirm the voltage requirements of your circuit do not exceed 1000V

Usage recommendations

Always verify that the power supply is disconnected before performing any wiring tasks. Ensure that all connections are inspected for mechanical integrity before energizing the system.
