Product information

Description

The Wago 281-490 Jumper Bar is a professional-grade component engineered for seamless electrical distribution across terminal blocks. This 10-way comb-style jumper bar provides a reliable method for bridging adjacent terminals, ensuring that electrical circuits remain stable and secure within complex wiring systems. Designed for industrial and commercial applications, this insulated jumper bar facilitates efficient power distribution while maintaining high safety standards in electrical installations.

Advantages

The primary benefit of the Wago 281-490 is its ability to simplify wiring configurations by allowing multiple terminals to be connected simultaneously. Its insulated design enhances safety by preventing accidental contact with live parts, while the robust construction ensures long-term durability and consistent electrical conductivity. By reducing the need for individual wire jumpers, this component helps maintain a clean and organized control cabinet, which significantly improves maintenance efficiency and reduces the risk of connection errors.

Suitable for

Industrial control panels
Commercial electrical distribution systems
Modular terminal block assemblies
Power distribution circuits requiring common potential

When it may not be suitable

This jumper bar is specifically designed for compatible Wago terminal blocks. It may not be suitable for use with terminal blocks from other manufacturers or series that do not support this specific comb-style bridging system. It is also not intended for high-current applications exceeding the rated capacity of the terminal blocks themselves.

Key specifications

Type: Comb-style jumper bar
Capacity: 10-way
Insulation: Fully insulated
Width: 60 mm
Depth: 5 mm

How to use

To install the Wago 281-490, align the comb teeth with the designated jumper slots on the top of the terminal blocks. Press the jumper bar firmly into the slots until it clicks into place, ensuring a secure mechanical and electrical connection. Verify that the bar is fully seated across all ten terminals to guarantee uniform conductivity. No special tools are required for installation, though ensuring the terminal blocks are properly aligned on the DIN rail beforehand will facilitate a smoother assembly process.

What to consider before purchase

Compatibility with your specific terminal block series
Total number of terminals requiring a common connection
Space availability within the terminal strip assembly
Current rating requirements of the circuit

Usage recommendations

Always ensure that the power supply is disconnected before installing or modifying any electrical components. Verify that the jumper bar is fully inserted and that all connections are tight to prevent overheating or intermittent contact.
