Wago 2002-409 9-Way Jumper Bar for TOPJOB S Terminal Blocks 25A

The Wago 2002-409 9-way jumper bar is a high-quality electrical accessory engineered specifically for the TOPJOB S series of rail-mount terminal blocks. This component serves as an efficient solution for commoning potentials across multiple terminal blocks, streamlining the wiring process in complex electrical cabinets and control panels. With a robust construction and a rated current capacity of 25 A, it provides a stable and reliable electrical connection that meets rigorous industrial standards for safety and performance.

Advantages

The primary benefit of using this jumper bar is the significant reduction in installation time and labor costs. By allowing for quick bridging of up to nine terminal positions, it eliminates the need for individual wire jumpers, resulting in a cleaner and more organized wiring layout. The compact design ensures that it fits perfectly within the terminal block assembly without occupying excessive space, while the high-quality materials guarantee long-term durability and consistent electrical conductivity even in demanding environments.

Suitable for

• Industrial control panels and automation systems
• Power distribution cabinets
• Commercial electrical installations
• Modular terminal block assemblies requiring common potential distribution

When it may not be suitable

This jumper bar is specifically designed for the TOPJOB S terminal block series and is not compatible with other terminal block families or different mounting systems. It should not be used in applications where the current load exceeds the 25 A rating, as this could lead to overheating and potential failure of the connection.

Key specifications

• Number of positions: 9
• Rated current: 25 A
• Width: 45.2 mm
• Height: 19 mm
• Depth: 4.1 mm
• Compatibility: TOPJOB S terminal blocks

How to use

To install the jumper bar, align the contact pins with the designated slots on the top of the TOPJOB S terminal blocks. Press the jumper bar firmly into the slots until it clicks into place, ensuring a secure mechanical and electrical connection. The jumper can be shortened if fewer than nine positions are required by using the appropriate cutting tool, provided that the remaining sections are handled according to the manufacturer's safety guidelines.

What to consider before purchase

• Verify that your terminal blocks belong to the TOPJOB S series.
• Ensure the total current load of the circuit does not exceed 25 A.
• Check the physical space available in your enclosure to accommodate the 45.2 mm width of the jumper.

Usage recommendations

Always ensure that the power supply is disconnected before installing or modifying any electrical components. Regularly inspect the connection points for signs of wear or thermal stress to maintain optimal system performance.
