Why Choose the WAGO 859-403 3-Way Jumper?
The WAGO 859-403 is a compact 3-way insulated jumper designed for electrically bridging compatible WAGO components via their jumper slots. It provides a simple and reliable method of distributing a common electrical potential across three adjacent connection points, reducing the need for additional wiring within control panels and automation assemblies.
Designed as a push-in jumper bar, the 859-403 can be inserted into compatible jumper slots to establish the required cross-connection quickly and neatly. Its three-position configuration makes it particularly useful where three adjacent compatible modules or terminals need to share the same potential, helping simplify panel wiring and maintain an organised installation.
The WAGO 859-403 has a rated current of 18 A and features a light grey insulated polyamide (PA66) housing. Measuring approximately 16 × 21.5 × 2.5 mm, the jumper provides a compact solution for professional electrical and automation applications while maintaining the space-efficient design expected from WAGO interface accessories.

Efficient Potential Distribution in Control Panels
Jumpers provide an efficient alternative to individually wiring adjacent connection points that require the same electrical potential. By inserting the WAGO 859-403 into compatible jumper slots, three adjacent positions can be electrically interconnected using a single compact accessory, reducing wiring effort and helping keep panel assemblies organised.
The insulated three-position construction is particularly useful in automation and control applications where multiple compatible relay, optocoupler or interface connections require common potential distribution. Its compact dimensions minimise additional space requirements while the push-in design supports quick installation during panel assembly, modification and maintenance.
Typical Applications
- Industrial control panels and electrical cabinets.
- Relay and optocoupler module assemblies.
- Automation and PLC control systems.
- Common-potential distribution across three compatible positions.
- Machine building and factory automation.
- Building automation control panels.
- Electrical panel assembly and modification.
- Replacement or expansion of existing WAGO interface assemblies.
