Why Choose the WAGO 859-404 4-Way Jumper?

The WAGO 859-404 is a compact 4-way insulated jumper designed for electrically bridging compatible WAGO components via their jumper slots. Part of the WAGO 859 Series, it provides a simple and efficient method of distributing a common electrical potential across four adjacent connection points without installing separate interconnection wires.

Designed as a push-in type jumper bar, the 859-404 can be inserted directly into compatible jumper slots for fast and organised cross-connection. Its four-position configuration is particularly useful in relay, optocoupler and interface assemblies where multiple adjacent modules require a shared electrical potential, helping reduce wiring time and maintain a tidy control panel layout.

The WAGO 859-404 has a rated current of 18 A and features an insulated light grey construction. Measuring approximately 22 × 21.5 × 2.5 mm, it provides a compact potential-distribution solution for professional industrial control and automation applications while occupying minimal additional space within the electrical assembly.

Efficient Potential Distribution in Control Panels

Jumpers provide a space-efficient alternative to individually wiring adjacent connection points that require a common electrical potential. By inserting the WAGO 859-404 into compatible jumper slots, four positions can be electrically interconnected using one compact accessory, helping reduce conductor preparation, wiring effort and the number of individual connections required within the panel.

The insulated four-position construction is particularly useful in automation and control applications where compatible relay, optocoupler or interface modules require common potential distribution. Its push-in installation and compact dimensions support efficient panel assembly while helping maintain a clean and organised wiring layout during initial construction, system expansion and maintenance.

Typical Applications

• Industrial control panels and electrical cabinets.
• Relay and optocoupler module assemblies.
• Automation and PLC control systems.
• Common-potential distribution across four compatible positions.
• Machine building and factory automation systems.
• Building automation control panels.
• Electrical panel assembly and modification.
• Expansion and maintenance of compatible WAGO interface assemblies.
