The WAGO 2016-403 is a 3-way insulated jumper bar specifically engineered for the TOPJOB S terminal block system. This jumper bar facilitates efficient commoning of multiple terminal blocks, enabling streamlined wiring and reduced installation time. Constructed with pure electrolytic copper, the jumper contact ensures reliable current transfer up to the terminal block's rated capacity. The design incorporates a spring-loaded plug and socket principle, allowing for easy and secure connections. It's ideal for industrial automation, control panels, and building electrical systems where flexible and reliable power distribution is essential. Custom jumpers can be created by breaking and removing jumper contacts, offering further customization options.
