Double potential terminal block, 2202 Series, push-button This double potential terminal block (item number 2202-1441) simplifies electrical installations. Strip lengths must be between 10 and 12 mm when connecting conductors to this double potential terminal block. WAGO's double potential terminal blocks feature two independent potential current bars on one level to save space. Each side of the terminal block can be used to separately through-wire one potential. Featuring conductor terminals along with Push-in CAGE CLAMP®, this connector outperforms the competition. Our Push-in CAGE CLAMP® is a universal, maintenance-free connection solution for all conductor types, featuring a winning design: both solid and fine-stranded conductors with ferrules can be directly inserted without the need for tools or any preparation, such as crimping the ferrule. Depending on the type of conductor, this double potential terminal block is designed for conductor cross sections ranging from 0.25 mm² to 4 mm². This through rail-mount terminal block is operated with a push-button. Our TOPJOB® S rail-mount terminal blocks offer more than just secure electrical connections in various industrial applications and modern building installations. They also offer the perfect actuation option for every application: lever, push-button, or operating slot.
