The WAGO 249-126 push-in wire jumper offers a convenient and safe method for establishing connections between terminal blocks, particularly when they are not adjacent on a rail. Designed with an insulated construction and a 110mm wire length, it's compatible with several WAGO terminal block series including 279, 280/775/780, 281/769/776/777/781, and 880. The jumper allows for commoning chains and accommodates multiple jumpers per terminal block in certain series, enhancing flexibility in machine and control system installations. It's an ideal solution for creating additional connections and simplifying wiring processes.
