In such cases, WAGO's touchproof, push-in type wire jumpers are the ideal solution. These jumpers are compatible with the following rail-mount terminal blocks: - 279 Series (1.5 mm²/16 AWG), - 280/775/780 Series (2.5 mm²/14 AWG) - 281/769/776/777/781 and 880 Series (4 mm²/12 AWG) They are available in three conductor lengths (60, 110 and 250 mm), allowing up to 60 terminal blocks to be commoned depending on their width (see table on the right). The 280/775/780 and 281/776/777/781 Series Terminal Blocks accept two wire jumpers, allowing the use of commoning chains. Furthermore, the 280/769/775/780/880 and 281/776/777/781 Series allow both wire jumper and adjacent jumper to be simul­ taneously plugged into a same terminal block.
