Quickly and easily connect all types of conductors of different cross-sections using two-, three- and five-wire terminal blocks. The new connectors feature fine-coil conductors from 0.14 to 4 mm², as well as solid and conductive strands from 0.2 to 4 mm² (24–12 AWG). With the 6 mm² (10 AWG) variant, you can connect all types of conductors – with cross sections from 0.5 to 6 mm² (2−10 AWG).


With the new 221 series connectors, you can now test the voltage from both sides – even when they are installed.

Whether it's a DIN-35 rail or a DIN-15 rail with the right adapter, the 221 series staple connectors can easily snap or screw onto both types of rail
