The 2002 TopJob rail-mounted terminal blocks from Wago have an additional jumper slot to provide flexibility in control cabinets, particularly for process measurement applications. The two-conductor, rail-mounted terminal blocks are for one output and two input applications in control cabinets for process measurement. The jumper slots also accommodate push-in type jumper bars and step-down jumpers All three jumper slots can serve as test plugs (2009-182) for 0.08 to 2.5mm2 (AWG 28-14) conductors, as well as test plug adapters for banana plugs (2009-174). Other terminal blocks in the 2002 range are available, namely carrier, through, ground conductor and ground blocks, disconnect and test blocks with or without mechanical interlocking, fuse terminal blocks for mini-automotive fuses, and one with or without a pivoting fuse holder.
