Wago’s (www.wago.us) X-COM S-Mini connectors are
only 3.5-mm wide. Other dimensions match those of X-COM S System (5.2 mm) and TopJob S terminal blocks, allowing interchangeability with a range of jumpers and marking strips. Although compact, the new connectors can terminate 16-awg conductors. The range includes one and two-conductor connectors with up to 15 poles, as well as one-conductor/one-pin and two-conductor/two-pin terminal blocks. Ground (earth) versions permit automatic contact to the carrier rail. Blocks are rated to 500 V at 13.5A.
