Basis: WAGO 221 series data sheet and the 221-412 data sheet; widths of 413 / 415 from the unlabelled series table (first column); McMaster-Carr linked for CAD
Catalog version: 2026-10-20

Sizes: see table below
- The 221 series is WAGO's compact lever-operated splicing connector (the one electricians call a 'lever nut'). 221-412 is two conductors, 221-413 three, 221-415 five. Rated 450 V / 4 kV / 2 and 32 A on the data sheet; 100 % transparent housing with test slots; strip length 11 mm (0.43 in); weight 1.6 g (221-412).
- Conductors: solid and stranded 0.2 to 4 mm² (24 to 12 AWG); fine-stranded 0.14 to 4 mm².
- Dimensions: the 221-412 data sheet labels width 13.1 mm, height 8.3 mm and depth 18.6 mm. The series sheet lists 13.1 / 8.3 / 18.6 (412), 18.7 / 8.3 / 18.6 (413) and 29.9 / 8.3 / 18.6 (415) in three unlabelled columns; the first column grows with the conductor count and equals the 412's labelled width, so it is read as the width. The lever, test slots and conductor entries are not drawn in the numbers.
- Left out: the 221-2411 / -2413 / -2415 (inline splicing) and 221-612 / 613 / 615 (with inline), the 222 series, and enclosure/mounting accessories. Anderson Powerpole housings were not tabulated: the manufacturer's drawing labels were not readable in the copies reached (the Anderson page itself lists 20 to 10 AWG wire and up to 45 A, no dimensions). No files: a block with levers is not defined by the three numbers.
