| Pole field | 02–24P; for KRZM, the corresponding frame size |
| Colour legend | 1 grey; 2 blue; 3 black; 4 green; 5 orange; 6 red; 7 transparent; 8 yellow; 9 white |
| General screw-head field | 0 slot; 1 cross |

The general legend covers the wider terminal range. Its 02–99 pole field does not extend these models beyond 2–24 poles, and screw fields do not add electrical contacts or wire clamps to KRZM. Illustrated products are green; the legend does not establish every colour and screw-option combination for every model.
P is the pole count, from 2 to 24. Dimensions are in millimetres.
