Description
AT and AU are made of tinned electrolytic copper with flame-retardant PVC insulation, and the insulation colour per DIN 46237 corresponds to the ranges 0.5–1.5, 1.5–2.5 and 4–6 mm². The fork AU makes it possible to connect a wire without fully removing the terminal screw. The pin AP and flat APP are designed for European-type terminals and stranded conductors. The sockets AFH, the fully insulated AFH/A, the sockets with a branch AFH/M and the Faston-type plugs AFM, the round ACM and ACH and the sleeve AML have an internal metal bushing that increases vibration resistance. The ferrules are made from a copper capillary tube with a tinned surface. The insulated APF have a polyamide collar called Easy Enter, the twin APF/D take two wires into one terminal, and the uninsulated PF are made for 0.5–50 mm². They are crimped with manual ratchet pliers: SF-6J for insulated 0.5–6 mm², SF-6, SF-42, SF-55, SF-10W and SF-35W for ferrules of 0.5–35 mm², and the universal SF-C set has five sets of dies.
How to choose
First take the conductor cross-section, then the screw diameter or flat plug width of the terminal and the conductor type. The insulation colour per DIN 46237 immediately indicates the die slot of the pliers. For flexible stranded wire use the ferrules APF or PF, and for two wires in one terminal APF/D. Such wires, once terminated, are also accepted by the ADRI blocks for 6–35 mm².
