ABB F2040 Ferrule insulated copper 4mm² grey STA-KON

STA-KON® insulated ferrule made of high-conductivity copper. 0.114 inch small diameter, 0.189 inch large diameter, 1.024 inch overall length, 0.708 inch barrel length. T3 and ERG4 crimping tool. Ferrules ensure reliable electrical connections when terminating conductors in screw clamp terminal blocks. Fraying and breaking of wire strands is prevented and the possibility of an unreliable connection is minimized. Insulated ferrules prevent conductor breakage due to bending, wire stress or vibration, while facilitating wire insertions into the terminal block clamp. Ferrules are the preferred alternative to twisting wire stands or tinning the wire end before terminating into a terminal block. Ferrules are thin-walled copper tubes, which are mechanically crimped onto the ends of stranded wires. They are easy to use - simply strip the wire, slide the ferrule onto the end of the wire and crimp. Meets emerging global standards, requiring wire-to-metric style terminal block installations to be terminated with a pin style terminal.
