The RS PRO 157-3931 Insulated Crimp Bootlace Ferrule is a specialized terminal solution designed to provide a highly secure connection for multi-stranded wires. With a 12 mm pin length and 4.9 mm pin diameter, it is ideally matched for 8 AWG wire sizes, ensuring compatibility with various electrical installations.
Featuring an ivory-coloured nylon insulated collar, this bootlace ferrule is engineered for excellent electrical insulation, reducing leakage, creepage, and gas intrusion. The German colour coding facilitates instant size identification, enabling efficient wiring and minimizing installation errors.
The bootlace ferrule consists of a tin-plated copper tube, offering outstanding conductivity and corrosion resistance. Designed for use with screw terminals, terminal blocks, and captive terminals, the ferrule provides consistent crimping performance by capturing all wire strands within its flared funnel, preventing stray strands and possible short circuits.
Its reusable design allows repeated insertions and removals without degrading the wire end, making it ideal for maintenance, upgrades, and flexible wiring needs in consumer units, circuit breakers, control panels, and other electrical equipment requiring multi-stranded wire terminations.
Secure crimped termination, preventing wire strand fan-out and electrical short risks. Suitable for electrical panels, industrial control cabinets, circuit breakers, and consumer units. Excellent durability through nylon insulation and tin-plated copper construction.
Practical for repeat installations and maintenance scenarios.
The RS PRO 157-3931 bootlace ferrule finds application across industrial, commercial, and residential environments where reliable wire terminations are critical.
