966903-2

Wire ferrules are a necessary accessory for terminations, mainly used to terminate stranded copper wires. Fitting a ferrule to your wire connection adds extra protection against pulled or bent wires. 966903-2 ferrules are crimp types, manufactured for superior tensile strength. This article will cover the uses, working principle, crimp process and restrictions of 966903-2 ferrules.

Application Field

The 966903-2 ferrule from Schneider Electric is designed for efficient termination of 20 to 10 AWG stranded wires. These ferrules are suited for use in demanding applications such as industrial, lighting, automation, machines, and equipment in physically demanding conditions. The 966903-2 is perfect for use in extreme climates and wet/humid environments, as it resists corrosion and provides an airtight seal.

Working Principle

966903-2 ferrules are designed to work with standard and crimp-style lug terminals, providing secure connections between the wire and the terminal. The process of attaching the ferrule involves the crimping of the ferrule onto the stranded wire. The crimp process ensures maximum electrical contact between the wire and ferrule, leading to stable connections that can be relied upon for a long-term service. The internal insulation material of the ferrule provides waterproofing and optimal strain relief.

Crimp Process

To ensure proper connection between the ferrule and the stranded wire, the crimping process should be done carefully and accurately. The crimp tool should be the correct size and shape for the ferrule, and the pressure applied to the crimp should be enough to completely seat the ferrule. Once the crimping process is complete, it is advisable to verify the crimp and connection.

Restrictions

966903-2 ferrules are designed for use in electrical applications and must not be used for non-electrical applications. Also, these ferrules must never be reused, as this will lead to unreliable connections and potential damage. Further, due to their common use in industrial applications, 966903-2 ferrules are not acceptable for applications that require UL, VDE, or CSA approval.

Conclusion

966903-2 wire ferrules are developed for use in critical electrical applications. They provide reliable connections with superior tensile strength and withstand harsh conditions. The crimp process used to connect the ferrule to the wire ensures maximum connection and optimal strain relief. Despite offering superior performance, 966903-2 ferrules do not meet standards for applications requiring UL, VDE, or CSA approval.
