Overview

The NSI Industries C-4 is a high-conductivity tinned copper compression splice designed for reliable electrical connections. Engineered from premium copper tubing, this long barrel splice offers superior conductivity and durability. Its tin plating provides excellent corrosion resistance, ensuring longevity in various industrial environments. The C-4 is specifically designed for 4 AWG copper conductors and is compatible with a wire range of 4 AWG to 6 AWG, with an expanded range available when used with the NSI N12ID dieless compression tool. This connector is UL486A Listed and suitable for use at voltages up to 35KV when properly installed according to cable manufacturer's voltage stress relief instructions. For bare splices, the maximum voltage rating is 5KV. The C-4 features serrations that clearly indicate proper crimp locations, facilitating accurate and secure installations. It is also marked with a die index and color-coded (Gray for 4 AWG) for easy identification and reference, streamlining inventory management and field application. With a temperature rating of 90°C and a maximum voltage rating of 600V (UL Listed), the C-4 is a versatile component for power distribution and electrical infrastructure. Its construction from high conductivity copper ensures minimal resistance and efficient current transfer. The long barrel design provides ample surface area for robust compression, creating a secure and stable connection that minimizes the risk of failure. This splice is ideal for applications requiring dependable and long-lasting connections in demanding electrical systems.
