Overview

The NSI Industries SL250N is a high-conductivity copper stacked compression lug designed for robust electrical connections. This long barrel lug is engineered from premium copper tubing, ensuring excellent conductivity and durability for heavy-duty applications. It is specifically designed for use with the NSI L-N series connectors, providing a reliable termination point for conductors ranging from 250 MCM down to 1/0 AWG. The SL250N features a 1/2" bolt size and a mounting hole spacing of 1.750 inches, facilitating secure and stable installations. To enhance longevity and performance, the SL250N is tin-plated, offering superior corrosion resistance and low contact resistance. This plating is crucial for maintaining connection integrity in various environmental conditions. For ease of identification and inventory management, each lug is clearly marked with its die index and color-coded, simplifying the crimping process and ensuring the correct tooling is used. The lug is UL486A Listed, meeting stringent safety and performance standards. It has a temperature rating of 90°C and a voltage rating of 600V, making it suitable for a wide range of industrial power distribution systems. Furthermore, when properly installed, the SL250N is listed for up to 35KV maximum, demonstrating its capability for high-voltage applications. The long barrel design ensures a substantial surface area for compression, leading to a secure and low-resistance electrical connection. The dimensions include a length (L) of 5.500 inches, a width (W) of 1.160 inches, and a barrel length (B1) of 2.870 inches, with an end connection to center (A) of 0.640 inches and a tang length (B) of 2.220 inches. Each standard carton contains 25 units, providing an efficient supply for project needs. The SL250N is an essential component for reliable and safe electrical terminations in demanding industrial environments.

How to Install the SL250N Compression Connectors

This guide provides step-by-step instructions for installing and configuring SL250N compression connectors for copper conductors.

Estimated time: 30m

Tools needed:

Wire strippers, Crimping tool, Multimeter

Supplies needed:

Copper compression connectors, Wire brush, Terminal connectors

  1. Select the appropriate connector

    Choose the correct size of copper compression connector based on the gauge of the wire being used, ensuring it matches the specifications in the provided chart.

  2. Strip the wire insulation

    Carefully strip the insulation from the conductor without damaging the strands, ensuring the stripped length allows the conductor to fill the connector barrel completely.

  3. Clean the conductor

    Use a wire brush to clean the stripped portion of the conductor to remove any oxide films, ensuring a good electrical connection.

  4. Insert the conductor into the connector

    Insert the cleaned and stripped conductor completely into the barrel of the connector, ensuring it is fully seated.

  5. Crimp the connector

    Utilize the appropriate crimping tool to crimp the connector securely onto the conductor, following the manufacturer's suggested crimp locations.

  6. Verify the connection

    Use a multimeter to check the continuity and resistance of the connection to ensure it is secure and functioning properly.
