Overview

The NSI Industries L250N is a Long Barrel Copper Compression Lug engineered for high-performance electrical terminations in demanding applications. Manufactured from high-conductivity copper tubing, this lug undergoes a tin-plated finish to deliver superior corrosion resistance while maintaining low contact resistance over time. The L250N is specifically designed to accommodate wire ranges from 250 MCM to 500 MCM, ensuring compatibility with a wide variety of heavy-duty conductors. With a temperature rating of 90°C and a voltage rating of 600V, the L250N is built to handle high thermal and electrical loads. When installed according to cable manufacturer instructions, it is rated for a maximum of 35KV, making it suitable for medium-voltage applications. For installations exceeding 2000V, users must follow the cable manufacturer’s voltage stress relief guidelines to ensure safe operation. The lug is exclusively designed for Class B or C building wire copper cable, ensuring optimal performance with standard copper conductors. The long barrel design of the L250N provides enhanced mechanical strength and strain relief, reducing the risk of conductor damage or pull-out under stress. This feature makes it ideal for critical applications in power distribution systems, motor control centers, and renewable energy installations, where reliability and durability are paramount. The lug includes a 1/2" bolt hole for secure mounting, allowing for easy integration into electrical panels, switchgear, and other equipment. NSI Industries, a US-based manufacturer, produces the L250N with precision engineering to meet industry demands for high-quality electrical components. For optimal installation, users should refer to the NSI catalog for specific tool and die crimping requirements, ensuring proper compression and long-term performance. The L250N combines durability, safety, and efficiency, making it a trusted choice for professionals in electrical construction and maintenance.
