Overview

The NSI Industries AL3/0-48 is a high-conductivity aluminum compression lug designed for reliable electrical connections. Manufactured from premium aluminum tubing, this lug ensures excellent conductivity and durability. It features a standard barrel design with a single mounting hole and is engineered to accommodate 3/0 AWG conductors, with a 1/2" bolt size for secure fastening. A crucial design element is the center stop, which guarantees precise and proper cable installation, preventing over-insertion and ensuring a consistent crimp. For enhanced longevity and performance in various environments, the AL3/0-48 is electro-tin plated. This plating provides superior corrosion resistance, protecting the lug from environmental degradation and maintaining low contact resistance over time. The lug is clearly marked with die index information and color-coded (Tan for this specific model), facilitating easy identification and selection during installation. This color-coding system, along with the die index, streamlines inventory management and reduces the potential for errors. This compression lug is cULus Listed and UL486A/B Listed for wire connectors, meeting stringent industry safety and performance standards. It is also UL Listed for 35KV maximum when properly installed according to cable manufacturer specifications, making it suitable for medium-voltage applications. The temperature rating is 90°C, and it is compatible with NSI crimp tools N1240 and N121D. The voltage rating is 600V maximum, or 2000V maximum per UL486B. The AL3/0-48 is manufactured in the USA, ensuring quality and adherence to domestic manufacturing standards. Its robust construction and adherence to critical electrical codes make it a dependable choice for power distribution and industrial electrical systems.
