NSI 350T Dual Rated Single Lug – 350 MCM-6 AWG, 0.41″ Hole, 600V

Description

Product Overview

The NSI 350T Dual Rated Single Lug is engineered for demanding industrial environments where reliability and performance are non‑negotiable. Constructed from premium 6061‑T6 aluminum alloy, the terminal offers a perfect balance of strength, corrosion resistance, and lightweight handling. A tin‑plated finish further reduces contact resistance, ensuring a secure electrical connection that minimizes heat buildup even under continuous load. The lug is sized to accept 350 MCM‑6 AWG conductors, whether copper or aluminum, and features a 0.41″ mounting hole that aligns with standard panel cutouts. Rated for 600 V, it complies with rigorous UL and IEC standards, making it suitable for a wide range of applications from power distribution panels to heavy‑duty machinery. Its dual‑rated capability means it can safely handle both copper and aluminum conductors without the need for separate part numbers, simplifying inventory management and reducing procurement costs. The compact dimensions—0.99″ width, 1.13″ height, and 2.25″ length—allow for dense packing in tight panel spaces while maintaining ample clearance for heat dissipation.

Usage

Designed for versatility, the NSI 350T lug excels in a variety of industrial settings. It is ideal for use in power distribution cabinets, motor control centers, and switchgear where high current carrying capacity and secure fastening are essential. The lug’s reusable set‑screw mechanism enables quick installation and easy removal for maintenance or reconfiguration, saving valuable labor time. Its robust construction makes it suitable for harsh environments, including factories with high humidity, temperature fluctuations, and exposure to chemicals or dust. Whether you are wiring large‑scale manufacturing equipment, installing renewable energy inverters, or retrofitting legacy systems, this terminal provides a dependable connection point that meets or exceeds code requirements. The 600 V rating ensures compatibility with most medium‑voltage applications, while the 350 MCM‑6 AWG rating supports heavy‑duty conductors needed for high‑current circuits. Technicians appreciate the clear markings and ergonomic design that reduce the risk of mis‑installation, and the lug’s compatibility with standard torque tools guarantees consistent tightening across multiple installations.

FAQ

What size conductors can the NSI 350T lug accommodate?

The lug is rated for conductors up to 350 MCM‑6 AWG, which includes both copper and aluminum wire sizes commonly used in industrial power distribution. This range provides flexibility for a variety of applications, from heavy‑duty motor circuits to large‑scale panel wiring.

Is the lug compatible with both copper and aluminum conductors?

Yes, the NSI 350T is a dual‑rated terminal, meaning it has been tested and approved for use with both copper and aluminum conductors. The tin‑plated finish helps mitigate galvanic corrosion when aluminum is used, ensuring a stable and safe connection over the product’s lifespan.

What is the voltage rating and why is it important?

The terminal is rated for 600 V, which aligns with many medium‑voltage industrial standards. This rating indicates the maximum voltage the lug can safely handle without breakdown, providing assurance that it will perform reliably in typical power distribution and control panel environments.

How does the reusable set‑screw design benefit installation?

The set‑screw mechanism allows technicians to secure the conductor firmly and then release it without damaging the terminal. This reusability speeds up installation, simplifies future maintenance or upgrades, and reduces waste compared to crimp‑type connectors that are often single‑use.

What warranty and support does NSI Industries offer?

NSI Industries provides a one‑year limited warranty covering any material defects. In addition, customers have access to dedicated technical support, detailed installation documentation, and a responsive service team ready to assist with any product‑related inquiries.
