Overview

The NSI Industries 250T is a high-strength, reusable 1-port aluminum lug designed for secure, low-resistance connections with 250 MCM to 6 AWG conductors. Constructed from 6061T-6 aluminum alloy and electro-tin plated, this set-screw connector ensures minimal contact resistance while supporting both copper and aluminum conductors—eliminating the need for separate lugs in mixed-metal applications. The 250T is UL 486A/B listed for 600V operation (2000V max per UL486B) with a 90°C temperature rating, making it suitable for industrial, commercial, and utility environments. The set-screw design allows for tool-free installation and reconfiguration, reducing maintenance time and inventory complexity. With a reusable design, the 250T minimizes long-term costs by eliminating the need for replacement connectors in temporary or reconfigurable setups. Applications span power distribution panels, renewable energy systems, utility substations, and motor control centers. The dual-rated compatibility simplifies procurement by eliminating the need for separate copper and aluminum lugs, streamlining supply chains and reducing operational overhead. The 250T’s robust construction ensures reliable performance under demanding conditions, including high-vibration environments and corrosive atmospheres.
