Overview

The NSI Industries Polaris IT-350 Multi-Tap Dual-Side Entry Connector is a pre-insulated, 2-port splicing solution engineered for secure, high-current connections in industrial and commercial electrical systems. Designed for conductors ranging from 350 MCM to 6 AWG, this connector supports both copper and aluminum cables, making it a versatile choice for a wide range of applications. The IT-350 features a durable aluminum alloy body with a plastisol insulation layer, providing high dielectric strength and resistance to abrasion, chemicals, and UV exposure. Each port is pre-loaded with an oxide inhibitor to prevent corrosion and ensure long-term conductivity. Installation is simplified with removable access plugs and hex screws, requiring only a hex key and torque wrench—no additional tape or supplies needed. The connector is rated for 600V and operates at temperatures up to 90°C, with maximum amp ratings of 310A for copper and 250A for aluminum. Its dual-side entry design allows for flexible installation in cable trays, panel boards, ducts, raceways, or troughs, while the ergonomic molding ensures a comfortable grip during use. The IT-350 is part of NSI Industries' Polaris line of pre-insulated connectors, known for their reliability and ease of use in demanding environments.
