Overview

The NSI Industries Polaris IT-750 Multi-Tap Dual-Side Entry Connector is a pre-insulated, 2-port splicing solution engineered for high-current applications requiring secure, reliable connections between 750 MCM and 250 MCM copper or aluminum conductors. Rated for 600V and up to 475A (copper) or 385A (aluminum) at 75°C, this connector eliminates the need for traditional uninsulated splicing methods by integrating oxide inhibitors, hex screw terminals, and removable access plugs for unused ports. The aluminum alloy body is coated with high-dielectric strength plastisol insulation, providing abrasion, chemical, and UV resistance while ensuring non-combustibility. Designed for installation in cable trays, panel boards, ducts, raceways, or troughs, the IT-750 simplifies splicing workflows by requiring only a hex key and torque wrench—no additional tape, covers, or supplies are needed. Each port is pre-loaded with oxide inhibitor to prevent corrosion, and the ergonomic design includes a molded grip for comfortable handling during tight installations. The connector’s dual-side entry ports allow for flexible conductor routing, with removable plugs sealing unused openings to maintain environmental protection. Ideal for industrial, commercial, and utility applications, the IT-750 is part of the Polaris series, a trusted brand in pre-insulated connectors. Compatible with UL-listed parallel configurations, this connector meets the demands of high-current splicing while reducing labor time and material costs compared to traditional methods.
