Overview

The NSI Industries Polaris IPLDH750-4 Multi-Tap Dual-Sided Entry Connector is a heavy-duty, pre-insulated solution for secure, high-current splicing applications. Designed for conductors ranging from 750 MCM to 250 MCM, this 4-port connector supports both copper and aluminum cables with maximum ampacities of 1178A (copper) and 930A (aluminum). The heavy-duty body is constructed from aluminum alloy, providing durability and corrosion resistance, and is wrapped in a layer of high-dielectric strength plastisol insulation. This insulation offers abrasion, chemical, and UV resistance while preventing combustion, ensuring long-term reliability in harsh environments. Each dual-sided port is pre-loaded with an oxide inhibitor to maintain optimal conductivity and includes removable access plugs over the hex screws used to tighten the connections. The design features two pressure screws per port to ensure the best connection possible in demanding applications, minimizing the risk of loose or unreliable splices. Installation is straightforward, requiring only a hex key and torque wrench set to 550 in-lbs, eliminating the need for tape or additional supplies. The connector is rated for 600V and operates at temperatures up to 90°C, making it suitable for a wide range of demanding environments. The IPLDH750-4 is engineered for versatility, with applications including installation in cable trays, panel boards, ducts, raceways, or troughs. Its compact dimensions of 6.380" (L) x 4.460" (W) x 3.300" (H) allow for easy integration into tight spaces while maintaining robust performance. As part of NSI’s Polaris series, the connector meets industry-first UL Listed 486A/B compliance, ensuring code-compliant ampacity ratings for parallel conductors. The standard carton quantity is 2 units, providing convenience for bulk installations.
  • Dual-Sided Wire Entry: Form secure connections between 4 conductors quickly using the double-side entry ports sized for wires between 750 and 250 MCM
  • Heavy-Duty Performance: Wider and stronger connector blocks feature two pressure screws for each cable to ensure a secure connection in demanding applications
  • Ergonomic Design: Rounded corners and a smooth exterior finish over the abrasion-resistant plastisol insulation make Polaris connectors comfortable to grip
  • Removable Plugs: Each port and set screw comes with a secure plug to prevent debris from entering the insulated connector
  • Pre-filled Oxide Inhibitor: All 4 dual-sided entry (DSE) ports come pre-filled with an oxide inhibitor gel to prevent corrosion and provide low-contact resistance
