Overview

The NSI Industries Polaris ITH-750 Multi-Tap Dual-Sided Entry Connector is a heavy-duty, pre-insulated splicing solution engineered for secure, high-current connections in demanding industrial environments. This 2-port connector supports wire sizes from 750 MCM down to 1/0 AWG, making it ideal for high-amperage applications where copper and aluminum conductors must be joined reliably. The connector features dual-sided entry ports with removable access plugs, allowing installation flexibility in cable trays, panel boards, ducts, raceways, or troughs without additional tools beyond a hex key and torque wrench. Constructed from a durable aluminum alloy body with a plastisol insulation wrap, the ITH-750 delivers exceptional resistance to abrasion, chemicals, and UV exposure while maintaining a dielectric strength suitable for 600V systems. Each port includes two pressure screws and is pre-loaded with an oxide inhibitor to ensure low-resistance, long-term connections. The connector is dual-rated for 535A with copper conductors and 435A with aluminum, operating efficiently at up to 90°C. Designed for rapid installation, the ITH-750 eliminates the need for tape, solder, or specialized supplies. Simply clean the conductors, strip the insulation, insert one wire into each port, and tighten the hex screws to the specified torque (175–225 in-lbs). The removable access plugs allow unused ports to be sealed, reducing contamination risks in harsh environments. With a compact footprint of 70 3/16 inches in length, width, and height, this connector integrates seamlessly into tight spaces while delivering maximum performance in parallel configurations. NSI Industries' Polaris series remains the industry standard for pre-insulated connectors, trusted for over 50 years in splicing applications across power distribution, renewable energy, and industrial facilities.
  • Dual-Sided Wire Entry: Form secure connections between 2 conductors quickly using the double-side entry ports sized for wires between 750 MCM and 1/0 AWG
  • 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: Both dual-sided entry (DSE) ports come pre-filled with an oxide inhibitor gel to prevent corrosion and provide low-contact resistance
