Overview

The Polaris ISRH-750C 2-Port In-Line Connector provides the simplest solution for forming a secure, heavy-duty connection between two conductors in splicing and reducing applications including cable trays, panel boards, ducts, raceways or troughs. Sized for 750 MCM – 1/0 AWG wires and rated for 600V, this pre-insulated connector comes pre-loaded with an oxide inhibitor and installs faster than traditional uninsulated connector options using just a hex key and torque wrench. The clear body lets installers see their work for optimal conductor placement and is ergonomically molded to offer a comfortable grip, in addition to being resistant to abrasion and chemicals. All-in-one design saves time and supplies on each job by eliminating the need for cover and taping; simply strip back their insulation, brush the conductors clean, insert one conductor into each port and secure the covered pressure screws. The ISRH-750C connector is rated for a 90 degrees Celsius operating temperature and dual rated for use with copper and/or aluminum cables, up to max AMP ratings of 535 and 435 respectively. Polaris: the original pre-insulated connector and still the brand most asked for by name.
  • Clear Exterior: Vision Tap transparent design lets users see their work to ensure ideal conductor placement and the most secure connection
  • In-Line Wire Entry: Form heavy-duty connections between 2 conductors quickly using the in-line entry ports sized for wires between 750 MCM and 1/0 AWG
  • 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 both pairs of set screw comes with a secure plug to prevent debris from entering the insulated connector
  • Pre-filled Oxide Inhibitor: Both in-line ports come pre-filled with an oxide inhibitor gel to prevent corrosion and provide low-contact resistance
