In-Line Wire Entry: Form secure connections between 2 conductors quickly using the in-line entry ports sized for wires between 1/0 and 14 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 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
Professional Performance: Save time and labor when splicing or reducing in-line wires made from copper or aluminum, in a wide range of applications
The Polaris ISR-1/0 2-Port In-Line Connector provides the simplest solution for forming a secure connection between two conductors in splicing and reducing applications including cable trays, panel boards, ducts, raceways or troughs. Sized for 1/0 - 14 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 aluminum alloy body is wrapped in high-dielectric strength plastisol insulation, which is ergonomically molded to offer a comfortable grip, in addition to being resistant to abrasion, chemicals and UV rays. All-in-one design saves time and supplies on each job by eliminating the need for cover and taping; simply brush the conductors clean, strip back their insulation, insert one conductor into each port and secure the covered pressure screws. The ISR-1/0 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 170 and 135 respectively. Polaris: the original pre-insulated connector and still the brand most asked for by name.
