Overview

The Polaris ITO-4B 2-Port Offset Dual-Sided Connector provides the simplest solution for forming a secure connection between two conductors in applications including cable trays, panel boards, ducts, raceways or troughs. Sized for 4 - 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 ITO-4 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 95 and 75 respectively. Polaris pre-insulated connectors are available in a range of port numbers and configurations to fit the needs of any job, including UL-listed parallel configurations. Polaris: the original pre-insulated connector and still the brand most asked for by name.
  • Offset Wire Entry: Form secure connections between 2 conductors quickly using the offset entry ports sized for wires between 4 and 14 AWG
  • Ergonomic Design: Rounded corners and a smooth exterior finish over the plastisol insulation make Polaris connectors comfortable to grip
  • Removable Plugs: Each port and adjustable set screw is covered by a secure plug to prevent debris, moisture or contaminants from entering the insulated connector
  • Pre-filled Oxide Inhibitor: Both offset entry ports come pre-filled with an oxide inhibitor gel to prevent corrosion and provide low-contact resistance
  • Professional Performance: The durable layer of insulation on each Polaris connector is UV, abrasion and chemical-resistant for reliable performance
