The Polaris IT-500 2-Port Dual-Side 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 500 MCM to 4 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 IT-500 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 380 and 310 respectively. Comes with removable access plugs to close whichever side of the entry ports are not being utilized. 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.
