The Polaris IPLG3/0-4 4-Port Single-Side Connector provides the simplest solution for forming a secure connection between up to four fine-stranded wire conductors in applications including cable trays, troughs, wire-ways, raceways, ducts and motor junction boxes. Sized for 3/0 - 4 AWG wires and rated for 600V, this connector 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 to crumple the tin-plated copper ferrule down against the wires, forming a strong connection without tearing wires. The IPLG3/0-4 connector is rated for a 90 degrees Celsius operating temperature and copper cables up to max AMP ratings of 400. 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.
