The Polaris IPLD500-6B 6-Port Dual-Sided Connector provides the simplest solution for forming a secure connection between up to six conductors in applications including cable trays, panel boards, ducts, raceways or troughs. Sized for 500 MCM - 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 IPLD500-6B 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 1209 and 946 respectively. These connectors are even UL-listed for parallel configurations, allowing you to tackle larger jobs safely. Polaris: the original pre-insulated connector and still the brand most asked for by name.
