Overview

The Polaris ISPBO2/0B 3-Port Offset Entry Submersible Connector provides the simplest solution for forming a secure connection between up to three conductors in direct burial or temporary submersal applications with a wide range of wire sizes. Sized for 2/0 - 14 AWG wires and rated for 600V, this pre-insulated connector comes pre-loaded with an oxide inhibitor and installs faster than traditional connector options using just a hex key and torque wrench. The aluminum alloy body is wrapped in high-dielectric strength rubber insulation with a nominal thickness of 125 mils, which is ergonomically molded to offer a comfortable grip and is resistant to abrasion, chemicals and UV rays. Meets or exceeds UL486D and ANSI C119.1 specifications for use in temporary submersion, direct burial, or damp locations subject to occasional flooding. 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 radial tipped set-screws. The ISPBO2/0 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 195 and 150 respectively. Polaris: the original pre-insulated connector and still the brand most asked for by name.
  • Offset Wire Entry: Form secure connections between 3 conductors quickly using the offset entry ports sized for wires between 2/0 and 14 AWG
  • Direct Burial Applications: High-strength aluminum alloy body and rubber insulation with a nominal thickness of 125 mils built for temporary submersal or direct burial applications
  • Ergonomic Design: The plastisol insulation features rounded corners for a comfortable grip and is UV, abrasion and chemical-resistant for durable performance
  • Pre-filled Oxide Inhibitor: All 3 offset entry ports are covered by removable plugs and pre-filled with an oxide inhibitor gel to prevent corrosion or contamination
  • Professional Performance: The durable layer of insulation on each Polaris connector is UV, abrasion and chemical-resistant for reliable performance
