Overview

The NSI Industries Polaris ITO-3/0 Multi-Tap Offset Dual-Side Entry Connector is a pre-insulated, 2-port splicing solution engineered for secure, high-current connections in industrial and commercial wiring systems. Designed for 3/0 to 6 AWG copper or aluminum conductors, this connector delivers a rated 600V and supports up to 200A for copper cables and 155A for aluminum cables, making it ideal for heavy-duty applications. The aluminum alloy body is wrapped in high-dielectric strength plastisol insulation, providing abrasion resistance, chemical resistance, and UV stability while preventing combustion. Each port is pre-loaded with an oxide inhibitor to ensure long-term conductivity and reliability. The dual-side entry design allows for flexible installation in cable trays, panel boards, ducts, raceways, or troughs, with removable access plugs enabling unused ports to be sealed. Installation requires only a hex key and torque wrench (175-225 in-lbs), eliminating the need for tape or additional supplies. The connector measures 1.93 inches in length, 1.83 inches in width, and 1.83 inches in height, with a 1/4-inch hex wrench size. Suitable for cold temperatures down to -45°C, the ITO-3/0 is UL Listed for dry locations and dual-rated for both copper and aluminum cables, excluding fine-stranded, flexible wire. This all-in-one design reduces installation time and material costs by simplifying the splicing process, ensuring a secure, maintenance-free connection in demanding environments.
