Overview

The NSI Industries Polaris PL4-6 Uninsulated Multi-Tap Connector is a 6-port splicing solution engineered for secure, high-current connections in industrial and commercial wiring systems. Designed for conductors sized 4 to 14 AWG, this connector supports both copper and aluminum cables with maximum amp ratings of 95A (copper) and 75A (aluminum). The 2000V-rated aluminum alloy body is corrosion-resistant and operates reliably from -45°C to 90°C (-49°F to 194°F), making it suitable for harsh environments. Installation is simplified with a hex key and torque wrench—no tape or additional supplies required. Each of the six pass-through ports features a hex screw for precise torque control, ensuring consistent, low-resistance connections. The ergonomic rounded corners enhance grip during tightening, reducing operator fatigue on long jobs. The uninsulated design allows for direct visual inspection of conductor placement, enabling quick verification of secure terminations. Ideal for use in cable trays, panel boards, ducts, raceways, and troughs, the PL4-6 connector is optimized for parallel runs and dry locations. Its dual-rated compatibility with Class B and C conductors ensures versatility across a wide range of applications, from motor control centers to distribution panels. The 6061-T6 aluminum construction provides durability while maintaining lightweight handling. Available in multiple port configurations, the Polaris PL4-6 is part of NSI Industries' trusted line of multi-tap connectors, trusted by electricians and engineers for decades. Whether splicing branch circuits or extending feeders, this connector delivers reliable performance with minimal installation time.
  • Uninsulated Simplicity: Form secure connections between 6 conductors quickly using the pass-through entry ports sized for wires between 4 and 14 AWG
  • Functional Design: Rounded corners and a plated aluminum body make Polaris connectors comfortable to grip and durable for harsh environments
  • Tightens Fast: Each entry port features a hex-keyed set screw that can be easily tightened to provide a secure grip on the inserted conductor
  • Extreme Voltage: Choose uninsulated connectors for high-voltage connections, with a heavy-duty maximum voltage rating of 2000V
  • Best Connections: Aluminum alloy pass-through ports provide low-contact resistance to guarantee a strong connection
