Overview

The Woodhead Super-Safeway® Connector with Locking Blade (SKU 2782) is a 4-pole, 5-wire industrial-grade power connector designed for 3-phase 480V applications. Engineered to NEMA L22-20 standards, this connector ensures secure, vibration-resistant connections critical in heavy-duty environments. Its nickel-plated brass contacts and NEo-TEX® Paracril OZO rubber housing deliver superior resistance to abrasion, chemicals, and extreme temperatures (-40°C to 75°C). The floating blade construction minimizes wear and heat generation, while the captive tri-drive stainless steel screws enable tool-free assembly and long-term reliability. The transparent wiring guide confirms proper wire strand placement, and the two-piece cord-clamp strain relief secures cables firmly. Ideal for powering generators, machinery, and process equipment in industrial facilities, this connector’s UL E10176 and CSA LR6837 certifications validate its safety and performance.
  • 4-pole/5-wire configuration for 3-phase 480V power distribution

Solar combiners (solar panel combiner boxes) are engineered to combine power from several solar panels onto a common bus. They are specially designed for the types of wiring used in photovoltaic (PV) systems. The output would then be connected to a charge controller or inverter depending on the type of system. Solar combiners also allow for a transition to larger wires between the array and the batteries or inverter to minimize transmission voltage drop all while protecting the array. Streamline now offers a variety of premium plug and play solar combiner box solutions. Built in Streamlines UL 508-A panel shop just outside of Milwaukee Wisconsin these systems can be trusted to perform. All combiner boxes are hand-assembled using best-in-class name brand components and are built to stand up under even the harshest conditions. In addition they are highly serviceable. The polycarbonate enclosure features a full-length piano-hinged door with a non-metallic latch. They offer a variety of mounting options thanks to brass inserts on the rear wall of the enclosure and the lid. Made in the U.S.A the enclosures are UL/cUL NEMA Type 6P IP68 as well as UV and chemical resistant.

The Polaris SP4 Set Screw Plug is a replacement part that take the place of the secure removable plugs present in many Polaris pre-insulated connectors. This plug fits connectors sized for 4 AWG wires, covering the set screws used to tighten their connections. Protect the interior of your Polaris pre-insulated connectors, each port of which is pre-loaded with an oxide inhibitor to ensure a low-contact resistance connection, by guarding the set screws from outside contaminants. Polaris designs connectors for use in a wide range of splicing applications, including installation in cable trays, panel boards, ducts, raceways or troughs.
