Overview

The Woodhead Super-Safeway® Connector (SKU: 2781) is a robust industrial-grade connector designed for 3-phase 208V power distribution. This 4-pole/5-wire connector features a NEMA L21-20 configuration and a locking blade mechanism for secure connections. Constructed with NEo-TEX® Paracril OZO rubber, it offers superior resistance to abrasion, chemicals, and extreme temperatures (-40°C to 75°C continuous). The floating blade design ensures self-alignment and minimizes wear, while tri-drive wire screw terminals facilitate easy wiring with various screwdriver types. Its transparent wiring guide allows for visual confirmation of wire placement. The captive, stainless steel speed screw and two-piece cord-clamp strain relief with tri-drive screws ensure long life and secure cable management. Applications include manufacturing facilities, construction sites, data centers, and warehouses requiring reliable 3-phase power. It meets UL File No. E10176 and CSA File No. LR6837 standards. The connector's nickel-plated brass contacts and durable construction make it suitable for demanding industrial environments.
