Overview

The Woodhead Safeway® Flanged Receptacle (SKU: 2781MB) delivers secure, reliable 3-phase 208V power connections for industrial environments. Rated at 20A with a NEMA L21-20 configuration, this 4-pole/5-wire device ensures stable mounting via its flanged design while preventing accidental disconnections with a locking blade mechanism. Ideal for heavy-duty applications in manufacturing, automation, and machinery, it withstands abrasion, chemicals, and extreme temperatures (-40°C to 75°C) thanks to its NEo-TEX® Paracril OZO rubber housing and Nylon construction. Nickel-plated brass contacts guarantee consistent electrical performance, while tri-drive wire screw terminals accommodate straight blade, Phillips, and square-drive screwdrivers for flexible wiring. The floating blade design self-aligns to reduce wear and heat generation, and a transparent wiring guide ensures proper strand placement. UL File No. E10176 and CSA File No. LR6837 certified for compliance and safety.
