Overview

The Woodhead Safeway® Plug with Locking Blade (SKU: 28T81) is a 30A, 4-pole/5-wire NEMA L21-30 industrial connector designed for 3-phase Y-connected systems at 208V. This heavy-duty plug features a nickel-plated brass blade and contact system for corrosion resistance and long service life. The NEo-TEX® Paracril OZO rubber housing delivers superior performance in abrasion, chemical exposure, and extreme temperatures from -40°C to 75°C. Key features include color-coded ¼" terminal screws pre-set in open position, tri-drive wire screw terminals compatible with straight blade, Phillips, and square-drive screwdrivers, and a floating blade construction for self-alignment and reduced wear. The transparent wiring guide ensures proper wire strand placement before securing, while the captive stainless steel speed screws enable quick assembly and long-term reliability. A two-piece cord-clamp strain relief with tri-drive screws secures cords firmly. UL File No. E10176 and CSA File No. LR6837 certified for global compliance. Ideal for CNC machines, welders, pumps, HVAC systems, and temporary power setups in construction, manufacturing, and data centers.
