Overview

The Woodhead 420MI7W is a 20 Amp, 3-pole/4-wire Pin & Sleeve Mechanical Interlock with a flip lid, designed for 480V applications in wet or harsh industrial environments. This IP67-rated device features a durable Type G nylon housing and brass pins, ensuring reliable performance in washdown areas, outdoor installations, and temporary power systems.
