Watertight sealing and IP67/NEMA 6 protection guard against water and dust ingress, reducing downtime and extending service life in wet or wash-down zones. This translates to fewer maintenance calls and more uptime on critical equipment in automation cabinets and outdoor installations. The 20A, 3-pole, 4-wire configuration (L16-20) supports standard 3Ø loads at 480V, enabling seamless integration with existing motor starters and drive systems. Back wiring for #18-10 AWG simplifies field terminations, speeding up installation and improving termination reliability while reducing commissioning time. Nickel-plated brass contacts paired with Santoprene seals ensure corrosion resistance and a tight, durable connection in harsh environments, decreasing replacement costs over the life of the installation. The nylon face/body gives a lightweight yet rugged housing, contributing to easy handling and consistent engagement in dense panel layouts. With a torque rating of 14–16 lbf-in, installations stay secure without over-tightening, supporting operator safety and equipment protection.
