Feature → Business Impact → Application: The ENR21201 S752 uses copper-free aluminum, delivering excellent corrosion resistance in salt spray and humid environments, which translates to lower maintenance costs and longer service life in offshore rigs and chemical processing facilities. This material choice supports a total cost of ownership advantage by minimizing replacement cycles and downtime during inspections, particularly in hazardous-area receptacle installations where reliability is non-negotiable. Application: use in single-gang installations with a 3/4" trade size and 5-20R NEMA configuration for 125 Vac circuits up to 20A, enabling safe, code-compliant power distribution in confined enclosures. The corro-free epoxy powder finish further protects against environmental degradation, reducing rework and service calls in rugged industrial settings. Feature → Compatibility & installation efficiency → Application: designed for Ark-Gard ENR Value compatibility and easy mounting within standard electrical layouts, accelerating commissioning in hazardous environments. This also supports faster changeouts during plant revamps without compromising safety or compliance.
