The 20A at 250V rating aligns with standard industrial loads, enabling direct replacement for existing receptacles without major panel modifications. This reduces wiring changes, speeds commissioning, and improves uptime in hazardous locations such as chemical plants and oil-and-gas facilities. The copper-free aluminum housing offers superior corrosion resistance in harsh environments, extending service life and lowering maintenance costs on offshore platforms and processing sites. With a 50-400 Hz frequency rating, the ENR21202 M4 supports variable-frequency drives and mixed-power systems, delivering flexible performance in marine and industrial applications. Its single-gang, 3/4" trade size footprint simplifies panel layouts, reduces install time, and enables straightforward retrofits in space-constrained enclosures. The NEMA configuration 6-20R paired with a dead-end style provides robust, safer terminations, aiding rapid field servicing and minimizing downtime. UL-listed and NEC/CEC compliant, this receptacle fits seamlessly into the Ark-Gard ENR Premier ecosystem, ensuring regulatory conformity, compatibility with replacement covers (IF 1424), and access to comprehensive installation documentation. These design choices translate to measurable uptime gains, predictable maintenance planning, and cost containment across hazardous-area operations.
