Through-feed design simplifies wiring and minimizes panel disruption during installation, speeding up commissioning in hazardous-location environments. The 3/4" trade size and 5-20R NEMA configuration align with standard power layouts, reducing need for adapters and custom fabrication. Field technicians benefit from a straightforward single-gang footprint that fits compact enclosures without sacrificing reliability. Copper-free aluminum construction paired with a corro-free epoxy powder finish delivers exceptional corrosion resistance in salt spray, chemical areas, and humid facilities. This durability translates into longer service life, fewer maintenance cycles, and tangible cost savings over the asset lifecycle. The combination is well-suited for marine, offshore, and process industries where aggressive environments challenge conventional receptacles. Compliance is built in. The ENRC21201 S752 carries NEC/CEC certifications for Hazardous/Classified Locations and supports NEC hazardous ratings across Class I and II and Division 1 and 2, complemented by compatible NEMA ratings of 12, 7, 3, and 9. This broad certification suite accelerates approvals, simplifies supplier onboarding, and reduces risk on multi-site projects. Ark-Gard ENR Value compatibility ensures consistent performance with other Ark-Gard components, simplifying procurement and spare parts management. The unit's 125 Vac, 20A rating, 50-400 Hz frequency range, and single-gang form factor are designed for quick installation in new builds or retrofits, while the 5-20R configuration supports common industrial plug types. Installation and lifecycle benefits include reduced maintenance downtime thanks to copper-free aluminum and corrosion-resistant epoxy finish, easier replacement and sourcing through the Ark-Gard ENR Value catalog pages, and predictable performance in harsh environments. For project owners, these attributes support faster turnover, lower total cost of ownership, and improved safety compliance across hazardous-area installations.
