FAQs
Yes. ENRX21201 is configured as a single-gang 5-20R receptacle with a 3/4" trade size, designed for 125 VAC operation at 50-400 Hz. This allows direct mating with standard 5-20P locking devices you typically use in NEC/CEC-compliant systems, simplifying panel layouts and reducing adapter clutter in hazardous-area installations.
ENRX21201 features an IP66 ingress protection rating and a NEMA 4X enclosure, suitable for exposure to water, dust, and corrosive environments. It also carries Class I, Division 2 / Zone 2 hazardous-location ratings, aligning with stringent national and international standards for electrical equipment in classified spaces.
Ideal for oil and gas, chemical processing, mining, and marine applications, ENRX receptacles are designed for harsh, space-constrained environments. Their rugged enclosure, corrosion resistance, and robust power connections make them well-suited for offshore platforms, refineries, and industrial plants requiring reliable, code-compliant power distribution.
ENRX21201 carries NEC/CEC compliance, and hazardous-location ratings including Class I Division 2 and Zone 2, along with IP66 ingress protection and NEMA 4X enclosure. These certifications support regulatory acceptance and simplify procurement for projects with strict safety and performance requirements.
The copper-free aluminum construction resists corrosion and reduces weight, easing installation and field servicing. The IP66/NEMA 4X protection and hazardous-location ratings minimize downtime due to ingress or corrosion, while compatible 5-20R configurations reduce adapter costs. Over the equipment lifecycle, this yields lower maintenance costs and improved uptime for critical operations.
