FAQs

The ENRX21201 S752 is a single-gang receptacle designed for 3/4" trade size installations and fits conventional hazardous-location enclosures. Its NEMA 5-20R configuration supports common cords and devices, while the external epoxy coating and copper-free aluminum body enhance durability in Class I Division 2 and Zone 2 environments, simplifying panel wiring and reducing retrofit complexity.
This receptacle assembly carries NEC/CEC compliance for hazardous locations, with Class I Division 2 and Zone 2 ratings, IP66 ingress protection, and NEMA 4X enclosure protection. These certifications ensure safe operation in corrosive, dusty, and wet conditions typical of chemical plants, offshore platforms, and mining facilities.
Ideal for hazardous-location power connections in oil and gas, chemical processing, marine, and heavy-industrial settings. The 20A, 125 VAC rating and 5-20R NEMA configuration support standard equipment loads, while IP66/NEMA 4X guarding ensures continued performance in challenging environments.
It provides a compact, dead-end, single-cover design for straightforward terminations in single-gang boxes. The copper-free aluminum body with external epoxy coating combats corrosion, and the 3/4" trade size reduces space constraints in tight enclosures, contributing to faster, safer field wiring and maintenance.
Durable materials (copper-free aluminum) and harsh-environment protection (IP66, NEMA 4X) lead to fewer corrosion-related failures and longer service intervals. Combined with easy installation and NEC/CEC compliance, this translates to lower maintenance costs, reduced downtime, and improved reliability for hazardous-area electrical systems.
