Eaton ENR22201 Receptacle Assembly - Hazardous Location
Part Number: ENR22201
Quick Summary
The Eaton ENR22201 receptacle assembly provides safe, reliable power connections for hazardous locations. In harsh industrial environments, downtime and maintenance costs rise when equipment isn’t built to endure corrosive atmospheres and demanding frequencies. The ENR22201 counters these challenges with copper-free aluminum construction, a two-gang footprint, and a dead-end style designed for quick, secure terminations. It carries NEC/CEC certifications and hazardous-location ratings across Class I, Division 1 and Division 2 and Class II, as well as Class III, plus NEMA protections 3, 7, 9, and 12. This combination supports code-compliant installation and long-term lifecycle value, reducing maintenance cycles while expanding safe power distribution for Ark-Gard ENR Value installations. Secondary benefits include compatibility with Ark-Gard ENR catalog guidance and a proven track record in demanding environments.
