FAQs
ENR12202 M4 uses a 6-20R NEMA configuration in a two-gang, dead-end assembly rated for 250 VAC and 20 A. The copper-free aluminum body provides corrosion resistance, while the double cover offers protection against dust and moisture intrusion. This combination supports reliable, lockable connections in hazardous areas and simplifies spare-parts planning for maintenance teams.
The ENR12202 M4 is designed to meet NEC/CEC standards for hazardous locations and is rated for Hazardous/Classified Locations. It carries a NEMA rating set (3, 3R, 7, 9, 12) to ensure appropriate enclosure protection. These certifications help ensure regulatory compliance, safer operation, and consistent performance across industrial environments, reducing regulatory risk and enabling easier audits.
Yes. ENR12202 M4 is specified for Class I, Division 1 and Division 2, Class II, Division 1 and 2, Class III environments, aligning with NEC hazardous-location requirements. Its explosionproof construction and Ark-Gard ENR Premier design mitigate ignition risks, supporting compliant installation in equipment rooms, process areas, and offshore platforms where flammable atmospheres may be present.
Plan for a copper-free aluminum housing with a 1/2" trade size and a two-gang footprint to fit standard enclosures. Verify that the conduit entries and wiring methods meet local codes, ensure correct lockout/tagout practices, and use compatible Ark-Gard ENR covers when performing maintenance or replacement. The product’s weight around 1 lb aids handling in confined spaces.
The aluminum construction reduces corrosion-related maintenance and weight, contributing to lower lifecycle costs. The robust NEC/CEC compliance and NEMA protection lessen the likelihood of non-conformance penalties and unplanned downtime. Over multiple sites, standardized ENR Premier receptacles simplify training, spares management, and future upgrades, delivering a favorable total cost of ownership.
