EZD311 carries NEC/CEC compliance with Class I Division 1 and 2, Class II Division 1 and 2, and Class III ratings, plus Hazardous/Classified Locations area classification. These ratings confirm suitability for explosive atmospheres and help satisfy regulatory and safety requirements in oil & gas, chemical processing, and other hazardous environments.
Industries such as oil and gas, chemical processing, mining, power generation, and water treatment benefit most. The combination of drain capability, inspection access, and explosionproof sealing supports reliable operation in harsh, moisture-prone environments where electrical equipment must stay protected and compliant.
UL certification information is available in the product’s downloads, including UL certification reports. These documents validate compliance for use in hazardous locations and support quality assurance during procurement and inspection. Cross-reference with the UL pages listed in the downloads to confirm specifics for your region.
The integrated drain reduces moisture ingress, helping prevent corrosion and ingress-related failures. The inspection cover enables easier access for routine checks and drainage maintenance, which lowers downtime and extends service intervals in harsh environments. Together, they deliver improved reliability and lower total cost of ownership.
