Copper-free aluminum construction delivers robust corrosion resistance while keeping weight to a manageable level, easing handling and mounting in tight spaces. This translates to lower installation effort and longer service life in chemically harsh or outdoor environments, reducing maintenance cycles and downtime for control panels and instrument connections. The enclosure is engineered for hazardous and classified locations with NEC/CEC compliance and UL listings, providing essential safety and regulatory assurance. In practice, this reduces certification risk and accelerates project approval in oil, gas, and chemical facilities, supporting faster commissioning and fewer field rework items. With NEMA ratings 3, 4, 7, and 9, the EIHT230 offers proven protection against dust, water ingress, corrosion, and impact, enabling reliable operation across indoor and outdoor installations. The 2" blank cover on the power side and 4" glass lens cover on the instrument side, plus a 3/4" trade size entry, streamline wiring, visibility, and field upgrades while preserving enclosure integrity. Documentation and installation resources, including IF1179 and catalog pages, simplify procurement and on-site setup, minimizing project risk and speeding up handover. The compact footprint (5.19 in x 8.95 in x 5.19 in) and lightweight design (about 1 lb) help optimize enclosure density in control panels and instrument bays, reducing shipping costs and enabling scalable deployments across facilities.

FAQs
When installing EIHT230 in hazardous locations, ensure proper mounting orientation to align the instrument side with visibility needs and the power side for wiring access. Use the 3/4 inch trade size entry for standard conduit connections and route cables away from the glass lens to prevent glare. Follow installation sheets like IF 1179 for wiring and sealing procedures to maintain integrity and compliance.
EIHT230 supports NEC/CEC compliance and UL certifications for hazardous locations. It is rated for Class I, Division 1 and 2, Class II Division 1 and 2, and Class III, with NEMA ratings 3, 4, 7, and 9, enabling safe operation in a wide range of industrial environments. This combination helps meet regulatory requirements and simplifies project approvals.
Yes. The enclosure features a 3/4" trade size entry and a 2" blank cover on the power side, plus a 4" glass lens instrument side for visibility. These design choices support common control panel wiring practices, straightforward wiring access, and easy integration with standard instrumentation while preserving enclosure integrity and hazardous-location ratings.
Copper-free aluminum delivers excellent corrosion resistance, reducing maintenance in harsh environments. The material also keeps the enclosure lightweight, lowering handling and shipping costs and enabling quicker field installation. Over the life of the asset, the combination of durability and ease of servicing translates to lower total cost of ownership in challenging facilities.
Regular inspections should focus on seal integrity, lens clarity, and mounting hardware. Verify that the 2" blank power side cover and 4" glass lens instrument side remain secure and free of debris. Reference installation sheets such as IF 1179 and the catalog specifications for recommended torque values and replacement parts to sustain compliance and optimal protection.
