Eaton Specification Sheet - EMH533 20200
Feature: Copper-free aluminum enclosure reduces weight while resisting corrosion in outdoor and chemical settings. Business impact: Easier handling in the field and lower mounting stress, which translates to fewer worker injuries and faster asset deployment. Application: Ideal for outdoor substations and process areas where moisture and humidity are present, such as chemical plants and oil/gas facilities. Feature: Two conduit openings support flexible wiring configurations and splices. Business impact: You can route conductors neatly and minimize field modifications, saving time during commissioning. Application: Suitable for through-feed arrangements in surface-mounted housings near meters from GE and Weston. Feature: Surface mounting and through-feed style simplify installation and wiring access. Business impact: Reduces installation steps, improves serviceability, and lowers labor cost. Application: Panels and instrument enclosures where meter interfaces require straightforward top access. Feature: Compact 5.75 in length/height with a 5 lb weight; manageable form for tight spaces. Business impact: Easier handling during maintenance and reduced need for heavy lifting equipment. Application: Space-constrained industrial panels and field-mounted meter housings. Feature: NEC/CEC compliance, Hazardous/Classified Locations area classification, and NEMA ratings 3, 7, 9, 12. Business impact: Ensures regulatory alignment, minimizes risk, and streamlines procurement with a single enclosure for multiple environments. Application: Hazardous locations and industrial facilities; use with select GE and Weston meters.

FAQs
The EMH533 20200 is specified for use with select GE and Weston meters, leveraging its 3/4" trade size, 2 conduit openings, and through-feed wiring. Its surface-mount design simplifies mounting adjacent to meters, reducing wiring runs and enabling reliable connections in hazardous environments.
This enclosure carries NEC/CEC compliance and area classification for Hazardous/Classified Locations, along with NEMA ratings 3, 7, 9, and 12. These certifications support safe operation in hazardous environments and align with regulatory requirements for industrial installations.
Yes. The through-feed, surface-mount configuration is optimized for compact installations. With two conduit openings and a 5.75 in footprint, it fits in constrained panels and service areas while providing straightforward wiring access for maintenance and meter interfacing.
Two conduit openings enable flexible conduit routing and splicing. Ensure compliance with conduit fill calculations and local codes, route conductors neatly, and maintain seal integrity to preserve the enclosure’s hazardous-location ratings during field assembly.
Copper-free aluminum offers corrosion resistance with lighter weight, reducing handling risk and installation time. This translates to lower lifecycle maintenance and downtime costs, while maintaining robust protection for meters in harsh environments and extending service intervals in the field.
