Eaton Specification Sheet - GUB3190 1 20
Feraloy iron alloy construction provides exceptional strength and abrasion resistance, delivering longer service life and reduced maintenance costs. This translates to fewer unplanned outages and safer cabinet integrity in harsh environments such as chemical plants and mining operations. The top conduit opening design simplifies wiring, accelerates installation, and reduces sealant and fittings expenses, improving project timelines in busy utility spaces. A 3/4 in trade size with a mounting plate for standard meters ensures broad compatibility, enabling rapid retrofits and minimizing spare-part inventories across evolving metering schemes. Certifications for NEC/CEC IEC and hazardous area classifications (Class I, II, III; Divisions 1 and 2) support compliant deployments in oil, gas, and refining contexts. GUB03 basic housing compatibility further enhances upgrade paths without full cabinet replacement.

FAQs
GUB3190 1 20 is a housing with a mounting plate designed for standard meters and intended for use with the GUB03 basic housing. It accepts a 3/4 inch trade-size conduit and provides a top conduit opening to simplify wiring. The external dimensions (12.13 in L, 10.75 in H, 8.31 in W) define the space for meter assemblies and accessories. This enables straightforward retrofit in existing metering panels without full enclosure replacement.
The enclosure is certified for Hazardous/Classified Locations with NEC/CEC IEC standards, including Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III. It carries NEMA ratings 3, 7, 9, 12, which align with common refinery, chemical processing, and mining applications. These certifications streamline regulatory approvals and insurance considerations for equipment in hazardous environments.
Key design features such as the top conduit opening and mounting plate for standard meters reduce wiring complexity and field assembly steps. The rugged Feraloy iron alloy housing provides robust protection, minimizing rework due to environmental exposure. Together, these aspects shorten commissioning timelines and improve overall project efficiency in plants with space constraints and strict safety requirements.
Yes. The product's special features specify availability for use in Group B and C hazardous areas, expanding its applicability beyond common Class I locations. This makes it suitable for specialized services where risk profiles require enhanced enclosure protection, such as certain chemical processing and petrochemical applications, while maintaining compatibility with the GUB03 basic housing for phased upgrades.
The enclosure provides a 12.13 in length/depth, 10.75 in height, and 8.31 in width. It weighs 93 lb. Made from Feraloy iron alloy, it is engineered for durability in harsh environments. The top conduit opening and 3/4 in trade size further define the physical footprint and wiring pathways, supporting reliable meter mounting and service access.
