Eaton Specification Sheet - GUB3177
Copper-free aluminum body provides corrosion resistance and weight advantage, reducing enclosure replacement costs while withstanding aggressive process environments. This translates into lower lifecycle costs and simpler handling during installation in confined spaces, making it ideal for chemical processing and oil & gas facilities. The 17.69 in length/depth and 12x12 in footprint maximize interior space for mounting controls and auxiliary equipment without oversizing the enclosure. The 150 lb weight adds rugged support while still allowing practical handling with standard hoisting methods. NEC/CEC compliance and Class I/II/III ratings ensure regulatory alignment across US and Canada, minimizing risk during audits and simplifying multi-site procurement. Material selection supports longer service life in harsh atmospheres, reducing maintenance frequency and total cost of ownership. Compatibility with Eaton GUB accessories speeds installation and future expansions while maintaining explosion-protected integrity.

FAQs
GUB3177 is designed to align with Eaton Crouse-Hinds GUB equipment housing family and uses standard mounting footprints common to industrial enclosures. The 12x12 inch footprint and 17.69 inch depth provide predictable interior space for controls, while compatible gasket systems and hardware preserve explosion-proof ratings. For best results, use Eaton-specified mounting hardware and accessories to ensure seal integrity and continued compliance in hazardous locations.
GUB3177 carries NEC/CEC compliance with Class I Division 1 and 2, Class II Division 1 and 2, and Class III ratings, suitable for Hazardous/Classified Locations. These ratings require explosion-protected construction and proper installation practices. During setup, verify site classification, select certified fittings for penetrations, and ensure all seals maintain enclosure integrity. UL listings provide assurance for US and Canada installations.
The GUB3177 housing is ideal for industries with demanding hazardous environments, including chemical processing, oil and gas, mining, and water/wastewater applications. Its copper-free aluminum construction, 17.69 in depth, and robust 150 lb framework support power and control enclosures near process equipment, while meeting NEC/CEC standards. It is well-suited for retrofit projects and new installations requiring reliable, explosion-protected protection of electrical infrastructure.
Look for NEC/CEC compliance and UL certifications indicating explosion-proof protection for Class I, II, and III locations. Specifically, confirm Class I Division 1 and 2, Class II Division 1 and 2, and Class III ratings, with US and Canada listings. Ensure the unit carries appropriate UL documentation and that the installation site adheres to the corresponding classification and approved fittings for penetrations and sealing.
The copper-free aluminum construction offers improved corrosion resistance and longer service life, reducing replacement and maintenance costs in harsh environments. Its robust build supports lower downtime and fewer field repairs. ROI benefits come from extended enclosure life, fewer spare parts, and faster installation with standard mounting patterns and Eaton reliability, making it a cost-effective choice for enduring hazardous-location deployments.
