Eaton Specification Sheet - GUSC3120 40
Feraloy iron alloy enclosure provides rugged protection against harsh environments. The GUSC3120 40 load center leverages this material to resist impact, heat, and corrosion typically encountered in hazardous locations. This translates to longer service life in chemical plants, refineries, mining operations, and other heavy-industrial settings where safety margins are non-negotiable. One 40A, two-pole breaker in a compact 1-inch trade-size footprint simplifies wiring and panel planning while delivering reliable protection for motor loads and lighting circuits at 240V. The tight profile reduces enclosure space requirements, enabling installation in standard electrical rooms or compact switchgear housings without sacrificing fault protection or future expandability. Field technicians will appreciate fewer adapters and faster commissioning. NEC/CEC compliance plus hazardous-location ratings provide reassurance in regulated environments. Class I Division 1 and Division 2, Class II Division 1 and 2, and Class III are supported, with NEMA ratings of 3, 7, 9, and 12 adding further protection against weather, oils, and corrosive atmospheres. This combination lowers project risk, speeds regulatory approvals, and simplifies ongoing maintenance with clear documentation. Dimensions and weight inform enclosure planning and shipping logistics: 7.75 in length, 7.81 in height, 5.81 in width, and 10.22 lb. A predictable footprint minimizes panel design guesswork, while the 1-inch trade-size and 240 Vac rating align with common electrical distribution practices in industrial facilities. The product's compact form also eases retrofit projects in existing skid-mounted or cabinet-based power systems. Documentation availability, including the GUSC catalog page and specification sheets, speeds engineering reviews and field installation. Compatibility with Eaton's GUSC lineup ensures spare parts consistency and streamlined procurement. With UL certification reports and downloadable datasheets, teams can validate compliance during audits and reduce time-to-commission.
