Eaton Specification Sheet - GUSC3110 40 GB
Explosion-proof construction for hazardous locations in Group B environments directly reduces ignition risk and helps meet stringent safety standards, lowering risk-related downtime and insurance costs while enabling compliant power distribution for critical equipment. The result is improved site safety and predictable maintenance planning, with a clear path to scalable protection as plant loads rise. This unit’s 40 A, 240 V single-pole design provides targeted branch-circuit protection for instrumentation and small-motor loads, promoting dependable operation and easier commissioning in confined spaces or harsh atmospheres. Built with Feraloy iron alloy, the enclosure resists corrosion and thermal stress, extending service life in outdoor or dirty environments and reducing replacement frequency. NEC/CEC compliance and NEMA ratings 3, 7, 9, 12 simplify regulatory audits and procurement alike, while the Group B rating offers appropriate trip characteristics for hazardous locations. Documentation such as spec sheets and catalogs supports fast engineering decisions and smoother retrofits. With one breaker per unit, installation is straightforward, reducing wiring complexity and enabling quick expansion by adding additional load centers from the same GUSC family. The product’s 1" trade size and 7.75 in depth fit common electrical distributions, allowing easier cabinet integration and compatible conduit routing. Overall, the GUSC3110 40 GB delivers consistent protection, operational efficiency, and a lower total cost of ownership for industrial facilities requiring explosion-proof protection and hazardous-location compliance.
