Eaton EIBB3050 Circuit Breaker - Explosionproof

Explosionproof construction is the core feature of the EIBB3050. This design delivers protection against ignition sources in Class I, Division 1 and Zone 1 environments, reducing arc flash risk and meeting stringent hazardous-location codes. The business impact is clear: improved safety, easier regulatory acceptance, and reduced insurance exposure. In practice, electricians install these breakers in oil refineries or chemical plants where uptime matters and space is at a premium, and the EG frame coordinating with bolted covers ensures reliable containment of fault energy. Rated 50 A and configured as a three-pole unit in an EG frame, the EIBB3050 supports clean coordination with downstream protective devices while handling up to 600 Vac. The business impact is improved protection coordination and minimized nuisance tripping, translating to reduced maintenance and downtime. This makes it ideal for main distribution boards and hazardous-location panels in heavy-industry facilities. Enclosure material is copper-free aluminum with bolted/ground joint cover construction, delivering lighter weight without sacrificing strength. The installation advantage is easier handling, fast field assembly, and corrosion resistance in harsh environments. The integrated enclosure-with-breaker approach simplifies retrofits and new-builds, allowing quicker project timelines and consistent performance in demanding settings. Certification and compliance are central to the EIBB3050, with NEC/CEC standards, Class I Division 1, Zone 1, and additional Class II Division 1 and Class III ratings, plus NEMA 3, 3R, 4, 7, 9. The business impact is audit-ready documentation and a smoother approval process from utilities and inspectors. The result is safer operation, easier procurement approvals, and long-term lifecycle reliability across industrial locations. Manufactured to be ready-for-install with an enclosure included and fittings for bolted cover installations, the EIBB3050 also provides compatible dimensions for space planning. The product dimensions (12.53 in depth, 16.53 in height, 9.75 in width) and a 60 lb weight help designers allocate footprint in control rooms and cabinets. In practice, this translates to predictable installation costs and scalable protection for 50 A circuits in hazardous environments.
