Explosionproof enclosure and copper-free aluminum construction deliver corrosion resistance and ignition-source control, reducing maintenance cycles and extending service life in chemical plants, refineries, and offshore facilities. This translates to lower total cost of ownership and safer operations in hazardous environments. The 60 A, three-pole design paired with a 600 Vac rating enables precise current protection and reliable interruption for feeders and downstream devices, improving system reliability and reducing nuisance tripping in demanding environments. Bolted/ground joint enclosure construction plus an insulated neutral lug simplify field installation, minimize grounding issues, and support cleaner wiring runs during retrofits or new builds. NEC/CEC compliance, UL hazardous-location listings, and NEMA ratings 3, 3R, 4, 7, 9 provide a proven safety envelope, helping procurement meet regulatory requirements with confidence. In practice, this means faster approvals, easier maintenance planning, and safer daily operations across oil & gas, chemical processing, and mining sites. The EG frame compatibility with the EIB series ecosystem adds installation flexibility and stock flexibility for distributors and contractors alike, while the 12.53 in length, 16.53 in height, and 9.75 in width dimensions help with panel layout and enclosure planning.

FAQs
The EIBB3060 S146 is designed for areas classified as Hazardous/Classified Locations and supports NEC/CEC compliance with UL listings for hazardous environments. It uses a copper-free aluminum enclosure, insulated neutral lug, and a bolted/ground joint cover to maintain integrity in volatile conditions. Ideal for oil and gas facilities, chemical plants, and other risk-prone sites where rigorous protection and safe maintenance are essential.
The 60 A current rating ensures appropriate protection for feeders and downstream devices, while the 600 Vac voltage rating supports high-energy systems typical in industrial power distribution. This pairing helps achieve proper protective coordination, minimizes voltage-related nuisance trips, and simplifies breaker coordination with upstream protection in hazardous locations.
Yes. The EIBB3060 S146 uses the EG frame type and is intended for use with compatible EN/IEC enclosure assemblies that accept bolted/ground joint covers. The three-pole configuration and insulated neutral lug further align with common EIB series installations, enabling straightforward retrofits and consistent field installation practices.
This breaker aligns with NEC/CEC standards and UL hazardous-location listings, with NEMA ratings including 3, 3R, 4, 7, and 9. Its area classification is Hazardous/Classified Locations, and the combination of UL certification and these ratings supports regulatory compliance, workplace safety, and reliable performance in challenging environments.
