Explosionproof construction under the EIB family minimizes ignition risk in hazardous locations, delivering dependable protection for critical feeders. The EG frame, three-pole arrangement, and 30 A rating translate into a robust solution for oil, gas, chemical processing, and heavy equipment enclosures. The 600 Vac maximum voltage rating supports demanding motor and control circuits, reducing nuisance trips and enabling safer shutdowns during faults. In real-world panels, this translates to improved uptime, predictable coordination with upstream protection, and easier calibration during commissioning. Copper-free aluminum enclosure reduces weight and corrosion potential, helping lower installation costs and extend service life in harsh environments. For offshore platforms or chemical plants, this matters because it resists exposure to moisture and chemicals while maintaining thermal performance. Bolted/ground joint enclosure cover construction ensures a sealed, service-friendly interior; technicians experience faster maintenance outages and safer ingress protection. UL hazardous-location certification, NEC/CEC compliance, and NEMA ratings 3-3R-4-7-9 provide regulatory assurance, making it easier to specify and approve in project documentation. Compatibility with Eaton/Cutler-Hammer components supports seamless integration into existing industrial networks and spare parts supply.

FAQs
The EIBA3030 uses a bolted/ground joint enclosure with an EG frame and copper-free aluminum housing, designed for straightforward retrofits. Ensure proper clearance for the 10.47 in depth, 12.47 in height, and 7.65 in width, and mount the unit in panels rated for Class I Division 1/ Zone 1 locations. Follow IF 1501 instructions for wiring and torque specs to maintain UL/NEC compliance.
It is a three-pole circuit breaker rated at 30 A with a 600 Vac maximum voltage. The 600 Vac rating supports motor starters and high-power feeders, while the three-pole configuration provides balanced protection across phases. This combination reduces nuisance trips and improves protective coordination in control cabinets and switchgear.
Yes. The device is certified for hazardous/classified locations with NEC/CEC standards and UL hazardous-location listings. This makes it well-suited for oil, gas, and chemical processing environments where equipment must endure explosive atmospheres while maintaining reliable protection and safe operation.
EIBA3030 supports UL hazardous-location certification for Canada and the US, NEC/CEC compliance, and NEMA ratings 3, 3R, 4, 7, 9. These certifications provide regulatory assurance, simplify project approvals, and help ensure safe operation in harsh industrial environments.
The rugged copper-free aluminum enclosure, lightweight design, and explosionproof construction reduce corrosion risk and maintenance costs while extending service life. Reliable UL/NEC/CEC compliance minimizes compliance-related downtime, and the ease of installation with standard Eaton components lowers spare-parts inventories and downtime during maintenance windows, delivering measurable total cost of ownership benefits.
