FAQs
The EIBA3030 S756V is a three-pole, 30 A, 600 Vac breaker designed for EG frame installations with a bolted/ground joint enclosure. Its copper-free aluminum construction and compact dimensions fit typical Eaton/Crouse-Hinds enclosures, enabling straightforward retrofits and new builds while maintaining hazardous-location integrity.
Key specs include a 30 A amperage rating, 600 Vac voltage rating, three-pole configuration, and EG frame type. These features deliver reliable overload and short-circuit protection, with a design oriented toward safe operation in hazardous environments and compatibility with Class I, II, and III installations.
This unit supports NEC/CEC standards and NEMA ratings 3, 3R, 4, 7, 9, along with hazard-class classifications such as Class I Division 1 & 2 and Class I Zone 1 & 2, plus Class II/III considerations. These certifications help ensure safe operation, legal compliance, and smoother audits in regulated facilities.
Choose the bolted/ground joint enclosure configuration for superior sealing and durability in harsh environments. The copper-free aluminum enclosure reduces weight and corrosion risk, while breather and drain features support reliable performance. Also leverage available installation sheets and SP3D design packages to accelerate commissioning and reduce field errors.
While exact figures depend on application, benefits include improved safety and compliance, reduced maintenance and downtime due to robust explosionproof design, and faster engineering and installation through available design resources. Over the life of a hazardous-location panel, these factors translate to lower total cost of ownership and less risk exposure.
