Explosionproof design enhances safety and compliance, reducing the risk of arc flash and equipment damage in hazardous locations such as chemical plants and offshore facilities. Business impact: improved worker safety, lower insurance and downtime costs, and easier regulatory audits. Application: protection for feeders and branch circuits in Class I/II/III environments. The amperage range of 15 to 70 A on a 100 A frame, with a 3-pole configuration and voltage rating of 480 Vac / 250 Vdc, offers flexible protection for standard and high-demand circuits. Business impact: streamlined panel design and fewer part substitutions, lowering engineering time and inventory. Application: scalable protection across power distribution trains in industrial plants. Copper-free aluminum enclosure and external epoxy powder coat deliver corrosion resistance and longer service life, especially in corrosive atmospheres. Business impact: reduced maintenance costs and longer replacement intervals. Application: outdoor or damp locations in mining, oil & gas, and chemical processing. Bolted/ground joint/gasketed enclosure with standard breather/drain minimizes ingress, supporting reliable operation with less frequent servicing. Business impact: lower corrective maintenance and higher uptime. Application: rugged environments requiring robust enclosure integrity. Availability of SP3D design packages and installation sheets ensures rapid integration and fewer field modifications. Business impact: faster project execution and reduced commissioning risk. Application: system design and retrofit projects in modern industrial facilities.

FAQs

Yes. It is rated for 480 Vac and uses a 100 A frame with three poles. The device supports 15 to 70 A settings, offering flexible protection for feeders and branch circuits. Installation is straightforward in the EBMB enclosure thanks to a bolted/ground joint/gasketed cover, and its copper-free aluminum construction aids weight reduction and corrosion resistance in harsh environments.
The EBMB S752 S756V WT70HFD34 provides an adjustable amperage range from 15 to 70 A with a fixed trip capability up to 70 A, suitable for protecting feeders and small-to-medium loads. It is a three-pole design rated for 480 Vac / 250 Vdc, ensuring balanced protection across phases and predictable coordination with upstream devices.
This breaker is designed for Hazardous/Classified Locations with NEC/CEC compliance and UL listings. It supports Class I, II, and III environments, including Division 1 and Division 2 ratings, making it suitable for oil/gas, chemical processing, mining, and other high-risk industrial settings.
It carries NEC/CEC standards, NEMA ratings including 3, 3R, 4, 4X, 7, 9, 12, and NEC hazardous area classifications. UL certification for hazardous locations is provided, and the enclosure is copper-free aluminum with an external epoxy powder coat, reinforcing compliance and durability in demanding environments.
Key considerations include using the bolted/ground joint/gasketed enclosure design to minimize moisture ingress, leveraging the standard breather/drain for reliability, and referencing the SP3D Design Package and installation sheets for accurate integration. These features reduce field modifications, shorten commissioning, and lower maintenance costs over the life of the installation.
