FAQs
For hazardous-location installations, mount the three-pole breaker in an explosionproof enclosure using the bolted/ground joint/gasketed cover. Ensure proper clearance and ventilation per enclosure ratings and NEC/CEC requirements. The copper-free aluminum enclosure reduces weight while maintaining corrosion resistance, simplifying field retrofits and maintenance in Class I/II environments.
This model is a 3-pole, 70–250 A amperage-rated breaker with a 600 Vac maximum voltage. It uses the JDB frame and supports a 250 A frame size, making it suitable for medium to high current motor and feeder protection in hazardous locations. Verify coordination with downstream devices and ensure compatible accessories per the SP3D package and catalog pages.
Yes. The EBMBG WT250JDB36 carries NEC/CEC certifications for Hazardous/Classified Locations, including Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III, along with compatible NEMA ratings (3, 3R, 4, 7, 9, 12). This supports regulatory compliance across North America and many international sites.
Industries like mining, chemical processing, oil and gas, and offshore facilities benefit most due to harsh environments and strict safety standards. The explosionproof design, robust enclosure, and broad environmental ratings reduce risk, downtime, and maintenance costs while ensuring reliable protection for critical feeders and motor circuits.
Routinely inspect gasket integrity, enclosure seals, and mounting hardware to maintain explosionproof performance. Use the provided installation instructions and UL certification references for periodic checks. Availability of SP3D design packages and catalogs helps with lifecycle planning, spare parts, and easy replacement in maintenance schedules.
