FAQs
This unit uses a JDB frame, three-pole configuration, and a bolted/ground joint/gasketed enclosure. Installers should verify Class I, II, III ratings and area classifications, ensure compatible mounting and cable entries, and refer to IF1616/IF1149/IF1150 installation sheets for gasket kits and flange notes to maintain enclosure integrity in hazardous environments.
Key specs include a 600 Vac voltage rating, 70–250 A amperage range, and a 125 A trip characteristic within a 250 A frame. It is a three-pole device designed for hazardous locations with a copper-free aluminum enclosure, suitable for demanding industrial feeders and control circuits.
Yes. It is certified for Hazardous/Classified Locations with NEC/CEC standards and multiple NEMA ratings (3, 3R, 4, 7, 9, 12). Its explosionproof construction and gasketed enclosure are specifically intended for environments with flammable or explosive atmospheres.
It carries NEC/CEC compliance and Class I, Division 1 and 2, Class II, Division 1 and 2, Class III hazardous ratings. NEMA ratings provide added enclosure versatility, while UL/Canadian certifications are referenced in the datasheets and UL certificate pages for Canada.
The copper-free aluminum enclosure resists corrosion, reducing maintenance needs in aggressive environments. The bolted/ground joint/gasketed cover enables resealing during service, and Eaton’s installation resources (IF1616, SP3D packages) simplify replacements and spare-part management, delivering lower total cost of ownership.
