FAQs
Install in a compliant hazardous-location enclosure, ensuring it matches explosion-proof or dust-ignition-proof ratings. Use the 1-1/2 in trade size and two-pole TE B frame, secure the threaded cover, and connect conductors per NEC/CEC wiring rules. Verify the non-interchangeable trip setting remains intact to preserve protective characteristics.
Yes. The unit is listed for NEC/CEC compliance with NEC hazardous ratings for Class I Division 1 & 2, Class II Division 1 & 2, and Class III, along with area classifications for Hazardous/Classified Locations and appropriate NEMA ratings, supporting safe operation in demanding environments.
Yes. The product specifications include a voltage rating of 240 Vac / 125–250 Vdc, a 100 A amperage rating, and a two-pole design, making it suitable for mixed AC/DC protection schemes in hazardous-area panels.
Key differentiators include threaded enclosure cover for robust sealing, copper-free aluminum construction for lighter weight and corrosion resistance, a TE B frame type for standard mounting, and a non-interchangeable trip that preserves defined protection characteristics in hazardous locations.
The unit measures 8.5 in depth, 13.38 in height, and 9.13 in width, weighing 43.92 lb. It is designed for integration with explosion-proof FLB enclosures and aligns with a 1-1/2" trade size for straightforward mounting and field serviceability.
