Key specs include a 20A amperage rating, 120/240 Vac voltage rating, single-pole configuration, and copper-free aluminum construction. The unit is factory sealed and meets NEC/CEC standards with a Class I, Division 2 hazardous location rating, aligning with industry safety requirements.
Yes. The breaker is rated for Hazardous/Classified Locations with Class I, Division 2 protection per NEC, making it appropriate for environments where flammable or hazardous atmospheres are present. Its sealed design helps maintain performance in demanding facilities.
Plan for a single-pole 20A 120/240 Vac replacement in an Eaton Crouse-Hinds panelboard. Verify dimensions (approximately 1.25 in depth, 6.62 in height, 4.44 in width) and weight (about 1.5 lb). Confirm the UPC and catalog data match your panel requirements before swapping to minimize downtime.
Copper-free aluminum reduces corrosion risk, lowers weight for easier handling, and can decrease lifecycle maintenance costs. In hazardous locations, this translates to improved reliability, fewer replacement cycles, and streamlined spare-part management, contributing to lower total cost of ownership over time.
