Eaton Specification Sheet - AFU0333 05 S752
Feature → Business Impact → Application: Explosion-proof construction using Feraloy iron alloy delivers robust mechanical integrity and long-term wear resistance in demanding environments, reducing replacement costs and downtime in mining, oil, and chemical processing. This supports safer operations around moving belts and interlocks, improving worker safety metrics and compliance with hazardous-location standards. Feature → Business Impact → Application: IP66-rated enclosure provides dust and water ingress protection, enabling reliable performance in washdown and dusty plants; this minimizes unscheduled maintenance and extends service intervals in food processing, pharmaceutical, and metal fabrication facilities. Feature → Business Impact → Application: Corro-free epoxy powder coat finish resists corrosion from chemicals and moisture, delivering lower corrosion-related maintenance costs and consistent actuation in marine, offshore, and coastal facilities. Feature → Business Impact → Application: 15A at 600 VAC contact rating with two normally open and two normally closed contacts gives flexible wiring options for safety interlocks, machine guarding, and reset circuits across conveyor lines in heavy industries. Feature → Business Impact → Application: Three hubs and a 1" trade size enable simplified field wiring, faster installation, and easier retrofits in retrofitted conveyors or new line builds within chemical plants, mines, and bulk material handling facilities. Feature → Business Impact → Application: 25 lb total operating force and a 12.92 in length, plus single end right configuration, provide precise actuation without overloading control circuits, supporting reliable fault detection and quick troubleshooting in automated lines. These attributes collectively deliver measurable improvements in uptime, regulatory compliance, and total cost of ownership for industrial automation projects.

FAQs
For safe installation, verify NEC/CEC compliance and ensure the device is rated for Hazardous/Classified Locations. Mount using the 1" trade size and plan wiring across all three hubs. Use the single end right configuration and observe proper torque for the 25 lb total operating force to maintain reliable actuation and signaling.
The unit provides two normally open and two normally closed contacts with a 15A amperage rating at 600 VAC. This configuration supports flexible interlocking and signaling schemes for conveyor safety circuits, enabling safe start/stop control and redundant fault signaling in hazardous environments.
Yes. With IP66 ingress protection, class ratings for hazardous locations (NEC/CEC), and NEMA 3, 4, 9 compatibility, this switch is well-suited for hazardous-duty conveyors in mines, chemical plants, and similar environments where explosion-proof and corrosion-resistant performance are required.
This model meets NEC/CEC standards for hazardous locations, provides Class II Division 1/2 and Class III classifications, and carries NEMA ratings 3, 4, and 9. The IP66 enclosure further confirms its protection against dust and powerful water jets, supporting compliance in regulated industrial sectors.
The corrosion-resistant Corro-free coating, robust Feraloy iron alloy body, and durable epoxy finish reduce maintenance frequency and replacement costs. The device’s reliable actuation (25 lb force) minimizes false trips, contributing to higher uptime and a faster return on investment for automated belt systems in harsh plants.
