Eaton Specification Sheet - AFU0333 66 S752
Explosion-proof, corrosion-resistant construction is engineered for hazardous environments. Feature → Business Impact → Application: The AFU0333 66 S752 uses a feraloy iron alloy housing with a corro-free epoxy powder coat, delivering robust protection against moisture, dust, and chemical exposure. This reduces maintenance costs and extends service life for belt conveyors in mining, chemical plants, and oil & gas facilities. Application: ideal for harsh production floors where downtime must be minimized and equipment reliability is non-negotiable. Flexible contact arrangement supports two normally open and two normally closed contacts at 15A and 600 Vac, enabling complex safety interlock circuits without additional components. This translates to easier wiring, faster commissioning, and safer shutdown logic in emergency-stop scenarios. Application: suitable for belt-stop interlock networks and safety-rated conveyor control systems. The unit features a double-end, 3-hub design with a 1" trade size, and a total operating force of 50 lb. Feature → Business Impact → Application: quick, secure mounting and reliable actuation reduce misalignment and false trips, cutting maintenance visits and enabling rapid line changes. Application: commonly installed on mid- to high-capacity conveyors in hazardous locations. IP66 ingress protection, NEMA ratings 3, 4, 9, and NEC/CEC compliance provide comprehensive environmental and regulatory safety. Feature → Business Impact → Application: ensures worldwide deployment while meeting strict industrial standards, reducing product-adoption barriers and accelerating project timelines. Application: suitable for chemical processing, mining, and other rugged operations. Corro-free epoxy powder coat finish and the overall rugged build support long service life in aggressive plants. Feature → Business Impact → Application: minimizes corrosion-related faults and repaint maintenance, lowering lifecycle costs. Application: useful for outdoor or splash-prone conveyor lines in refinery or waste-water settings.

FAQs
When installing the AFU0333 66 S752 in hazardous locations, mount it as a double-end unit with three hubs and a 1" trade size. Ensure appropriate clearance for maintenance access, verify the enclosure rating (IP66) against expected exposure, and wire the two normally open and two normally closed contacts to the safety circuit to achieve fail-safe belt stopping. Always follow NEC/CEC guidelines and local codes.
The switch provides two normally open and two normally closed contacts with a 15A amperage rating and a 600 Vac voltage rating. This configuration supports versatile safety interlocks and control logic for conveyor systems, enabling safe belt stop and start sequences without additional components, while meeting industrial electrical standards.
Yes. The AFU0333 66 S752 is designed to integrate with standard safety interlocks used in hazardous-area conveyors. Its multiple contacts and robust enclosure allow wiring into emergency-stop circuits and lockout/tagout schemes, reducing wiring complexity and enabling quick integration with existing safety controllers and PLCs.
This switch carries Hazardous/Classified Locations ratings, NEC/CEC standards, and IP66 ingress protection, along with NEMA ratings 3, 4, and 9. These certifications support safe operation in hazardous environments and help ensure compliance for global installations across mining, chemical, and manufacturing sites.
The corrosion-resistant coating, rugged feraloy iron alloy housing, and explosion-proof construction reduce corrosion-related maintenance and unplanned downtime. The 15A/600 Vac rating and three-hub design simplify installation and circuit wiring, enabling faster changeovers and longer service life, which lowers total cost of ownership and improves plant productivity.
