Eaton Specification Sheet - AFU0333 50 S752
Feature: Amperage rating of 15A at 600 Vac enables direct integration with standard conveyor motor circuits, eliminating the need for extra contactors in many layouts. Business impact: this reduces panel space, simplifies wiring harness routing, and shortens commissioning time by removing intermediate control stages and potential failure points. Application: ideal for mid-range belt conveyors in mining, chemical processing, and manufacturing environments where reliability and simplicity truly matter. Feature: Contact arrangement includes two normally open and two normally closed contacts, enabling flexible safety logic without additional modules. Business impact: supports redundant stop circuits and configurable interlocks that reduce risk during belt operation and maintenance. Application: suitable for conveyors requiring start/stop interlocks and fail-safe behavior in hazardous zones. Feature: Total operating force is 25 lb, ensuring dependable actuation even with belt tension, grit, or routine dust buildup. Business impact: minimizes nuisance trips, improves line efficiency, and lowers operator variability during manual resets and fault responses. Application: ideal for frequent manual engagement in maintenance or emergency-stop sequences on production lines. Feature: Feraloy iron alloy housing plus Corro-free epoxy powder coat finish delivers excellent corrosion resistance and structural robustness in harsh environments. Business impact: extends service life in humid, dusty, or chemically aggressive environments, reducing maintenance frequency and lifecycle costs. Application: outdoor installations and hazardous facilities across mining, chemical, and food-processing sectors. Feature: IP66 ingress protection, plus NEMA ratings 3, 4, and 9, and NEC/CEC compliance provide comprehensive enclosure and safety certification for global deployments. Business impact: ensures regulatory acceptance, minimizes field failures due to dust or moisture, and supports reliable operation across facilities. Application: conveyors operating in harsh environments with exposure to water spray, dust, or explosive atmospheres. Feature: Three 1-inch hubs and single end left mounting simplify installation and wiring harness routing, reducing field wiring complexity and downtime. Business impact: accelerates retrofit projects and OEM assemblies while maintaining high integrity connections and serviceability. Application: scalable conduit planning for conveyors in hazardous locations across diverse industries.
