Feature: 15A at 600 Vac rating provides headroom for typical conveyor motor control without overloading the contact set. Business Impact: reduces risk of nuisance trips and ensures reliable belt control under peak loads. Application: packaging lines, mining conveyors, and bulk handling systems that require robust power switching. Feature: Two normally open and two normally closed contacts offer flexible interlock and fail-safe control. Business Impact: enables simple safety interlocks and circuit versatility without additional modules. Application: belt-stop interlocks and start/stop sequencing across complex conveyor loops. Feature: IP66 enclosure with hazardous-location approvals (Class II/Division 1 & 2, Class III). Business Impact: superior dust, water, and explosion-protection performance, reducing regulatory exposure. Application: chemical plants, metalworking shops, and grain facilities. Feature: 3 hubs and 1" trade size simplify wiring density and mounting. Business Impact: lowers installation time and improves panel fitment. Application: retrofit projects and new installations on compact control panels. Feature: Feraloy iron alloy construction and 25 lb total operating force ensure rugged actuation. Business Impact: long service life in demanding environments, lowering maintenance costs. Application: high-vibration conveyors and outdoor installations. Feature: Dimensions and weight (12.92 in L, 5.68 in H, 9.5 in W; 21.6 lb with switch). Business Impact: predictable enclosure planning and transportation in retrofits. Application: OEMs and integrators planning space-constrained layouts. Feature: AFU/AFUX series compatibility with UL-certified configurations. Business Impact: minimizes engineering changes and accelerates project timelines. Application: standardization across hazardous-location conveyor control suites.

FAQs

Begin by verifying the three-hub mounting configuration and the single end left orientation. Ensure the control switch is wired to accommodate two normally open and two normally closed contacts, with 1" hubs available for clean cable routing. Secure the unit on a stable surface within the AFU/AFUX family mounting footprint, then route conductors to minimize exposure to dust and moisture. Finally, test the actuating sequence and verify operation under load to confirm belt-stop and start interlocks function as intended.
The switch is rated for 15A at 600 Vac and uses a two normally open, two normally closed contact arrangement. This configuration supports versatile safety interlocks and sequencing for conveyor controls, while maintaining reliable switching under typical industrial loads. The durable Feraloy iron alloy housing provides rugged performance in harsh environments.
Yes. It carries NEC/CEC hazardous-location approvals and area classifications suitable for Class II, Division 1 and Division 2, as well as Class III atmospheres. The enclosure provides IP66 ingress protection, enabling reliable operation in dusty, moist, or corrosive environments common in mining, chemical processing, and heavy manufacturing.
AFU0333 50 is designed as part of the AFU/AFUX explosion-proof line, featuring three hubs and compatible mounting dimensions for straightforward integration. This compatibility simplifies retrofits and new-construction installs, reducing engineering time and ensuring consistent performance across the AFU family.
The rugged Feraloy iron alloy construction and 25 lb total operating force deliver reliable actuation and durability in harsh environments, reducing unplanned downtime. Certifications for hazardous locations plus IP66 protection minimize compliance risk, while the compact footprint helps lower enclosure space requirements, contributing to lower total cost of ownership over the equipment lifecycle.
