Selling Policy 25-000 - Distribution and Control Products and Services
3000A amperage rating reduces the need for multiple devices in high-current feeder paths, cutting hardware counts and simplifying protection coordination. This translates to cost savings, faster panel assembly, and improved fault isolation in heavy machinery and large motors. 1NO-1NC contact configuration enables flexible control logic and safer interlocking. This configuration supports both signaling and safety interlocks within a single device, ideal for motor starters and power distribution panels. Three poles with top-feed wiring and fusible protection deliver reliable protective coordination and streamlined installation. The top-feed approach reduces wiring complexity in compact switchgear and simplifies field termination in retrofit projects. UL Listed certification along with NEMA 1, 3R, 4, 12 ratings provide clear guidance for indoor and outdoor safety requirements and rugged environments. This ensures compliance during audits and reduces risk of nonconformance in industrial facilities. Catalog notes indicate optional ground fault relay, blown fuse detection, and auxiliary contact provisions are available to enhance diagnostics and safety. Incorporating these options supports predictive maintenance and faster fault diagnosis, delivering measurable uptime improvements in continuous-process environments. Backed by Eaton's warranty policy and specification sheets, the CB3033T120480K5 supports consistent sourcing and standardized maintenance procedures. Its documented compatibility with Eaton switching devices simplifies inventory management and ensures technicians encounter familiar hardware across projects.
