Eaton Specification Sheet - CB4033T1204807
Amperage rating of 4000A provides robust protection for large feeders and motor-start applications, delivering high-current switching with confidence and reducing the risk of nuisance trips. Business impact: improved equipment protection, lower unplanned downtime, and better protection coordination for heavy-duty industrial power systems. Application: suitable for 480 V systems in manufacturing lines and power distribution panels where large fault currents are possible. The 120 V control voltage simplifies integration with standard control circuits and minimizes interlock wiring complexity, enabling faster commissioning. Business impact: streamlined control wiring and reduced installation costs. Application: ideal for retrofit projects in existing Eaton ecosystems or new installations seeking reliable top-feed protection and easy maintenance. The 2 NO-2 NC contact configuration with three poles supports flexible interlocking and selective protection strategies, improving conveyor and pump reliability in demanding environments. Business impact: improved protection selectivity, easier fault isolation, and safer shutdown sequences. Application: three-wire, fusible protection schemes in harsh environments. The NEMA 1, 3R, 4, 12 compatibility combined with UL Listed certification provides broad environmental resilience and code-compliant performance. Business impact: minimized compliance risk, versatile enclosure compatibility, and longer service life for outdoor and harsh indoor settings. Catalog notes offer optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contacts, enabling tailored protection schemes. Application: configure per-specification protection packages for specific plant safety and reliability goals.

FAQs
When installing CB4033T1204807, plan for a top-feed wiring configuration, ensure a three-pole, three-wire setup, and accommodate the 480 V system with a 120 V control circuit. Use fusible protection as specified and consider optional ground fault relay or auxiliary contact provisions to support your protection topology. Proper enclosure selection (UL Listed) and adherence to NEMA ratings will improve reliability.
Yes. The CB4033T1204807 is rated for 480 V systems and carries NEMA compatibility for 1, 3R, 4, and 12 enclosures. This makes it suitable for a wide range of indoor and outdoor applications, from clean rooms to harsher industrial environments, while maintaining consistent protection and safe operation.
This Eaton switch is UL Listed, providing recognized safety certification for industrial equipment. It also supports relevant NEMA enclosure ratings (1, 3R, 4, 12), ensuring resilience in varied environments. These certifications help confirm compliance with electrical codes and reduce risk during audits, commissioning, and routine maintenance.
Charge-before-close ensures the switch makes electrical contact only after preconditions are verified, reducing arcing and mechanical wear during closing. This improves reliability, decreases contact wear, and minimizes the likelihood of false trips in high-current applications, which is especially valuable in large motor starts and heavy feeders common in 480 V networks.
The unit carries Eaton’s warranty policy aligned to installation and shipment timelines. With fusible protection, fuse servicing and spare parts planning should be included in maintenance budgets. Optional provisions (Ground Fault Relay, Blown Fuse Detection, Auxiliary Contacts) can influence preventive maintenance routines and spare-part inventories, so establish a protection strategy that aligns with plant uptime targets.
