Eaton Specification Sheet - CB2533T120480KG14
High-amperage capability, with a 2500A rating, provides reliable fault interruption for three-pole systems. This delivers a measurable business impact: reduced arc exposure, minimized downtime, and improved protection coordination with upstream breakers. Applications include heavy-duty switchgear, motor feeders, and large-scale process lines where uptime and safety are non-negotiable. Top-feed wiring and fuse configuration simplify field wiring and documentation, reducing assembly time and potential miswiring during commissioning. The result is faster installation, fewer wiring errors, and consistent electrical protection across panels. Ideal for control rooms and outdoor installations where rugged performance and straightforward maintenance are critical. UL Listed and NEMA-rated housing support regulatory compliance and environmental readiness. This makes the CB2533T120480KG14 a robust choice for plant floors, outdoor equipment enclosures, and utility-scale equipment. Optional features expand protection schemes without swapping components. Performance benefits include fault detection, better diagnostic data, and easier integration with safety interlocks. Practical use cases span assembly lines, packaging facilities, and energy-intensive plants. Drawing on Eaton's specification sheet and engineering guidance, the CB2533T120480KG14 helps standardize protection across fleets, supports retrofit projects, and aligns with common procurement workflows.

FAQs
CB2533T120480KG14 is engineered for heavy-duty switchgear installations. It delivers three-pole, 3NO-3NC operation with top-feed wiring, 480 V system voltage, and 120 V control power, all housed in a UL Listed package compatible with NEMA 1, 3R, 4, and 12 enclosures. Optional ground fault relay and auxiliary contacts support expanded safety and control schemes.
Using a 2500A amperage rating means the switch can interrupt and withstand large fault currents, reducing the risk of arcing and equipment damage. Designers can specify single- or three-phase protection with fusible elements wired for top-feed configurations, enabling safer startup sequences and improved coordination with upstream breakers and transformers in mission-critical plants.
Yes. The CB2533T120480KG14 is designed for interlock applications in safety-critical lines, featuring an interlock option and ground fault protection. Its top-feed, three-pole configuration supports reliable lockout/tagout sequences, while the 480 V system and 120 V control voltage align with common plant safety standards and Eaton's documented installation practices, plus lifecycle support from qualified technicians.
This switch carries UL Listed certification, signaling conformance with recognized safety standards. Its NEMA ratings cover multiple enclosure environments, including NEMA 1, 3R, 4, and 12. Optional features such as ground fault relay, single-phase protection, and auxiliary contacts further support regulatory compliance, risk reduction, and safe fault signaling across industrial facilities.
Adopting this switch can improve uptime through robust fault protection, reduced wiring errors, and fewer field service calls thanks to clear Eaton documentation and configurable options. Its UL Listed, NEMA-compatible housing minimizes replacement costs after events, while optional features like blown fuse detection enable proactive maintenance, contributing to longer asset life and lower total cost of ownership.
