Eaton Specification Sheet - CB1233T120480A
High-current capability translates to fewer parallel devices and reduced panel footprint, delivering measurable efficiency gains on MCCs and main distribution schemes. The 1200 A / 480 V rating supports large motor loads with dependable protection, enabling designers to consolidate switching functions and simplify upstream protection coordination. Top feed fuse configuration reduces wiring complexity and accelerates installation, which lowers commissioning time and labour costs. The three-pole, three-wire arrangement ensures balanced switching and reliability, minimizing phase imbalance and fault propagation in three-phase systems. The electrical trip with charge-before-close mechanism enhances safety by preventing inrush-related disturbances and improving fault isolation, while the three normally-on indicators (BFD) provide quick visual diagnostics without false trips. Optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact Provisions allow tailored protection strategies for critical processes. Enclosure compatibility with NEMA 1, 3R, 4, and 12 expands installation options in harsh environments, improving uptime. A robust 180 lb unit with substantial dimensions supports rugged, long-life service in factories and substations, and Eaton’s one-year warranty (with shipment and installation windows) adds financial protection for maintenance planning. Overall, this switch delivers reliability, safety, and cost predictability across industrial power distribution projects.

FAQs
CB1233T120480A is configured for top-feed installation with a three-pole, three-wire arrangement and fusible protection. It supports optional features such as Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contacts to tailor protection and control. Its dimensions and mounting footprint are compatible with standard low-voltage/distribution enclosures, simplifying retrofit projects and new installations alike.
The switch is rated for 1200 A and 480 V, with a 120 V control circuit. This enables reliable interruption and protection of large motors and feeders while maintaining safe control voltages for operators. The three-pole design ensures balanced switching across phases, reducing failure risk from unbalanced loads and improving overall panel reliability.
Yes. The device is designed for NEMA 1, NEMA 3R, NEMA 4, and NEMA 12 applications, offering versatile protection in both indoor and weather-protected environments. UL Listed certification further confirms compliance with safety standards, making it appropriate for industrial panels, substations, and motor control centers requiring robust protection.
UL Listed certification confirms safety and performance compliance with recognized standards for electrical products used in industrial settings. The NEMA-rated enclosure compatibility expands protection options in the field, ensuring the switch can withstand dust, moisture, and mechanical stress in harsh environments. Together, these certifications help procurement decisions, regulatory audits, and system integrators meet reliability and safety goals.
Maintenance focuses on verifying fusible protection integrity, checking auxiliary contacts, and inspecting the availability of optional features like ground fault and blown-fuse detection. ROI benefits come from reduced downtime, fewer spare parts, and extended life of high-current switching assets due to reliable trip performance and robust enclosure protection. The one-year warranty adds financial protection during the initial service window.
