FAQs
This unit uses a top feed and fusible configuration with a 1 NO-1 NC contact setup, designed for three-pole operation in industrial panels. Plan for mounting in two- or three-bay enclosures and ensure compatibility with 480V systems and a 120V control circuit. Optional features like Ground Fault Relay and auxiliary contacts are available to tailor protection schemes.
The 1 NO-1 NC arrangement allows both normally open and normally closed monitoring within the same device, enabling flexible interlocking with relays and contactors. This supports safer motor control and fault detection, while keeping wiring straightforward and routing predictable in complex panel layouts.
Yes. The switch is rated for a 480V system and a separate 120V control circuit, with a 1200A amperage rating and a top-feed configuration. This combination is common in heavy-duty power distribution and motor control centers, simplifying integration with existing 480V equipment and control logic.
The CB1233T12048056 is UL Listed and supports NEMA ratings 1, 3R, 4, and 12, enabling use in a range of indoor and outdoor, dry, damp, and challenging environments. This combination helps meet safety and reliability requirements in regulated industrial facilities.
Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, and Auxiliary Contact Provisions improve fault detection and diagnostics, reducing downtime and extending device life. The included warranty and Eaton’s support ecosystem help justify lifecycle costs through fewer outages and faster serviceability.
