FAQs
CB1233T120480AX56 is configured for top-feed installation and three-pole operation with 1NO-1NC contacts. Its dimensions (16 in L x 28 in H x 24 in W) and weight (180 lb) support rigid mounting within standard electrical enclosures. Ensure enclosure ratings align with NEMA 1, 3R, 4, and 12 requirements and that mounting hardware accommodates the unit’s weight for secure, vibration-resistant operation.
The switch provides 1200A amperage rating, 480V system voltage, and 120V control voltage. It uses a three-pole configuration with 1 normally open and 1 normally closed contact (1NO-1NC) and employs fusible protection. The device is UL Listed and suitable for high-current switching in demanding industrial environments.
Ground fault protection is not included by default. Catalog notes indicate an optional Ground Fault Relay can be added to enhance fault detection. This option supports safer operation in spaces with sensitive equipment or heightened safety requirements without replacing the base switch.
The product is covered by Eaton’s warranty policy 25-000, offering one year from the date of installation or eighteen months from shipment, whichever comes first. This warranty, combined with UL Listing and Eaton support resources, provides assurance for maintenance, service, and parts availability across a broad range of industrial applications.
Catalog notes indicate options for Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions. These provisions allow you to tailor protection schemes to specific applications, enabling safer operation, easier interlocks, and expanded signaling without changing the core switch body.
