FAQs
CB1233B120480GA95 is designed for bottom feed in three-pole configurations and fits standard switchgear footprints. Its 16 in length, 24 in width, and 32 in height, along with a 200 lb weight, require a stable mounting surface and appropriate lifting equipment. Ensure control voltage and system voltage compatibility (120V control, 480V system) and verify fusible protection options align with your protective scheme.
The device is rated for 1200A and 480V system voltage, with a 120V control circuit. It features fusible protection and three-pole operation with 1 NO-1 NC contact configuration. For safety and compatibility, ensure the enclosure is appropriate for NEMA-rated environments (NEMA 1, 3R, 4, 12) and that any optional ground fault relay is selected if ground fault protection is required.
Yes. The three-pole, 1200A, 480V rating and fusible protection make it well-suited for three-phase protection in motor control centers and switchgear. The bottom-feed configuration simplifies wiring in MCCs, and the 1 NO-1 NC arrangement supports versatile control schemes. It also provides clear status indication via three normally-on lights when tripped.
This Eaton switch is UL Listed, offering a recognized safety certification for electrical equipment. It is compatible with standard NEMA enclosure ratings, supporting safe operation in industrial environments. For CE or IP certifications, verify with Eaton for customer-specific compliance needs, as product documentation highlights UL Listing and enclosure compatibility as primary compliance points.
The product carries Eaton's warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. Maintenance considerations include verifying ground fault options if installed, inspecting contact wear after high-current switching events, and confirming auxiliary contact provisions align with your remote monitoring needs. The high-current rating and robust enclosure support reduced downtime, predictable service intervals, and improved overall return on investment in demanding industrial environments.
