FAQs
CB1233B120480KAX uses a bottom-feed, three-pole, three-wire configuration designed for standard switchgear enclosures. It supports fusible protection and interlock options, enabling straightforward installation in NEMA 1, 3R, 4, and 12 environments. When wiring, ensure proper torque on connections up to the 1200A rating and maintain required clearances per Eaton guidelines to preserve trip reliability.
The 1200A rating defines the maximum current the switch can interrupt and carry during normal operation. For fuse selection, size protection to safely interrupt near the device’s trip threshold while considering inrush for motor starts. Review the Eaton specification sheet for recommended fuse types and coordination with 480V systems to optimize protection and minimize nuisance trips.
Yes, CB1233B120480KAX is UL Listed and designed for compatibility with NEMA 1, NEMA 3R, NEMA 4, and NEMA 12 enclosures. This enables safe operation in environments with dust, moisture, and rugged conditions. Always verify enclosure rating on site and follow installation guidelines to maintain UL compliance and protective performance.
Optional features include Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions. These options enable tailored protection schemes, enhanced fault detection, and compatibility with monitoring and control systems, helping you meet specific safety standards and improve maintenance visibility.
Set a preventive maintenance schedule that includes checking mechanical interlock integrity, verifying trip function tests, and inspecting wiring connections for tightness at the 1200A terminals. Record any signs of arcing or overheating, and confirm auxiliary contacts and optional provisions are functioning. Regular inspections help prevent unexpected trips and extend service life in demanding plants.
