FAQs
When installing the CB1234T120480C, ensure sufficient enclosure space for its 16 in length, 24 in width, and 28 in height. Plan for top-feed wiring and secure mounting to support up to 180 lb. Verify clearance for the control power transformer and CTs, and confirm compatibility with existing protection devices and wiring practices in your MCC or valve area.
The switch is designed for 1200A current at 480V in a three-pole, three-wire setup with fusible protection. It uses a control voltage of 120V and includes a control power transformer to drive control circuits. This configuration enables clean interlocking, safe fault isolation, and straightforward integration into large power distribution and motor-control applications.
The unit includes matched CTs and an AFGF relay for coordinated protection, streamlining integration with compatible Eaton components. Note that CTs for neutral-neutral are not included, so verify your current CT strategy and coordinate with your existing protective scheme to ensure proper current sensing and selective tripping.
The CB1234T120480C carries UL Listed certification, confirming adherence to recognized safety standards for industrial control equipment. This certification supports regulatory compliance and reduces risk during audits. For additional compliance needs, map the device to your NEC/IEEE requirements and ensure compatibility with your site’s safety program and maintenance practices.
Deployment can lower maintenance downtime through improved protection coordination and fewer mis-wiring incidents, thanks to integrated CTs and a control transformer. The robust 1200A/480V ratings reduce fuse replacements and unplanned outages, while faster commissioning lowers labor costs during initial installation and future upgrades. This translates to lower total cost of ownership over the system’s life.
