FAQs
Installation should follow the top-feed fuse configuration and three-pole wiring layout specified by Eaton. Ensure the enclosure provides the compatible NEMA rating (1, 3R, 4, 12), allow clearance for the 180 lb unit, and connect the control transformer as indicated. Use appropriate mounting brackets and verify grounding per site standards to maintain safe operation.
This switch is rated for 1200 A, with a system voltage of 208 V and a control voltage of 120 V. It employs fusible protection and is a three-pole, three-wire device with top-feed configuration, designed for rugged industrial use and compatible with UL safety standards and NEMA-rated enclosures.
Yes. Catalog notes indicate that an optional Ground Fault Relay is available, along with features like Blown Fuse Detection and Auxiliary Contacts. Integration supports enhanced fault detection and faster isolation, improving personnel safety and system reliability in critical power distribution applications.
The CB1233T120208G carries UL Listed certification and is compatible with multiple NEMA ratings, including NEMA 1, 3R, 4, and 12. This combination supports regulatory compliance, safer installation in varied environments, and easier passing of safety inspections during audits or retrofits.
