FAQs
CB1233T120208R is a large, heavy IEC/UL-listed switchgear component with dimensions of 16 in depth, 28 in height, and 24 in width, weighing about 180 lb. Plan for secure mounting, adequate clearance, and forklift access. Its top-feed configuration and three-pole design influence enclosure selection, wiring routes, and service access, especially in retrofit projects.
The SPVR feature integrates a capacitor trip device into a single‑phase relay, enabling fast, selective tripping during fault conditions. This reduces nuisance trips while improving coordination with downstream protection. It is particularly beneficial for large feeders and motor-start applications where rapid clearance of faults minimizes downtime and equipment damage.
Yes, CB1233T120208R is rated for a 208 V system voltage and 208 V maximum voltage. It carries UL Listed safety certification and supports NEMA ratings including 1, 3R, 4, and 12. This enables use with a wide range of standard metal enclosures and harsh environments typical in industrial facilities.
Optional Ground Fault Relay and Blown Fuse Detection are available to enhance protection and fault awareness. Kirk Provisions and Auxiliary Contact provisions are also listed as catalog notes, providing versatility for coordination, status indication, and integration with broader control schemes in complex switchgear.
Warranty terms include one year from installation or eighteen months from shipment, whichever comes first, per Eaton policy 25-000. In addition to the warranty, manufacturers’ technical support and documentation (datasheets, catalogs, and specification sheets) are available to assist with installation, commissioning, and ongoing maintenance.
