Eaton CB1233B120480KGR5 Bolted pressure switch - UL Listed
Part Number: CB1233B120480KGR5
Quick Summary
Eaton CB1233B120480KGR5 bolted pressure switch enables reliable trip protection in heavy-duty industrial switchgear. Downtime and nuisance trips erode productivity when protective devices fail to coordinate with feeders and transformers. UL Listed certification confirms safety compliance, while NEMA ratings for enclosure protection (NEMA 1, 3R, 4, 12) support field installation across harsh environments. This solution integrates with existing low-voltage controls and delivers robust three-pole protection, blending reliability with cost-conscious performance for modern power distribution and motor control centers.

FAQs
For installation, ensure bottom-feed configuration matches your enclosure, note the three-pole, 1 NO-1 NC arrangement, and account for the 16 in x 24 in x 32 in footprint with a 200 lb weight. Use the optional ground fault relay and auxiliary contact provisions as needed. UL Listed status supports compliance in standard industrial environments.
The unit provides 1200A amperage with a 120 V control circuit and 480 V system voltage. It is a three-pole, three-wire device with fusible protection and ground fault options. It supports NEMA ratings 1, 3R, 4, and 12, making it compatible with a wide range of industrial switchgear and motor control centers.
Yes. With a three-pole design and 1200A rating, this switch provides robust three-phase protection for heavy-duty feeders and switchgear. Its bottom-feed configuration simplifies integration into existing enclosures, and its SPVR option enhances single-phase protection within a three-pole system.
The product is UL Listed, ensuring compliance with safety standards. It also carries enclosure compatibility across NEMA 1, 3R, 4, and 12 environments. The UPC for reference is 782116956142, and the model is CB1233B120480KGR5.
The combination of robust trip protection (including SPVR and ground fault options), durable enclosure ratings, and clear installation pathways reduces unscheduled downtime and maintenance costs. With a one-year warranty from installation (or 18 months from shipment, whichever comes first), you gain predictable total cost of ownership and faster time to operation.
