Eaton CB1233T120480G14 Pringle bolted pressure switch - UL
Part Number: CB1233T120480G14
Quick Summary
Eaton pringle bolted pressure contact switch provides reliable motor protection in large switchgear and motor control centers. Engineers often struggle with integrating high-current protection, control power transformers, and ground-fault options within a compact footprint. UL Listed certification, NEMA ratings (NEMA 1, 3R, 4, 12), and fusible protection deliver robust safety and compliance for harsh industrial environments. With a built-in control power transformer and a top-feed design, this switch reduces field assembly time while delivering scalable protection for evolving power networks. For procurement and maintenance teams, the built-in options simplify compliance documentation and serviceability, reducing downtime and total cost of ownership.

FAQs
The CB1233T120480G14 provides a three-pole, 3 NO-3 NC contact configuration with top feed and fusible protection, rated at 1200A and 480V. It supports a 120V control voltage and includes ground fault capability with an integrated control power transformer, making it compatible with a wide range of MCC and switchgear architectures.
The built-in control power transformer reduces the number of external components needed, simplifying wiring diagrams and field assembly. This consolidation lowers installation time, minimizes potential wiring errors, and facilitates quicker fault diagnosis during maintenance windows, improving overall uptime.
Yes. The CB1233T120480G14 carries UL Listed certification and is rated for NEMA 1, 3R, 4, and 12 enclosures, offering protection against dust, moisture, and corrosion in demanding production settings. Fusible protection further enhances system safety and reliability.
Plan for a top-fed, three-wire input with a three-pole configuration in a 16x28x24 inch enclosure. Ensure space for the optional ground fault and auxiliary provisions, and confirm compatibility with kirk provisions if used. The unit weighs about 180 lb, so appropriate mounting hardware and support are essential for safe handling.
Expect reduced downtime due to integrated protection features (ground fault, single-phase protection, blown fuse detection) and faster commissioning with the built-in transformer. The 1200A rating and robust NEMA-rated enclosure improve uptime in high-demand applications, delivering lower total cost of ownership over the equipment life cycle.
