Eaton CB1233B120480G7 Bolted pressure contact switch - UL
Part Number: CB1233B120480G7
Quick Summary
The Eaton CB1233B120480G7 bolted pressure contact switch provides high-current protection for industrial switchgear and motor control centers. Many facilities face downtime from ground-fault events or protection misconfigurations, so reliable, easy-to-install protection is essential. This unit ships UL Listed and supports rugged environments, with compatible NEMA ratings for a range of enclosures (NEMA 1, 3R, 4, 12). The design also covers safety and maintenance efficiency, including optional ground fault relays and auxiliary provisions. By combining a three-pole, 1200 A configuration with 480 V system capability and a control power transformer, it streamlines protection schemes, reduces wiring complexity, and improves diagnostic visibility for maintenance teams. This translates to lower risk and faster recovery in the field.

FAQs
For installation, verify bottom feed wiring and fuse configuration, ensure a three-pole, 2NO-2NC arrangement, and select a compatible enclosure that meets NEMA ratings (1, 3R, 4, 12). Confirm control power transformer integration and plan for potential ground fault relay options to maximize protection and diagnostic visibility.
Key ratings include 1200 A amperage, 480 V system voltage, 120 V control voltage, and a 2NO-2NC contact configuration. It uses fusible protection and supports ground fault options with a control power transformer for integrated protection within a three-pole, bottom-fed assembly.
Yes. The unit is designed for 480 V systems and can be paired with optional ground fault relay, along with a control power transformer, to enhance fault detection and protective coordination in plant power distribution schemes.
The CB1233B120480G7 is UL Listed, signaling compliance with recognized safety standards for industrial switching devices. This certification simplifies supplier qualification, helps meet regulatory requirements, and supports safer procurement and installation across industrial facilities.
The three-pole, 1200 A design with fusible protection reduces the number of components and wiring, lowering installation and maintenance time. Optional ground fault and auxiliary provisions improve fault diagnosis, reducing downtime. The UL Listing and robust NEMA-compatible enclosure enhance long-term reliability and total cost of ownership.
