Eaton Specification Sheet - CB1233T120208RA9
The single-phase relay with a capacitor trip device (SPVR) delivers a precise, fast trip sequence, enhancing circuit protection. This architecture minimizes nuisance trips and improves safety margins in motor circuits subject to inrush and fault transients. Ideal for motor control centers and panelboards where predictable response times directly impact uptime. With a 1200A amperage rating and 208V system voltage paired with a 120V control voltage, the CB1233T120208RA9 supports large motors and heavy feeders while keeping control power reliable. This combination reduces the need for upgrades when plant loads change and simplifies protection coordination with downstream devices. Applications include manufacturing lines, pumps, and material handling where high current and robust protection are essential. Top-feed configuration and three-pole, three-wire construction streamline wiring inside enclosures, cutting installation time and potential misconnections. The fusible protection option provides selective protection, allowing fuses to be sized to protect feeders and individual circuits. This setup is well-suited for retrofit projects where existing top-fed panels are in service. NEMA ratings of 1, 3R, 4, and 12, along with UL Listing, give designers confidence in this switch’s performance across ambient conditions and enclosure types. The device supports single-phase protection with BFD indicators and auxiliary contact provisions, simplifying status monitoring and maintenance. These certifications help support compliance programs in food & beverage, water treatment, and general manufacturing. Catalog notes indicate optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions are available, enabling scalable protection architectures. When combined with Eaton switching devices and standard control circuits, the CB1233T120208RA9 fits neatly into existing control schemes. This reduces risk during upgrades and helps ensure consistent protection across new and legacy equipment.

FAQs
CB1233T120208RA9 uses a top-feed configuration with three-pole, three-wire design, simplifying wiring in control panels and switchgear. Ensure enclosure clearance matches the 24x16x28 inch profile and verify available space for the fusible protection option. Check that the panel supports 208 V system power and a 120 V control circuit to maintain reliable protection without wire rewiring.
The capacitor trip device (SPVR) provides a controlled, capacitor-assisted trip sequence that reduces nuisance trips during inrush and transient faults. This leads to faster, more predictable shutdown of problematic feeders, minimizing arc exposure and equipment damage while maintaining safe startup sequences for motors and drives.
Yes, the CB1233T120208RA9 is UL Listed, signaling compliance with recognized safety standards for electrical protection devices. This supports regulatory acceptance in many jurisdictions, simplifies procurement paperwork, and streamlines acceptance testing for panels, switchgear, and industrial automation projects.
This switch is ideal for high-current motor feeders, large panel assemblies, and switchgear in manufacturing and process environments. Its 1200A rating, 208V system compatibility, and optional fault-detection features make it suitable for heavy-duty applications such as conveyors, pumps, and line-start protection schemes.
The device’s robust protection, UL-listed assurance, and optional features like Ground Fault Relay and Blown Fuse Detection reduce maintenance interruptions and unplanned downtime. By simplifying wiring and status monitoring through auxiliary provisions, facilities achieve faster fault diagnosis, lower service costs, and improved equipment uptime over the life of the installation.
