Eaton Specification Sheet - CB1233T120480RARCT
High-current capacity and fusible protection deliver robust feeder protection for demanding applications. The CB1233T120480RARCT supports up to 1200A at 480V with fusible protection, reducing the risk of arcing and equipment damage while improving fault-handling reliability. This makes it suitable for motor control centers, large switchgear sections, and critical feeder lines in manufacturing plants where uptime matters. Capacitor Trip Device (SPVR) delivers a controlled, pre-charged trip action for reliable shutdown during faults, improving coordination with capacitor banks and reducing post-trip transients that can affect downstream equipment. Top feed fuse configuration simplifies wiring and reduces enclosure depth for retrofit projects, while optional Ground Fault Relay and Blown Fuse Detection provide continuous protection and fault visibility, minimizing downtime during faults or fuse failures. Rugged enclosure compatibility with NEMA ratings 1, 3R, 4, 12 supports operation in wet, dusty, or harsh environments, and UL Listed certification confirms compliance with safety standards. With a 120V control and 480V system support, it integrates smoothly with common Eaton control gear, enabling straightforward installation and scalable protection across plant networks.

FAQs
Install the CB1233T120480RARCT using the top-feed inputs as specified by the Eaton installation guide. Ensure proper alignment of the three-pole connections, verify proper cable sizing for 1200A service, and secure all terminations to minimize loose connections that can cause heat buildup. Use the optional ground fault or auxiliary provisions only if your protection scheme requires them, and confirm enclosure compatibility with your facility's NEMA environment.
Yes. This switch is designed for 480V system voltage while using a 120V control circuit. It is a three-pole, three-wire configuration with fusible protection, enabling straightforward integration with standard low-voltage control gear and high-voltage feeders commonly found in industrial plants and motor control centers.
The CB1233T120480RARCT carries UL Listed certification, indicating compliance with electrical safety standards. It also supports multiple NEMA enclosure ratings (1, 3R, 4, 12), ensuring compatibility with a range of environmental conditions from clean rooms to damp or dusty industrial spaces. Optional features include Ground Fault Relay and Blown Fuse Detection to aid regulatory and safety requirements.
SPVR devices require periodic checks of capacitor health, mechanical trip alignment, and control wiring integrity. Schedule regular inspection intervals per Eaton’s maintenance guidance, monitor for nuisance trips, and replace any degraded capacitors promptly to maintain fast, reliable trip performance and prevent unintended outages in critical feeders.
ROI is driven by reduced downtime from reliable trips, fewer nuisance trips, and improved fault isolation. The 1200A capacity supports larger feeders, potentially delaying costly upgrades, while top-feed wiring and modular options shorten installation time. Coupled with UL Listed safety compliance and NEMA-rated ruggedness, facilities gain safer operations, fewer maintenance events, and longer equipment life for high-demand environments.
