Eaton Specification Sheet - CB2033T120480GAX7
Feature → Business Impact → Application: Amperage rating of 2000A with 2 NO-2 NC contact configuration enables direct connection to high-current feeders, reducing the need for intermediate devices and improving protection coordination in switchgear and motor control centers. This translates to faster fault isolation and lower downtime in demanding manufacturing environments. Application: main feeders and large motor circuits. Feature → Business Impact → Application: Top feed and fusible configuration simplify wiring and improve fault containment by aligning with common plant protection schemes, enabling quicker maintenance and more reliable startup sequences. Application: data centers, processing plants, and heavy industrial MCCs. Feature → Business Impact → Application: System voltage 480V with a 120V control voltage and a 3-pole, 3-wire design ensures seamless integration into standard low-voltage control power architectures, reducing integration risk and mounting footprint in compact switchgear. Application: cabinet installations and integrated switchgear arrays. Feature → Business Impact → Application: Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Auxiliary Contact Provisions, and Kirk Provisions provide advanced diagnostics and expanded control capability, improving reliability metrics and maintenance planning. Application: preventive maintenance programs and safety-critical protection schemes. Feature → Business Impact → Application: UL Listed and broad NEMA ratings (1, 3R, 4, 12) deliver regulatory compliance and environmental resilience, facilitating easier procurement and fewer compliance deratings. Application: industrial environments with enclosure and corrosion considerations. Feature → Business Impact → Application: Heavyweight, three-pole construction (Three-pole, 180 lb) provides robust mechanical stability in rugged installations, reducing vibration-induced faults and misalignment during service. Application: outdoor and harsh indoor switchgear environments.

FAQs
Plan for a three-pole, three-wire installation with top-feed configuration and sufficient clearance around a 16 x 28 x 24 in enclosure footprint. The unit weighs about 180 lb, so use proper lifting gear and mounting provisions. Verify compatibility with 120 V control power and fusible protection options, and accommodate optional auxiliary/provisions as needed.
It delivers 2000A amperage with 2 normally open and 2 normally closed contacts, enabling direct protection and coordination within switchgear. The three-pole, three-wire design supports reliable switching of large motors, while top-feed and fusible configuration simplify wiring and fault containment during commissioning.
Ground fault protection is available via Ground Fault Relay options, paired with a control transformer to monitor imbalance and trip events. Optional features include Blown Fuse Detection, Single Phase Protection, Auxiliary Contacts, and Kirk Provisions, enhancing diagnostics and safety in critical installations.
This unit is UL Listed and rated for NEMA 1, NEMA 3R, NEMA 4, and NEMA 12 enclosures, delivering robust protection in both indoor and outdoor environments. These certifications support regulatory compliance, safer operation, and simplified procurement for industrial projects.
Leverage the available diagnostics (ground fault, blown fuse detection, auxiliary contacts) to schedule preventive maintenance and reduce unexpected outages. The product warranty covers one year from installation (or 18 months from shipment), and the device is designed for durability in demanding environments, contributing to lower total cost of ownership over time.
