Eaton Specification Sheet - CB4033B120480GPAXC
Feature → Business Impact → Application: The CB4033B120480GPAXC delivers a 4000A amperage rating at 480 V system voltage, enabling it to serve as a main protection device in large motor circuits. This capability translates to fewer protective violations and reduced downtime during fault conditions, especially in high-load applications such as pump libraries and conveyors in manufacturing lines. Application: used in switchgear and power distribution panels where space, reliability, and interoperability matter. Feature → Business Impact → Application: It employs a single-phase voltage relay with a capacitor trip device (Taylor) and a bottom-feed, fusible configuration, delivering precise trip timing and selective coordination. This minimizes unnecessary trips, improving uptime in critical MCCs and packaging lines. Feature → Business Impact → Application: Ground fault protection with control power transformer and optional ground fault relay support enhances personnel safety and equipment protection, aiding compliance with safety standards in chemical plants and energy facilities. Feature → Business Impact → Application: NEMA ratings up to 4 and 12 provide rugged enclosure protection for dirty or damp environments, reducing enclosure fatigue and maintenance needs in food-and-beverage processing or water treatment facilities. Feature → Business Impact → Application: Optional auxiliary contacts and Kirk provisions improve control flexibility, enabling seamless integration into existing automation schemes and future-proofing for upgrades in large-scale plant retrofits. Feature → Business Impact → Application: The bottom-feed fuse configuration and three-pole, three-wire design simplify installation and wire routing in tight panel spaces, accelerating commissioning and minimizing field rework, which is especially valuable in retrofits and expansion projects. Objective outcomes include improved reliability, reduced maintenance cost, and better regulatory compliance across motor-control centers, switchgear, and panel assemblies.

FAQs
This unit uses bottom feed and a three-pole, three-wire configuration, which streamlines wiring harness routing in existing switchgear. Plan for space to accommodate the 22.5 in depth, 32 in height, and 40 in width footprint, and ensure the enclosure offers NEMA 1, 3R, 4 or 12 protection as required by the site environment. Optional ground fault and auxiliary provisions should be integrated during panel modification to maintain protection coverage.
The capacitor trip device provides a controlled, charge-before-close mechanism that helps prevent premature or nuisance tripping on startup transients. In practice, this improves selectivity in single-phase protection schemes and reduces unplanned outages in motor circuits, aligning with reliable MCC operation and safer panel performance.
Yes. The product is engineered for 480 V system voltage with a separate 120 V control circuit, supporting high-current protection while enabling standard control wiring. This separation enhances safety, simplifies control logic interfacing, and supports integration with existing 120 V control infrastructure in industrial environments.
The device is UL Listed and offers broad NEMA protection ratings (1, 3R, 4, 12), which facilitates compliance with safety and enclosure standards across a range of facilities. Optional ground fault and blown-fuse detection further bolster protection requirements in high-risk settings such as chemical plants and water treatment facilities.
With 4000 A rating and fusible protection, the CB4033B120480GPAXC reduces the risk of nuisance trips and unplanned downtime, improving throughput and uptime in critical lines. Routine inspections of contacts, trip devices, and auxiliary provisions, plus periodic fault-detection checks, help preserve performance and extend asset life, delivering a favorable total cost of ownership over the equipment’s life cycle.
