FAQs
CB4033B120480RAXCT fits standard bolted switchgear with bottom feed and a three-pole configuration. Verify enclosure compatibility with NEMA ratings (1, 3R, 4, 12) and ensure the space allows for its 17 in L x 32 in H x 40 in W footprint and 415 lb weight. Consider optional Ground Fault Relay or auxiliary provisions to match your protection scheme.
Key specs include a 4000A amperage rating, 480V system voltage, 3-phase operation, 120V control voltage, fusible protection, bottom feed, and a capacitor trip device (SPVR). The unit is UL Listed and designed for use with NEMA 1, 3R, 4, and 12 enclosures, making it suitable for demanding industrial environments.
Yes. The three-pole fusible switch with SPVR provides robust motor protection by coordinating with control circuits at 120V, while handling 480V system voltage. Its bottom-feed configuration and UL/NEMA compliance simplify integration into motor control centers and switchgear, reducing risk of nuisance trips and improving overall system reliability.
The CB4033B120480RAXCT is UL Listed and rated for NEMA 1, NEMA 3R, NEMA 4, and NEMA 12 enclosures. These certifications confirm suitability for both indoor and outdoor/damp environments, while meeting common industrial protection standards for switchgear and control panels.
The solution offers predictable maintenance due to capacitor-trip SPVR and reliable fuse protection, reducing downtime and spare-parts requirements. Eaton provides a 1-year warranty from installation or 18 months from shipment, plus access to specification sheets for easy procurement and standardized maintenance planning, supporting a favorable total cost of ownership in long-running plants.
