FAQs

CB3033B120480GRAX5 uses a bottom-feed configuration designed for straightforward wiring into bottom-entry switchgear. Ensure the enclosure supports three-pole, 480 V circuits and that the mounting pattern aligns with the provided dimensions. Verify terminal torque and clearances, then integrate SPVR or ground-fault options if your protection strategy requires selective tripping and fault detection.
The device is rated for 480 V system voltage with a 3000 A amperage rating and a 1 NO-1 NC contact configuration, offering robust protection for large three-phase feeders. Its fusible protection and bottom-feed design simplify integration into high-demand plants, while UL Listing and broad NEMA ratings ensure enclosure compatibility and regulatory compliance.
CB3033B120480GRAX5 carries UL Listed certification and is compatible with NEMA 1, NEMA 3R, NEMA 4, and NEMA 12 enclosures. These certifications and ratings matter because they confirm safety, reliability, and suitability for diverse environments—from clean rooms to harsh industrial spaces—while supporting compliant, risk-managed installations.
Yes. The catalog notes indicate optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contacts are AVAILABLE. These options enable a scalable protection strategy, allow selective tripping, and enhance fault detection without replacing the main switch, reducing downtime and maintenance costs.
With a 1 year warranty from installation or 18 months from shipment, CB3033B120480GRAX5 offers predictable lifecycle costs. Its high current rating, robust enclosure compatibility, and optional SPVR/ground-fault features reduce unplanned outages, lowering maintenance labor, downtime penalties, and associated energy waste, delivering a favorable return on investment over the asset’s life.
