FAQs
The CB2533B120480G7 uses a bottom-feed configuration with 3 wires and a 2NO-2NC contact arrangement, designed for three-pole, three-wire systems. Wire the three power lines to the bottom-fed terminals and connect the control circuit to the 120 V control transformer. If your panel supports ground fault protection, you can integrate an optional relay to monitor fault conditions without additional control wiring. This setup reduces wiring complexity and speeds up commissioning in new installations or retrofits.
The device delivers 2500A amperage rating with 480V system voltage and a 120V control voltage. It supports fusible protection and is suitable for NEMA-rated environments (1, 3R, 4, 12). The unit is UL Listed and offers 2NO-2NC contact configuration, making it a robust choice for high-current motor feeders and switchgear in industrial settings.
Yes. The three-pole, bottom-feed design with a bottom fuse configuration is well-suited for large-motor protection and high-current feeders. The integrated control transformer simplifies control wiring, while the 2500A rating supports demanding motor applications. Its UL Listed certification and broad NEMA compatibility ensure reliable performance in manufacturing and processing facilities.
The CB2533B120480G7 is UL Listed and compatible with multiple NEMA configurations (1, 3R, 4, 12). UL Listing verifies safety and reliability for industrial use, while NEMA ratings indicate enclosure suitability for various environments, from indoor panels to outdoor or wash-down areas. These certifications help ensure regulatory compliance and reduce risk during audits and inspections.
Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever occurs first. For maintenance, rely on standard protection device diagnostics and inspection routines; optional ground fault and fuse-detection features can reduce downtime by enabling proactive replacement. The product’s robustness, combined with UL/NEMA certifications and integrated transformer, typically delivers lower total cost of ownership through fewer components and faster serviceability.
