FAQs
Install the CB3033B120480GAR using its bottom-feed configuration, ensuring correct alignment with the panel’s bus bars and mounting studs. Verify three-pole wiring, fuse configuration, and that the control circuit is rated for 120 V. Use Kirk provisions and available auxiliary contact provisions if your system requires interlocking or remote signaling. Follow OEM installation instructions for safe operation.
The switch handles up to 3000A with a 480 V system voltage and a 120 V control voltage. It is fusible and designed for NEMA 1, 3R, 4, 12 enclosure environments. This combination supports reliable trip protection, coordinate with downstream devices, and maintain system integrity during faults while supporting bottom-feed installation.
Yes. With a 3000A amperage rating and 480V system voltage, CB3033B120480GAR is well suited for main protection in switchgear and large distribution panels. Its fusible protection and three-pole design enable robust fault handling, while UL Listed certification helps satisfy regulatory and safety requirements for industrial facilities.
This Eaton model is UL Listed, which confirms conformance to recognized safety standards. It also supports NEMA-rated enclosures including 1, 3R, 4, and 12 environments. Optional ground fault and auxiliary provisions enhance compliance with protective-relay schemes and interlock requirements in industrial spaces.
The unit’s solid build, UL Listed status, and 1-year warranty (plus the option for extended terms) reduce risk and downtime. Its diagnostic features (three normally off lights for fault indication) simplify maintenance planning, enabling faster fault isolation, informed spare-part decisions, and a favorable total cost of ownership over the equipment lifecycle.
