FAQs
The CB2033B120480E is designed for bottom-feed wiring with a three-pole, three-wire configuration. Ensure the enclosure supports 16 in length, 28 in height, and 24 in width as specified, and verify that the mounting footprint aligns with your switchgear panel. Plan for 120 V control wiring and route CTs in close proximity to minimize signal interference. This configuration simplifies wiring in control panels and MCCs while ensuring safe, robust operation.
Key specs include a 2000A amperage rating, 480V voltage rating, and 120V control voltage, along with fusible protection. These enable reliable protection for large motors and feeders, improve coordination with upstream protection, and reduce fault energy when a fault occurs. Integration with matched CTs and the Arc Energy Reduction Relay further enhances safety and reduces downtime due to nuisance trips.
Yes. The CB2033B120480E is UL Listed, indicating compliance with recognized safety standards for electrical protective devices. This certification supports procurement decisions in regulated facilities and helps ensure safe operation within 480 V industrial power systems. Always verify that the specific installation adheres to local electrical codes and your site’s safety procedures.
The CB2033B120480E is designed to operate with matched current transformers (CTs) and Eaton protection relays, including the Arc Energy Reduction Relay. This compatibility ensures coordinated protection, accurate fault energy measurement, and consistent operation across the protection scheme. Confirm CT ratio and wiring polarity during installation to maximize performance and safety.
With a 2000A rating and UL-listed safety, the switch reduces downtime from arcing and nuisance trips, lowering maintenance costs and unplanned outages. The integrated control transformer and robust construction support long service life in harsh industrial environments. A planned maintenance schedule focusing on insulation integrity, terminal connections, and CT wiring will maximize reliability and long-term return on investment.
