Eaton Specification Sheet - CB4033B120480GAR
Feature → Business Impact → Application: The CB4033B120480GAR delivers a 4000A amperage rating at 480V system voltage, enabling protection for heavy-duty feeders and large motors with minimal voltage drop and coordinated trip performance. This translates to reduced arc energy exposure, improved equipment uptime, and lower maintenance costs on critical lines in manufacturing facilities and processing plants. Application-wise, the three-pole, bottom-feed configuration supports compact, bottom-fed installations in rugged switchgear, simplifying installation in constrained spaces while maintaining robust fault protection and clear fault indication. Feature → Business Impact → Application: The unit’s electrical trip with a charge-before-close mechanism improves sequence integrity during shutdowns and startups, reducing the risk of inrush damage and unplanned outages in high-load environments. Feature → Business Impact → Application: Ground fault protection, optional ground fault relay, and the control power transformer arrangement enhance personnel safety and fault discrimination, which is vital in exposed or wet-area installations. Feature → Business Impact → Application: Fusible protection and a bottom feed/fuse configuration provide selective coordination and easy fuse replacement, lowering service time during maintenance windows. Feature → Business Impact → Application: The availability of auxiliary contact provisions and Kirk provisions expands integration with programmable logic controllers and third-party interlocks, enabling seamless automation and enhanced monitoring for plant-wide reliability. Feature → Business Impact → Application: UL Listed certification together with NEMA enclosure compatibility ensures regulatory compliance and dependable performance across harsh environments, critical for audit-ready safety programs and insurance requirements.
