High-current switching capability: The CB2033B120480KE is rated for 2000 A at 480 V with a 120 V control supply and an integrated power transformer. This reduces the need for separate control power sources, lowering wiring complexity and potential failure points, while enabling reliable fault isolation in main feeders and switchgear assemblies. Applications include MCCs and distribution panels where uptime and safety are paramount. Arc energy reduction relay with matched CTs included: The built-in arc energy reduction relay and coordinated CTs lower incident energy during arcing events, improving operator safety and helping meet arc-flash mitigation practices in modern electrical rooms. Suitable for retrofit projects or new builds where protective coordination is critical. Bottom-feeder fusible three-pole design: The unit’s bottom feed and three-wire configuration streamline wiring layouts and interlocks, reducing installation time and error potential. This configuration supports consistent interconnection with upstream breakers and downstream protection devices in large electrical cabinets. Compact yet robust footprint: With dimensions of 16 in L × 28 in H × 24 in W and a weight of 175 lb, this switch is designed for modular basements of switchgear enclosures and for on-site handling with appropriate lifting gear. This helps ensure proper enclosure fit and serviceability. UL Listed safety certification: The UL listing signals adherence to recognized safety standards, simplifying procurement and compliance documentation for customers operating in North American markets. Compatibility with Eaton Switching Devices fosters a cohesive protection ecosystem for scalable plant-wide protection. Maintenance and lifecycle considerations: The integrated features reduce the number of external components, lowering total cost of ownership and easing routine maintenance, testing, and future protection upgrades within existing Eaton-based electrical architectures.
