Eaton Specification Sheet - CB4033T120208GR
High amperage rating of 4000A with 208V system support enables reliable switching for large motors and heavy loads, reducing the need for parallel devices and simplifying panel design. This translates to lower installation time and improved energy efficiency in switchgear and distribution centers. The SPVR single-phase relay with capacitor trip device enhances protection selectivity, reducing nuisance trips and arc energy, which helps maintain uptime in critical plant equipment. Top-feed fuse configuration simplifies wiring and wiring density, while Ground Fault with control power transformer provides enhanced fault detection and safer maintenance. Compatibility with NEMA 1, 3R, 4, and 12 enclosures expands installation options across cleanrooms to outdoor-rated spaces, and UL Listed certification supports compliance with global electrical safety standards. Optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contacts offer scalable protection and diagnostics to match evolving protection schemes. Heavyweight construction (about 390 lb) and robust mechanical design enable reliable operation in demanding environments, with installation practices aligned to crane-ready handling and secure mounting. This combination delivers measurable outcomes: reduced downtime, improved safety, easier maintenance, and long-term cost savings for industrial facilities and service teams.
