Eaton Specification Sheet - CB2033B120208R
High current protection with 2000 A service and 208 V system voltage enables reliable handling of large motor loads in switchgear and control panels. Business impact: reduces the risk of catastrophic failure and unplanned downtime, improving plant availability. Application: ideal for motor control centers and heavy-duty feeders where robust protection is required. Integral SPVR capacitor trip device provides coordinated, fast interruption, cutting nuisance trips and extending component life by ensuring proper timing during faults. Application: minimizes wear on relays and contactors while maintaining safe shutdown sequences. Three-pole, bottom feed, fusible configuration simplifies panel wiring and enclosure layout, enabling compact installations in cramped switchgear. Business impact: saves assembly time and reduces cabinet depth. Application: suitable for bottom-fed panels in plant power distribution. Optional features such as Ground Fault Relay, Blown Fuse Detection, Auxiliary Contacts, Kirk Provisions, and Additional Provisions enhance protection, diagnostics, and expandability. Business impact: lowers maintenance costs and speeds fault isolation, supporting predictive maintenance programs. Application: retrofit and new builds requiring scalable protection strategies. UL Listed certification supports compliance and traceability, while NEMA ratings broaden enclosure compatibility across a wide range of environments. The combination of SPVR, fusible protection, and heavy‑duty construction delivers measurable efficiency gains, safer operation, and a clear return on investment for industrial automation projects.
