Eaton Specification Sheet - CB1633B120208R
High current capability directly translates to reduced circuit failures, enabling 1600A protection without sacrificing response speed or selectivity. This reduces motor stall events, minimizes unplanned downtime, and improves overall line reliability, especially in heavy industry feeders and switchgear assemblies. The 120V control voltage provides seamless integration with standard plant controls and relays, facilitating straightforward wiring and faster commissioning in control panels. The three-pole, three-wire bottom-feed design offers a compact footprint and easier mounting in tight spaces, reducing installation time and labor costs. Fusible protection adds a layer of fault isolation that supports safer maintenance workflows and clearer fault diagnosis during servicing. The SPVR capacitor trip device delivers precise timing and dependable operation for single-phase circuits, improving protection accuracy in dynamic load conditions. Catalog notes indicate optional ground fault relay, blown fuse detection, and auxiliary contact provisions for expanded monitoring and compliance with complex safety schemes.
