Eaton CB4033B120208GRA9 Pressure Switch - UL Listed

Single-phase protection with a capacitor trip device is a standout feature that enables rapid, controlled trips during fault events, reducing nuisance trips and protecting critical motors. This translates to lower downtime and more predictable production runs, especially in continuous process lines and HVAC control panels. The three-pole bottom-feed fusible configuration simplifies wiring, reduces panel depth, and speeds installation, helping contractors meet tight commissioning schedules and minimize wiring errors. Ground fault with a control power transformer adds an additional layer of protection, while the optional Ground Fault Relay and Blown Fuse Detection expand future-proofing for evolving safety standards and plant safety policies. The BFD with three indicator lights provides immediate trip status, accelerating fault diagnosis and reducing maintenance cycles. With a 208V system rating and 120V control voltage, this unit supports common industrial voltages while maintaining robust protection across machine centers and switchgear racks. The 4000A amperage rating ensures readiness for high‑current motor feeds, and the UL Listed/NEMA compliant design improves compliance, spares customization, and interoperability with Eaton and third‑party control architectures. Overall, the CB4033B120208GRA9 integrates easily with existing protection schemes while delivering measurable improvements in reliability, safety, and total cost of ownership for panel builders and end users.
