Eaton CB1633B120480E Pressure Switch - UL Listed
Part Number: CB1633B120480E
Quick Summary
Pressure Switches enable high-current control in switchgear applications, protecting motors and feeders by switching at fault conditions. Engineers frequently wrestle with downtime from miscoordination, arc flash risk, and wiring complexity when protecting critical loads, and field service times often spike during current-switching events. UL Listed protection and built-in arc energy reduction help reduce incident energy, while the control transformer and matched CTs streamline installation and upgrade paths for modern switchgear. As a rugged, UL-listed solution, CB1633B120480E delivers reliable protection for 1600 A systems at 480 V with 120 V control. For buyers prioritizing robust, compliant protection in Eaton-supplied switchgear, this model offers a compact, maintenance-friendly path. This model also supports scalable protection schemes and easier future upgrades.

FAQs
CB1633B120480E is designed for ready integration with three-pole, three-wire, fusible switchgear featuring a bottom-feed configuration. It includes a control power transformer and matched CTs for simplified wiring, UL Listed safety compliance, and Arc Energy Reduction. This combination minimizes panel rework, reduces wiring errors, and accelerates field installation while maintaining proper fault coordination.
Key specifications are 1600 A amperage rating, 480 V voltage rating, 120 V control voltage, fusible protection, bottom feed, and three-pole three-wire configuration with an Arc Energy Reduction Relay. These features translate to robust fault protection, reduced incident energy, and coordinated tripping in large electrical feeds, improving reliability of switchgear assemblies in demanding environments.
Yes. The CB1633B120480E is well-suited for MCCs and distribution panels requiring high-current protection and reliable fault isolation. Its three-pole, three-wire, fusible design, bottom-feed configuration, and integrated control transformer simplify design and installation in these environments, while the Arc Energy Reduction relay enhances safety margins in high-energy switching scenarios.
This product is UL Listed, providing recognized safety compliance for industrial control components. UL Listing supports code compliance in many regions and helps ensure consistent performance in protective switching applications. When selecting switchgear components, UL Listed devices reduce procurement risk and streamline audit processes.
Maintenance benefits include fewer internal wiring connections due to integrated transformer and CTs, plus arc energy reduction reducing incident energy exposure. The combination of high-current rating and durable fusible protection lowers replacement intervals and downtime, delivering a favorable total cost of ownership for facilities with frequent switching operations and demanding reliability requirements.
