Eaton CB1633B120208AXCT Bolted Pressure Switch - UL Listed
Part Number: CB1633B120208AXCT
Quick Summary
Eaton CB1633B120208AXCT is a bolted pressure switch used for three-pole protection in industrial switchgear. Facilities teams often struggle with nuisance trips and coordination between devices in 208V systems. UL Listed certification supports safety compliance, while the unit’s rugged, NEMA-rated enclosure options tolerate harsh plant environments. The design includes a charge-before-close mechanism and a 1600A fault rating, with 208V system voltage and 120V control to fit standard control schematics. This combination delivers robust protection, reduces unplanned downtime, and lowers lifecycle costs for panel builders and maintenance teams.

FAQs
Begin by confirming exact ratings (1600A, 208V system, 120V control) and ensuring enclosure compatibility (NEMA 1, 3R, 4, 12). Mount the unit in a bottom-fed position per catalog notes, wire the three poles in a three-wire arrangement, and connect to the control transformer if used. Verify ground fault options are wired correctly and document auxiliary contacts for signaling.
The switch is rated for 1600A with a 208V system voltage and 120V control voltage, featuring fusible protection and a three-pole configuration. It supports bottom feed and is UL Listed. The NEMA-rated enclosure options offer suitability across a range of industrial environments, aiding reliability in large motor feeders and panel assemblies.
Yes. This unit is designed for large-motor feeders and distribution panels, providing robust protection with a charge-before-close mechanism. Its 208V system compatibility and 120V control voltage streamline integration with standard plant controls, while optional features extend protection signaling and remote monitoring for critical manufacturing processes.
CB1633B120208AXCT is UL Listed, ensuring compliance with safety standards for low-voltage protective devices. It also carries NEMA enclosure ratings (1, 3R, 4, 12), which guide where the switch can be installed in tougher industrial environments and how it should be mounted within switchgear and MCCs.
Consider the one-year Eaton warranty from installation or 18 months from shipment, whichever comes first, and plan for routine inspections of fusible protection and contact integrity. The optional Ground Fault Relay, blown fuse detection, and auxiliary contacts support predictive maintenance and faster fault diagnostics, reducing downtime and extending panel lifecycle.
