Eaton CB1233B120208RCT Pressure Contact Switch - UL Listed
Part Number: CB1233B120208RCT
Quick Summary
The Eaton CB1233B120208RCT pressure contact switch is designed to deliver reliable single-phase protection for industrial control panels. Engineers often struggle with nuisance trips and wiring complexity when protecting large feeds, but this device combines a capacitor trip system with a controlled charge-before-close mechanism to improve reliability and coordination. UL Listed certification confirms safety compliance, while NEMA ratings 1, 3R, 4 and 12 extend use across indoor, outdoor, and harsher environments. Designed for retrofit in low-voltage switchgear and motor-control centers, it also supports optional Ground Fault Relay and auxiliary contacts, enabling scalable protection without extensive rewiring and delivering measurable reductions in downtime and maintenance costs.

Eaton Specification Sheet - CB1233B120208RCT
Feature → Business Impact → Application: Bolted pressure contact switch design handles 1200A continuous current, enabling you to consolidate feeders and reduce the need for parallel devices, which lowers panel size and installation complexity. This translates to faster commissioning and improved reliability in motor feeders and main disconnects within switchgear assemblies. Feature → Business Impact → Application: Integrated SPVR capacitor trip device provides a controlled, fast trip sequence that minimizes arc energy and nuisance trips, enhancing safety and uptime in 120V control circuits and 208V systems common to packaging lines and process equipment. Feature → Business Impact → Application: Bottom feed and fusible configuration streamline wiring topology and fault isolation, while optional Ground Fault Relay and auxiliary provisions expand protection schemes to meet evolving plant safety standards in confined spaces and outdoor enclosures. Feature → Business Impact → Application: Compliance-friendly enclosure ratings (NEMA 1, 3R, 4, 12) support both indoor installations and outdoor or washdown environments, reducing the need for accessories and accelerating project timelines in basements, plant floors, and outdoor MCCs. Feature → Business Impact → Application: Compatibility with Kirk provisions, auxiliary contacts, and blown fuse detection enables scalable protection architectures, allowing engineers to tailor protection to specific load profiles, improve selectivity, and simplify maintenance in critical infrastructure. Feature → Business Impact → Application: The 16 in length, 24 in width, 32 in height footprint and 200 lb weight provide a robust, space-conscious solution for retrofit projects and new builds alike, with a one-year warranty (or 18 months from shipment) offering predictable service planning and vendor support for long-term ROI.

FAQs
Installation requires confirming three-pole, bottom-feed configuration and fusible protection. Verify control voltage at 120V and system voltage at 208V, then wire the bottom feed inputs to the main conductors. If a Ground Fault Relay or auxiliary contacts are required, connect them per the Kirk provisions and accessory documentation. Ensure UL Listed compliance and proper enclosure sealing for your application.
The device is rated for 1200A amperage, with a control voltage of 120V and a system voltage of 208V. It is a three-pole, three-wire configuration with fusible protection, suitable for 208V power distribution and 120V control circuits in low-voltage applications.
Yes, CB1233B120208RCT is UL Listed, providing recognized safety compliance in industrial environments. It carries NEMA ratings including 1, 3R, 4, and 12, enabling use in indoor panels, outdoor enclosures, and damp or harsh environments without additional enclosure modifications.
Optional protections include Ground Fault Relay, Blown Fuse Detection, Auxiliary Contact Provisions, and Kirk Provisions. These options enable enhanced fault detection, 3rd-leg monitoring, expanded interlocking capabilities, and easier integration into customized protection schemes for complex loads.
