Eaton CB1233B120208GRAX5 Bolted pressure switch - UL Listed

The three-pole configuration with 1 NO-1 NC contacts provides separate control and signaling paths, enabling safe isolation and straightforward integration into motor control centers. This arrangement minimizes backfeed risk and supports precise startup and shutdown sequences for large motors and feeders in demanding production lines. The bottom feed design reduces wiring complexity inside panels, while the compact footprint helps fit into tighter switchgear enclosures. With fusible protection and an optional SPVR capacitor trip device, it coordinates fast fault clearing with upstream protection to protect downstream equipment. Rugged enclosure ratings thanks to NEMA 1, 3R, 4, and 12 support operation in dusty, wet, or outdoor environments, reducing enclosure modifications and improving lifecycle costs. The 208V system voltage and 120V control voltage align with standard industrial power architectures, simplifying integration with existing controls and soft starters. The device is UL Listed, meeting essential safety requirements for electrical products used in North American facilities. Its three-wire, three-pole design offers robust fault isolation and predictable coordination within switchgear, MCCs, and protection panels. Optional features such as Ground Fault Relay and Blown Fuse Detection provide additional layers of protection and diagnostics, enabling maintenance teams to detect deteriorating fuses or ground faults before they impact production. The SPVR feature enhances voltage coordination by providing a capacitor trip that improves trip timing compared to mechanical relays, reducing wear on breakers and extending service intervals. The product’s size and weight—16 in depth, 24 in width, 32 in height; about 200 lb—are factors in planning crane and rigging during installation, and Eaton's installation notes assist with safe handling. From a business perspective, installing CB1233B120208GRAX5 can lower total cost of ownership by decreasing unplanned outages and shortening downtime during maintenance windows. UL Listing and NEMA ratings help meet plant safety and regulatory requirements with minimal additional accessories. Overall, this switch provides a scalable solution for armored control rooms and industrial power distribution, with optional features enabling tailored protection schemes to meet evolving plant standards.
