Quick Summary

The Eaton pringle bolted pressure contact switch provides high-current protection in switchgear and motor control centers. Engineers often contend with nuisance trips, fuse coordination challenges, and limited space in critical installations. UL Listed certification underpins safety, while the unit’s 480 V system voltage and three-pole design align with NEMA-rated enclosures (NEMA 1, 3R, 4, 12). Designed for practical installation and long service life, it complements Eaton switching devices and low-voltage power distribution solutions. By supporting SPVR and optional ground-fault features, it helps reduce downtime and simplify protection schemes across industrial facilities. Bottom-feed, fusible protection in a three-wire, three-pole package provides robust, scalable protection.

FAQs

CB2033B120480GRA9 uses a bottom feed, three-pole configuration with fusible protection. Verify enclosure compatibility (NEMA ratings), ensure all control wiring is rated for 120 V, and confirm space for a heavy 190 lb unit. Follow Eaton installation guidelines to prevent miswiring and to ensure proper trip sequencing with SPVR options.
Key specs include a 2000 A amperage rating, 480 V system voltage, and 120 V control voltage. The device is three-pole with three wires and supports fusible protection. Certification includes UL Listed, with NEMA compatibility across 1, 3R, 4, and 12 enclosures, suitable for robust industrial environments.
Yes, the unit is a three-pole, three-wire switch designed for three-phase protection. It also supports single-phase protection configurations via optional accessories (e.g., SPVR/CAPACITOR TRIP options) when integrated into larger protection schemes, making it versatile for switchgear, MCCs, and feeders in industrial plants.
The CB2033B120480GRA9 is UL Listed, providing recognized safety certification for electrical protection devices. It also carries protection compatibility with NEMA-rated enclosures (1, 3R, 4, 12) for deployment in varied environments, plus available optional features that align with industry protection practices.
Expected benefits include reduced downtime due to reliable tripping and improved fault diagnosis with BFD indicators. Optional ground-fault and fuse-detection features cut maintenance time by enabling faster fault isolation. While ROI depends on site-specific load profiles, the combination of high current capacity, simplified installation, and certified safety typically yields lower operating costs over the device lifecycle.
