Eaton CB4033B120208GAX Bolted Pressure Switch - UL Listed

Feature → Business Impact → Application: The CB4033B120208GAX delivers a 4000 A amperage rating, enabling reliable high-current protection for demanding motor and line-stop applications. This capability reduces device stacking, minimizes installation footprint, and shortens engineering time while improving fault isolation speed, leading to measurable downtime reductions in production lines. In switchgear, motor control centers, and main distribution panels, the Eaton bolted pressure contact switch supports clean, deliberate trips and quick resets, aligning with safety standards and equipment lifecycles. The inclusion of bottom-feed, fusible protection further contributes to safer, more maintainable architectures. Bottom feed configuration with fuse protection and ground fault integration simplifies wiring, improves traceability, and enhances fault visibility. Ground fault with control power transformer improves selective tripping and nuisance-trip mitigation, translating to fewer unplanned outages and better protection coordination in 208V and 120V feeds. It's ideal for new builds and retrofit projects where reliable by-design protection, straightforward installation, and long-term maintenance planning are critical. Operators benefit from reduced diagnostic time thanks to clear fault indicators and standardised wiring schemes. Three-pole, three-wire design provides balanced protection across all phases, ensuring consistent arc-quenching characteristics and reduced voltage imbalances. The charge-before-close mechanism improves operator safety and reduces contact wear during switching transients, enhancing lifecycle costs for critical circuits. The NEMA ratings extend deployment from clean indoor cabinets to harsh environments, while the 208V system voltage and 120V control voltage align with common industrial power architectures, enabling straightforward integration with existing equipment. Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions give engineers flexibility to tailor protection schemes without expensive retrofits. The UL Listed certification reinforces compliance for electrical safety programs, while induction-free configuration and ground fault options support quick commissioning and safer maintenance in busy facilities. With compatibility notes and standard adapters, this switch integrates with conventional panel designs and reduces total cost of ownership through longer intervals between maintenance and fewer spare-part requirements.
