Eaton CB4033B120480GA9 Pringle bolted pressure contact switch - UL Listed

Feature → Business Impact → Application: 4000A amperage rating enables safe handling of high-current loads, reducing the risk of arcing and downtime while enabling shorter fuse-protection sequences in motor feeder lines. This translates to improved line continuity for large HVAC, compressor, and conveyor drives in industrial facilities, where uptime directly impacts production. Feature → Three-pole, three-wire configuration with 480 V system voltage ensures precise phase control and robust fault isolation, improving protection accuracy in multi-motor systems and reducing miscoordination events in switchgear assemblies. Application: Use in MCCs and panel boards where dependable three-phase protection is essential. Feature → Bottom feed fuse configuration and bottom feed design simplify installation in tight panels and high-density racks, lowering retrofit time and enabling straightforward maintenance access. Application: Ideal for retrofit projects in aging facilities seeking minimal downtime. Feature → Ground fault with control power transformer option provides enhanced personnel safety and circuit protection, supporting quick fault detection and trip signaling. Application: Critical in environments with elevated ground fault risk, such as dusty or humid industrial settings. Feature → Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions extend configurability, helping contractors tailor protection to specific standards and plant policies. Application: Suitable for OEMs delivering customized MCCs and for end users implementing site-specific protection schemes. Feature → BFD with three normally-on lights (trips switch) provides clear status indication and operational visibility, reducing commissioning time and support calls. Application: Useful during startup and routine testing in data centers or manufacturing lines. Feature → UL Listed certification and NEMA compatibility (1, 3R, 4, 12) support regulatory compliance and installation acceptance in diverse facilities, mitigating risk during audits. Application: Essential for regulated industries and multinational deployments where standardization matters.
