Eaton CB4033T120480GPARC Bolted Pressure Switch - UL Listed
Part Number: CB4033T120480GPARC
Quick Summary
The Eaton pringle bolted pressure contact switch protects large motors in industrial panels with a capacitor trip. Users struggle with reliable high-current protection, ground fault handling, and integrating top-feed configurations across 480 V systems. UL Listed protection, broad NEMA compatibility (1/3R/4/12), and optional ground fault or fuse-detection features help ensure code compliance and uptime. In addition, it offers a 4000 A amperage rating, 120 V control voltage, and 480 V system voltage with a top-feed fuse arrangement for straightforward wiring. Designed for three-pole operation in rugged industrial environments, it supports optional ground fault relay, blown fuse detection, auxiliary contacts, and Kirk provisions to fit complex protection schemes.

Eaton Specification Sheet - CB4033T120480GPARC
Feature: Three-pole, top-feed bolted switch design delivers high-current reliability for large motors. Business Impact: Reduces wiring complexity while providing robust protection up to 4000 A, enhancing overall plant reliability. Application: Ideal for motor control centers and switchgear in manufacturing and process environments. The secondary benefit is a compact footprint that simplifies cabinet layouts and reduces installation time. Feature → Business Impact → Application. Feature: Capacitor trip device (Taylor) enables fast, selective tripping. Business Impact: Minimizes nuisance trips and enables rapid fault isolation to protect downstream equipment. Application: Critical for heavy-duty drives and high-energy applications where downtime costs are significant. Feature: Ground fault with control power transformer adds earth-fault protection. Business Impact: Improves personnel safety and reduces unplanned outages by detecting leakage paths. Application: Plant-wide protection in areas with stringent safety requirements. Feature: Optional Ground Fault Relay, Blown Fuse Detection, Auxiliary Contacts, and Kirk Provisions extend protection coverage. Business Impact: Enables retrofit paths and tailored protection schemes without replacing entire switchgear. Application: Upgrading legacy systems and integrating with modern control logic. Feature: NEMA-rated compatibility and UL Listed certification provide ready-made compliance. Business Impact: Accelerates approval in regulated environments and supports enclosure matching. Application: Industrial control panels in harsh environments requiring dependable IP-appropriate protection. Feature: Large dimensions and mass (17 in depth, 28 in height, 40 in width; ~390 lb) improve mechanical robustness for fixed installations. Business Impact: Reduces movement risk during maintenance and ensures stable operation in vibration-prone settings. Application: Heavy industrial installations where mechanical stability is critical.
