Eaton CB2033T120480G14 Bolted Pressure Switch - UL Listed
Part Number: CB2033T120480G14
Quick Summary
The Eaton pringle bolted pressure contact switch provides reliable three-pole protection for industrial switchgear. Engineers frequently struggle to coordinate high-current protection, ground-fault detection, and control-power distribution within compact enclosures. UL Listed with broad NEMA ratings—NEMA 1, 3R, 4, and 12—supports regulatory compliance in harsh industrial environments. Designed for top-feed, fusible configurations and optional auxiliary provisions, it simplifies installation while delivering predictable operation and long service life. This combination across a 480 V system with a 120 V control voltage helps plant teams align protection strategies with existing architectures, reducing integration risk and accelerating commissioning.

FAQs
The CB2033T120480G14 is designed for top-feed installation in protected switchgear enclosures. Ensure proper clearance for three-pole wiring, verify enclosure rating matches NEMA requirements, and align the control-power transformer option with your plant’s 120 V control circuit. Use the optional auxiliary contacts if you need shut-off interlocks or status signaling, and follow Eaton’s mounting templates for safe, code-compliant integration.
This device is rated for 2000A, with a 480 V system voltage and a 120 V control voltage. These ratings support direct protection of high-current feeders and large motors while allowing a compatible control loop. The fusible protection option simplifies coordination with upstream breakers, and the 3NO-3NC configuration enables coordinated trip and close sequences across all three phases.
Yes. The product supports a three-pole, 3 NO-3 NC contact configuration, enabling synchronized switching across phases. Optional auxiliary provisions and contact configurations allow expansion of signaling and interlock capabilities. For advanced diagnostics, consider the available Ground Fault Relay and auxiliary contact options to integrate with your plant’s protection logic.
The CB2033T120480G14 is UL Listed and rated for NEMA 1, 3R, 4, and 12 enclosures. These certifications indicate compliance with safety standards and suitability for diverse environments, from indoor control rooms to damp or hazardous settings. Sizing and installation should follow regulatory guidelines to maintain performance and warranty validity.
High-current protection close to the load reduces downtime due to fault isolation and minimizes the need for external protective devices. The controller transformer and optional fault-detection features simplify diagnostics and preventive maintenance, lowering maintenance costs over the product life. The UL/NEMA compliance also supports long-term reliability in regulated industries.
