Eaton CB1233T120480G7 Pressure switch - UL Listed
Part Number: CB1233T120480G7
Quick Summary
Eaton CB1233T120480G7 pressure switch is a heavy-duty control device for high-current industrial power distribution and motor control. Manufacturers often struggle to coordinate ground fault protection, fuse coordination, and control-transformer integration within 480V systems, leading to longer downtime and complex wiring. UL Listed certification backs safety compliance, while the enclosure flexibility reflected in the NEMA ratings—1, 3R, 4, and 12—extends usable environments from general plant floors to wash-down areas. With a 1200A amperage rating and 120V control voltage, plus a top-feed fusible design, the unit delivers reliable protection and easier maintenance for demanding installations. This combination of rugged performance and configurable protection options supports faster procurement, predictable performance, and compliant operation across switchgear and motor-control applications.

Eaton Specification Sheet - CB1233T120480G7
Feature: The CB1233T120480G7 delivers a 1200A amperage rating with a 480V system voltage, enabling high‑power feeders and large motor loads to be protected by a single device. Business impact: This reduces part count, simplifies electrical diagrams, and lowers lifecycle costs while maintaining robust protection. Application: Ideal for switchgear assemblies, motor control centers (MCCs), and distribution panels in demanding manufacturing environments. Feature: It uses a three‑pole design with 2 NO and 2 NC contacts, providing flexible control logic for start/stop interlocks and signaling. Business impact: Engineers can implement timing, interlocks, and sequence control without adding extra relays, improving reliability and reducing maintenance. Application: Suitable for complex protection schemes in conveyors, presses, and automated lines. Feature: Top-feed fuse configuration and compatibility with optional protection options, including ground fault relay, blown fuse detection, and single‑phase protection. Business impact: Facilitates safer, faster installations and minimizes fault propagation by locating protective devices at the source. Application: Common in panelboards and switchgear where quick fault isolation and easy retrofits matter. Feature: Integrated control power transformer minimizes auxiliary wiring and provides a stable control supply for trip circuits. Business impact: Improves reliability, reduces voltage drop on control circuits, and simplifies retrofits or expansions. Application: Effective in facilities where local control power simplifies safety interlocks and coordination with downstream controls. Feature: UL Listed certification and broad NEMA enclosure ratings (1, 3R, 4, 12) guarantee compliance and adaptability across environments. Business impact: Supports regulatory adherence, reduces risk during audits, and expands installation options in washdown, dusty, or harsh environments. Application: Suitable for industrial plants, chemical processing, metal fabrication, and heavy manufacturing lines.

FAQs
Installers should plan for top-feed wiring and fusible protection, ensure enclosure compatibility with the selected NEMA rating, and confirm the presence of the control power transformer to minimize extra control wiring. Verify that the 2NO-2NC configuration aligns with required interlocks and signaling logic, and consider optional ground fault or auxiliary provisions for enhanced safety and monitoring.
The unit provides 1200A capacity and 480V system voltage with fusible protection, reducing fault energy and aiding rapid isolation. Its 2NO-2NC contacts support robust control logic, while the ground fault capability (optional) and integrated transformer simplify detection, signaling, and safe shutdown sequences across demanding industrial lines, contributing to safer operation and lower downtime.
Large motor feeders, switchgear assemblies, and distribution panels in manufacturing, chemical processing, and heavy industry benefit most. The 1200A rating, 480V system compatibility, and top-feed design streamline protection coordination for MCCs, feeders, and critical line sections, reducing component count and simplifying maintenance while maintaining regulatory compliance.
This switch is UL Listed, providing essential safety certification for electrical equipment. It also supports broad NEMA enclosure ratings—1, 3R, 4, and 12—facilitating use in a range of environments from general plant floors to wash-down areas, and helping with regulatory compliance and risk mitigation across industrial installations.
The CB1233T120480G7 reduces overall part counts and simplifies wiring with an integrated control transformer, which lowers installation time and labor costs. Its high current rating and rugged enclosure versatility minimize downtime and maintenance, delivering long-term reliability and predictable performance across critical power distribution and motor-control applications.
