High-current capability: The CB2033B120480GAX7 is rated for 2000A with a three-pole, 2NO-2NC contact configuration. Business impact includes reducing the need for multiple protective devices and enabling more compact, cost-effective switchgear layouts. Application: motor control centers and large feeders where reliable, single-device protection improves up-time and simplifies panel design. This also supports streamlined spare-part inventories and faster commissioning in industrial facilities. Flexible control logic: The 2NO-2NC arrangement provides versatile trip/close interlocks and interlock schemes, enabling safer start/stop sequencing and improved fault isolation. Business impact: reduces wiring complexity and lowers maintenance hours by enabling standardized control circuits. Application: centralized power distribution with varied protection logic requirements in manufacturing and process industries. Bottom-feed fusible protection: Bottom feed and fusible design simplify wiring, fuse coordination, and enclosure wiring runs. Business impact: faster installation, easier troubleshooting, and fewer wiring mistakes, translating to lower labor costs. Application: new builds and retrofit projects in panels rated for rugged service. Ground fault protection integration: Ground fault with control power transformer enhances personnel safety and system reliability. Business impact: proactive fault detection reduces arc-flash risk and unplanned shutdowns. Application: electrical rooms and MCCs serving heavy machinery where fault currents must be rapidly interrupted. Rugged enclosure compatibility: UL Listed with broad NEMA ratings (1, 3R, 4, 12) supports installation in varied environments, from clean electrical rooms to harsh industrial spaces. Business impact: expanded application reach, fewer enclosure substitutions, and improved regulatory compliance. Application: harsh manufacturing floors, chemical plants, and outdoor switchgear installations with long service life. Optional features and future-proofing: Catalog notes include Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions. Business impact: scalable protection architecture minimizes future retrofit costs and supports ongoing safety program upgrades. Application: evolving safety standards and plant modernization programs.

FAQs

Ensure mounting fits a three-pole enclosure and accepts bottom-feed wiring. Verify compatibility with 2NO-2NC contact configuration and fusible protection. Confirm system voltage rating of 480V and control voltage of 120V, plus adherence to UL Listed requirements and the applicable NEMA enclosure standards (1, 3R, 4, 12). Use the optional auxiliary provisions if your control logic requires additional contacts.
A 2000A rating supports direct protection for large motors and feeders, reducing the need for multiple devices. Fuse selection should align with the device’s fusible protection configuration and system voltage (480V). This enables coordinated protection within a single assembly, improving reliability while simplifying maintenance and spare-part inventory.
Yes. The switch is designed for 480V system voltage while using a 120V control circuit. This pairing supports common industrial control schemes and enables safe, reliable operation in large switchgear and control panels. Bottom-feed, three-pole protection further enhances compatibility with standard motor and process equipment layouts.
The CB2033B120480GAX7 carries UL Listed certification and is rated for multiple NEMA enclosure environments (1, 3R, 4, 12). Optional features like Ground Fault Relay and auxiliary provisions help meet broader safety and reliability requirements for industrial facilities, contributing to regulatory compliance and safer plant operations.
Expected ROI comes from reduced downtime, fewer protective devices, and streamlined maintenance due to a single robust switch covering high-current protection. With optional ground fault and fuse-detection features, preventive maintenance becomes easier, and spare parts inventories are simplified. The device’s rugged UL Listed construction plus NEMA-rated enclosure supports longer service life in demanding environments.
