Special features
With control power transformer
Feature: The CB1233T120480G5 delivers a 1200A amperage rating, enabling direct switching of heavy loads without oversized contactors. Business impact: This reduces panel complexity, minimizes wiring and bus bar requirements, and boosts overall system efficiency by cutting switchgear footprint and thermal losses. Application: Ideal for distribution panels, motor control centers, and high‑current feeders in manufacturing plants where reliability and downtime are costly. Feature: It uses a 1 NO-1 NC contact configuration, giving flexible control logic for interlocks and fault sensing. Business impact: Users gain safer, more predictable protection schemes and fewer miswired circuits during commissioning. Application: Suitable for three‑pole control circuits with both normally open and normally closed signaling in power distribution panels. Feature: Top feed design with fusible protection and an integrated control power transformer simplifies wiring and fault protection. Business impact: Installation time is reduced and protection coordination is improved, lowering commissioning cost. Application: Great for top‑fed switchgear and installations requiring coordinated fusible protection and control power within a single enclosure. Feature: NEMA ratings compatibility and UL Listed certification support deployment in diverse environments. Business impact: Compliance reduces regulatory risk and extends service life in challenging environments. Application: Indoor and outdoor installations, dusty or damp locations, and industrial settings demanding robust protection. Feature: Optional Ground Fault Relay, Auxiliary Contact Provisions, and Kirk Provisions are available to tailor protection and monitoring. Business impact: Customers can customize sensing and signaling without additional field wiring, cutting downtime during upgrades. Application: Useful in circuits requiring ground fault detection, extended signaling, or retrofits within existing protection schemes.

FAQs

Yes, CB1233T120480G5 supports top feed and three‑pole configuration with standard mounting interfaces for common enclosures. Verify wiring per the Eaton data sheet and ensure the control power transformer is wired per the control diagram. The 180 lb unit should be handled with appropriate lifting and secured within a compatible switchgear panel to meet UL safety requirements.
The switch is rated for 1200A with a 120 V control voltage and a 480 V system voltage, featuring a 1NO-1NC contact configuration and fusible protection. It is designed for three‑pole, three‑wire operation and supports NEMA 1, 3R, 4, and 12 enclosures with UL Listed safety. Optional ground fault relay and auxiliary contacts extend protection and signaling options.
This device excels in heavy electrical distribution, motor control centers, and industrial processes requiring high‑current switching with reliable fault protection. It suits manufacturing lines, packaging and material handling systems, and power distribution panels where uptime and robust protection are critical and where a control transformer can simplify control wiring.
CB1233T120480G5 is UL Listed and supports multiple NEMA enclosure ratings (NEMA 1, 3R, 4, 12) for diverse environments. This combination helps ensure electrical safety, enclosure suitability, and regulatory alignment for industrial deployments, with optional provisions for advanced protection schemes as described in the catalog notes.
The integrated control power transformer and fusible protection simplify installation and reduce field wiring, which lowers commissioning and maintenance time. High current capability and UL/NEMA compatibility translate to longer service life and fewer trip events, improving overall equipment effectiveness and return on investment for critical power distribution applications.
