Selling Policy 25-000 - Distribution and Control Products and Services
The 2000 A amperage rating enables direct switching of high-current feeders and large motors, reducing the need for extra protective devices upstream. This simplifies coordination within MCCs and distribution panels, lowering install time and potential fault points. The 120 V control voltage and 480 V system voltage support cross‑voltage configurations, streamlining design and stock management while expanding compatibility across facilities. The 2 NO-2 NC contact configuration provides flexible interlocking and signaling paths, enabling safe start/stop sequencing for complex motor control circuits. Bottom feed fuse configuration simplifies wiring harness routing and protective device coordination, reducing panel depth and improving accessibility during maintenance. The ground fault capability with a control power transformer enhances safety and fault isolation, helping meet stricter protection requirements in critical environments. The three-pole, three-wire design delivers robust, reliable switching for large switchgear assemblies, while UL Listed and NEMA-rated construction ensures enclosure compatibility in harsh facilities. Optional features such as ground fault relays and auxiliary contacts support scalable signaling and code compliance, reducing lifecycle costs and easing retrofits in aging plants.

FAQs
Install as a bottom-fed device in a suitable enclosure, mount the switch on standard rails or mounting plates, connect the 3-wire feeds to the 3 poles, and wire the 120 V control circuit from the control power transformer. Use the fusible configuration as specified and verify the 2 NO-2 NC contact connections align with your interlock and signaling scheme. Ensure UL Listed compliance and appropriate NEMA enclosure compatibility for your environment.
Key ratings include 2000 A amperage, 120 V control voltage, 480 V system voltage, three-pole operation, 2 normally open and 2 normally closed contacts (2 NO-2 NC), bottom feed, and fusible protection. It is UL Listed and supports NEMA 1, 3R, 4, and 12 enclosures, with optional ground fault and auxiliary options.
Yes. The device is rated for 480 V system voltage and 2000 A switching, with a three-pole configuration ideal for motor control centers and large feeders. Its fusible protection and optional ground fault features help meet motor protection and safety standards in industrial facilities.
The CB2033B120480G7 is UL Listed and supports multiple NEMA enclosure ratings (1, 3R, 4, 12), which facilitates installation in diverse environments. Optional features such as ground fault relay and auxiliary contacts can help meet specific safety codes and signaling requirements in your facility.
The device combines high-current protection with a control transformer in a compact bottom-fed design, reducing wiring complexity and panel depth. Its robustness and UL/NEMA compliance minimize downtime, improve safety signaling, and simplify future retrofits, delivering lower maintenance costs and faster commissioning over the equipment lifecycle.
