FAQs
Installers should plan for top-feed configuration and fusible protection, connect the 120 V control voltage to the control power transformer, and ensure a three-pole, three-wire setup with 2 NO-2 NC contacts. Verify enclosure compatibility with the site environment (NEMA 1/3R/4/12) and observe ground fault options if required by safety standards.
This switch is rated for 2000A amperage, with a system voltage of 480 V and a control voltage of 120 V. It features three poles, a 2 NO-2 NC contact configuration, and fusible protection for reliable, field-proven performance in industrial power distribution.
Yes, the CB2033T120480G7 is UL Listed. It is compatible with NEMA 1, NEMA 3R, NEMA 4, and NEMA 12 enclosures, supporting diverse environments from indoor panels to harsher outdoor or washdown settings.
Its three-pole, fusible design with top feed and control power transformer makes it ideal for large motor feeders, switchgear assemblies, and control panels in manufacturing, processing plants, and heavy industry where reliable protection and quick fault isolation are critical.
Regular inspection of control wiring, fuse status, and ground fault relay options is recommended. The device’s rugged construction and UL/NEMA compliance support longer service life and reduced downtime, delivering a favorable total cost of ownership in facilities with demanding continuous-operation requirements.
