FAQs
Key installation factors include the three-pole, bottom-feed configuration with fusible protection, and the 16 in depth, 32 in height, and 24 in width footprint. Plan for a suitable enclosure (NEMA-rated) and ensure wiring aligns with the 1NO-1NC contact arrangement. The unit weighs 190 lb, so provide adequate mounting support and clearance for maintenance and cooling. Optional features such as grounding provisions and auxiliary contacts should be integrated per system requirements.
This switch is rated for 2000A at a system voltage of 480V with a 120V control circuit and a 1NO-1NC contact configuration. It uses fusible protection and is designed for 3-pole operation with ground fault capability through a transformer. The device is UL Listed and compatible with NEMA 1, 3R, 4, and 12 enclosures, making it suitable for a wide range of industrial protection schemes.
Yes. The three-pole, bottom-feed design with 2000A rating and 480V system compatibility makes it well-suited for motor control centers and heavy switchgear. Its charge-before-close mechanism and fusible protection help coordinate with MCC protections, while optional features like single-phase protection and auxiliary contacts support complex MCC protection schemes.
The CB2033B120480GAX5 carries UL Listed certification, ensuring safety compliance for industrial installations. Its NEMA compatibility (1, 3R, 4, 12) further supports utilization in varied enclosure environments and aligns with common industry practice for rugged electrical distribution equipment.
The unit is covered by Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. Optional protection provisions—Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk and Auxiliary Provisions—can be specified at purchase to extend protection, simplify maintenance, and maximize return on investment in retrofit or new-build projects.
