FAQs
CB3033T120208RAX uses a top feed fuse configuration and a three-pole, three-wire arrangement suitable for bolted pressure switch assemblies in Eaton panels and compatible enclosures. It supports SPVR with capacitor trip and optional Kirk provisions, auxiliary contacts. When installing, ensure the enclosure is rated to NEMA 1, 3R, 4 or 12 and provides enough space for the 22.5 in depth, 28 in height, and 40 in width of the unit.
Key specs include a 3000A amperage rating, 120 V control voltage, 208 V system voltage, top-feed fuse configuration, three-pole, three-wire construction, and fusible protection. The device uses a single-phase capacitor trip relay (SPVR) for improved fault clearance and is UL Listed. It is designed for protective switching in industrial power distribution and motor circuits.
Yes. The CB3033T120208RAX is rated for 3000A with a 208 V system voltage, three-pole operation, and fusible protection, making it well-suited for high-current motor feeders and heavy-duty control panels. Its SPVR provides coordinated tripping, reducing inrush-related disturbances and protecting downstream equipment in 208 V configurations.
The CB3033T120208RAX carries UL Listed certification, which supports safety compliance and regulatory acceptance in many markets. Its NEMA-rated enclosure compatibility (1, 3R, 4, 12) further informs installation options in diverse environments. While other certifications aren’t listed in the data, the UL listing combined with NEMA compatibility typically aids warranty and service considerations for OEMs.
Maintenance considerations include monitoring fuse indicators and trip function performance, given its fusible protection and SPVR. The unit carries Eaton’s warranty (one year from installation or eighteen months from shipment) and UL safety certification, contributing to reduced downtime and predictable service costs. ROI comes from improved protection, fewer unexpected trips, and longer asset life in demanding environments.
