Eaton CB1633B120208RAXCT Pringle bolted switch - UL Listed
Part Number: CB1633B120208RAXCT
Quick Summary
The Eaton CB1633B120208RAXCT is a bolted pressure contact switch for high-capacity, three-pole protection in industrial power systems. Engineers often struggle with reliable fault sensing and fast-tripping in demanding switchgear environments. UL Listed certification and broad NEMA ratings (1, 3R, 4, 12) help ensure code compliance across indoor and outdoor installations. Its 1600A amperage, 208V system voltage, and 120V control voltage support heavy-load automation while enabling a compact bottom-feed footprint. With SPVR capacitor-trip and optional ground-fault or blown-fuse features, this unit supports scalable protection for switchgear, motor control centers, and critical panels. This combination translates to reduced downtime, easier procurement, and faster start-up for legacy or greenfield projects.

FAQs
Plan for a bottom-feed, three-wire configuration with fusible protection and a compact footprint. Allocate space for 200 lb hardware, consider access to SPVR components, and ensure alignment with control transformers if the optional transformer is used. Secure mounting and proper clearance support safe maintenance and reliable operation over the life of the panel.
The unit supports up to 1600A with a 208V system voltage and 120V control voltage, with voltage ratings up to 208V and corresponding max voltage. NEMA 1/3R/4/12 compatibility enables use in a wide range of environments. These specs guide fuse coordination, trip timing, and interface with protective relays in motor feeders and switchgear.
Yes. UL Listed certification and NEMA ratings 1, 3R, 4, and 12 provide proven protection across indoor and outdoor installations. Its fusible design and SPVR trip device enhance reliability in motor control centers and switchgear, while Optional ground fault/redundant protection supports stringent environment controls and compliance requirements.
The CB1633B120208RAXCT carries UL Listed certification and is rated for multiple NEMA enclosures (1, 3R, 4, 12), supporting compliance with common industrial electrical codes. While CE or IP ratings are not listed here, UL and NEMA conformance are widely recognized for project approvals, maintenance planning, and contractor acceptance.
The high-capacity protection reduces the need for multiple devices, potentially lowering initial hardware costs and installation time. Optional features like Ground Fault Relay and Blown Fuse Detection support proactive maintenance and downtime reduction. The one-year warranty (or 18 months from shipment) provides a predictable risk buffer for project budgets.
