Eaton CB1633T120480C Bolted Pressure Contact Switch - UL

With a 1600A amperage rating, this switch supports true high-current switching in large equipment and main feeder panels. The result is fewer devices in parallel, lower voltage drop, and improved efficiency during peak load, translating to lower lifecycle costs. It’s well suited for rugged plant power distributions and heavy machinery where reliable isolation and fast fault clearance are critical. Having a 120V control voltage simplifies integration with existing control circuits and reduces the need for additional interposing devices. The built-in control transformer enables safe, coordinated operation with low-voltage relays and CTs—streamlining wiring and enabling precise protection coordination. Rated for 480V main voltage, the device accommodates standard industrial machinery and distribution equipment without custom interfaces. Coupled with a top-feed design and three-pole, three-wire configuration, it delivers clean wiring routes and straightforward installation in panel interiors and switchboards. Fusible protection helps isolate faults and limit fault energy, reducing damage to downstream equipment and simplifying maintenance after events. The bolted pressure contact design provides robust mechanical contact at high currents, helping maintain delivery integrity even under demanding conditions. Including an AFGF relay and matched CTs streamlines sensing and protective coordination, minimizing field wiring and calibration time. This kit-ready approach accelerates commissioning and supports consistent performance across Eaton switching devices in the same family. UL Listed certification adds confidence for safety compliance and audit readiness, while Eaton’s specification sheets and catalogs provide clear installation guidelines and compatibility notes.
