Eaton Specification Sheet - CB1633T120480AX5
1600 A amperage rating enables a single switch to carry high fault currents, reducing the bulk of parallel devices and simplifying wiring, which translates to lower upfront costs and fewer potential failure points in large switchgear. This high-capacity performance directly supports efficiency gains in heavy industrial panels where downtime is costly and safety must be maintained. 120 V control voltage ensures compatibility with standard plant control circuits, enabling straightforward integration with existing relays and PLC interfaces while reducing auxiliary power needs. 480 V system voltage and 480 V voltage rating allow direct switching of high-power loads without compromising protection integrity, improving reliability during motor starts and heavy load changes. The 1 NO-1 NC contact configuration provides versatile control logic for break-before-make or fail-safe interlocks in protection schemes, enhancing fault isolation strategies across critical equipment. Top feed and fusible protection simplify wiring topology and fuse coordination, enabling cleaner panel layouts and quicker serviceability for maintenance teams. Optional Ground Fault Relay, Blown Fuse Detection, and auxiliary provisions give you scalable protection—without installing additional enclosures—leading to lower lifecycle costs and easier compliance with evolving standards. NEMA 1, 3R, 4, and 12 compatibility ensures robust performance indoors and in moderate-to-severe environments, extending service life in manufacturing floors and outdoor enclosures. The Eaton specification framework and available Kirk provisions support seamless installation, tested compatibility, and faster commissioning in modern control rooms and substations.
