The Eaton Industries MCCB power switch has a rated continuous current Iu of 225A and rated voltage of 440V. It features a rated cut-off capability Icu at 400 of 25kA, and an overload protection setting range of 225A. It also includes a short-delayed setting range of 1500 – 2500A, and an instantaneous short circuit setting range of 6 – 10A. Complemented by the NZM..-AF..NA circuit-breakers, it can be applied universally with just four compact sizes. It provides flexibility due to its modular function groups and offers thermomagnetic releases for systems and cable protection, as well as fixed overload releases. This switch is in compliance with UL/CSA and IEC regulations, as indicated on the rating plate, which also bears the IEC switching performance values.
