Eaton fuse disconnect models provide up to 100 Kilo Ampere Interrupting Capacity (KAIC) fault current protection and a current limiting capability, which offers an advantage over circuit breakers by protecting equipment downstream.
The interrupting capacity from 25 to 150 kA allows a single unit to address multiple applications, which helps reduce product stocking.
Improvements in the arc-interruption system, for example, increase interrupting capacity and minimize space requirements.
