Cautions for Design of Intelligent Controller Used for Moulded Case Circuit-Breakers

Introduction was made to application,applicable scope,classification,protection parameters setting and functions of an intelligent controller. The principle and design cautions for the intelligent controller were described. The intelligent controller not only increases the selection range of setting current,but also has three-section protection function and can set long-time delay and short-time delay action time,which makes the product more reliable,thus the product is sure to be applied in moulded case ci...
