Abstract

This paper explains the criteria of selection and coordination between the motor control centers (MCCs) components to meet the need of motor service continuity in the most of industrial processes. The aim behind this study is to obtain high level of coordination between the MCC components which is denoted by Type 2 coordination. The requirements of Type 2 coordination are illustrated in this research; this is according to IEC 947-4-1, where illustrates different methods of meeting these requirements. Also, this research proposed an algorithm to compare between implementing either fuses or circuit breakers (CBs) as short circuit protection device (SCPDs) in the MCC.
