Big savings with 'Micro' motor control centres

Motor control centres have for many years been built using hard wired relays, timers and contactors but the drive to reduce cost has led to the development of the `intelligent' MCC based on programmable digital electronics and fieldbus communications. We use the abbreviation `μMCC' to indicate the underlying technology and reduced size. Wessex water is currently implementing its second generation of these panels. All routine operator interaction with the MCC is via a human machine interface (HMI) mounted on the common control section of the panel.
