A trend to design new motors closer to their design limits and the high cost of plant shutdown has increased the need for better protection of smaller three phase motors. A single chip microcomputer relay can be applied to replace thermal overloads which are of limited effectiveness on low and medium voltage machines with comprehensive, economical motor protection. The requirement for different protection features and how they are achieved is presented. All the protection features discussed are commercially available in a compact unit that uses a single chip microcomputer.
