Intelligent circuit breaker. Engineers have long considered circuit protection a stable if somewhat unglamorous area. However, that stability is diminishing rapidly.New sophisticated devices reshape the way engineers apply circuit protection and open new possibilities for the savvy designer.Electronic systems are shrinking and circuit-protection devices are no exception. To take up less space, circuit breakers may double as power-control relays. Programmability has also come to circuit breakers. Smartprotectors sport programmable trip values and overload time delays.More-sophisticated protectors measure and report voltage and current values, alert control systems about tripped conditions, and can be reset remotely.As global markets become more important, designers must consider how circuit-protection dMany smart breakers include sensing circuits. These sensors feedback information to PLCs or other control units on such factors as circuit status, current flows, and other relevant data. Some solid-state circuit breakers provide an analog output signal proportional to current. evices can meet both domestic and international standards.Programmable technology using solid-state power control makes it possible to monitor and limit maximum current flow during short circuits. Embedded microcontrollers let engineers program both breaker trip points and speed profiles on the fly.
