Resettable protection for process and industrial controls

With the continuing automation of industrial processes, remote monitoring and control is becoming increasingly important in industrial-control arenas. Modern installations demand the use of control systems that guarantee accurate communications, not only between different decision centers and different machines, but throughout an installation. Many designers are providing the means to monitor the environment in such facilities as factories, schools, and office buildings and to communicate the resulting information back to a central processor. This feedback is then used to control the surrounding environment. However, because these systems can be damaged by faults that result in excessive current, industrial-control and monitor manufacturers are increasingly turning to Polymer Positive Temperature Coefficient (PPTC) resettable fuses to limit fault currents and improve reliability
