Reliable protection of low voltage distribution systems with precision breakers

We live in a world that is becoming more and more acquainted with electronic or electronically controlled devices and systems. It may be prudent however, to acknowledge that, depending upon the application and the environment, certain advantages and benefits that are normally associated only with the more costly electronic solutions, can be achieved by using less sophisticated technologies. Furthermore, the importance of good economic engineering design, whilst being a given, is regrettably not always fully appreciated or implemented. As a general rule, simple solutions usually result in the best and most economic solution. Such solutions are often found in some unexpected parts of the world. This paper describes a method of achieving significant cost savings in low voltage electrical reticulation and distribution networks, through the judicious application of appropriate overcurrent protection components in these systems. These overcurrent protection components have become known as precision breakers
