Low-voltage Fuses and Circuit Breakers
The paper is attempting to describe in a simple way the physical background of low-voltage fuses and circuit breakers operation in conditions of high short-circuit currents. Further, it attempts to draw some conclusions from their operational peculiarities, that substantially influence the practical application of fuses and circuit breakers.
Introduction
Under the slogan “Safety First” are pr
