MCBs versus Fuses in Low-Voltage Applications: Critical Analysis Using the 3-AND Convergence Classifier

Abstract

The protection of any electrical installation is one of the most important considerations in the field of electrical engineering. The electrical installation should be protected against hazards such as overload current and short circuit current conditions. The protection devices studied in this paper are the Miniature Circuit Breaker (MCB) and the High Rupturing Capacity (HRC) Fuse. Using a new tool known as the 3-AND Convergence Classifier, it was observed that the MCB is the most reliable in terms of offering protection against the damage caused by overload currents and the destruction caused by short circuit currents.
