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

TL;DR

This paper compares MCBs and fuses in low-voltage electrical protection, using the 3-AND Convergence Classifier, and finds MCBs to be more reliable for overload and short circuit protection.

Contribution

It introduces the 3-AND Convergence Classifier as a new analytical tool for evaluating protection devices, demonstrating its effectiveness in comparing MCBs and fuses.

Findings

MCBs are more reliable than fuses for overload protection

MCBs better prevent damage from short circuits

The 3-AND Convergence Classifier effectively evaluates protection device reliability

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.
