MCBs, also known as miniature circuit breakers, are crucial components in electrical systems that provide protection against electrical faults. They serve as automatic switches that interrupt the flow of electricity when abnormalities such as short circuits or overloads occur. This section delves into the definition of MCBs, their significance in ensuring home electrical safety, and the evolution from traditional fuses to modern circuit breakers.
MCBs are automatic switches that interrupt current flow during faults or overloads, crucial for home safety by preventing electrical hazards, protecting appliances, and replacing traditional fuses with their faster, resettable design.
This section explores the key elements of MCBs, including sensing elements, triggering mechanisms, electromagnets, and the function of arc runners or arc chutes in extinguishing arcs.
