<h3>Circuit Breakers</h3>
Circuit breakers are automatic electrical switches designed to protect electrical circuits from damage caused by overcurrent, short circuit, or ground fault conditions. They function by automatically interrupting the flow of current when abnormal conditions are detected, thereby preventing damage to equipment and minimizing the risk of fire or electric shock.
&nbsp;
Key Features and Functions
* Overcurrent Protection: Circuit breakers are equipped with trip mechanisms that detect abnormal levels of current flowing through the circuit. When an overcurrent condition is detected, the circuit breaker trips and interrupts the flow of current to prevent damage to the circuit and connected devices.
&nbsp;
* Short Circuit Protection: Circuit breakers can quickly respond to short circuit faults by opening the circuit and isolating the faulted section from the rest of the system. This helps prevent extensive damage and minimizes downtime.
&nbsp;
* Thermal and Magnetic Tripping Mechanisms: Circuit breakers utilize both thermal and magnetic trip mechanisms to provide comprehensive protection against overloads and short circuits. The thermal element responds to prolonged overcurrent conditions, while the magnetic element responds to sudden, high-current surges.
&nbsp;
* Resettable: Unlike fuses, circuit breakers are resettable after tripping, eliminating the need for replacement components and reducing maintenance costs.
