Circuit breaker

A **circuit breaker** is an electrical device designed to protect an electrical circuit from damage caused by overloads or short circuits. It automatically interrupts the flow of electricity when a fault is detected, preventing potential hazards like electrical fires or equipment damage. Key functions and characteristics of circuit breakers include: 1. **Overload Protection**: Circuit breakers monitor the current flowing through the circuit. If the current exceeds a predetermined level, indicating an overload, the breaker will trip to cut off the power.
