Black Circuit Breaker's function

A black circuit breaker's primary function is to act as a safety device that protects an electrical circuit from overcurrents caused by overloads or short circuits. It automatically interrupts the flow of electricity when it detects an unsafe condition, preventing potential hazards like electrical fires and damage to appliances. While the color "black" usually distinguishes it as a standard single-pole breaker for general use, its fundamental protective role remains the same across all circuit breakers.
