What Does PCB Stand For?
PCB stands for Power Circuit Breaker
A Power Circuit Breaker (PCB) is a protective device designed to automatically interrupt electrical circuits to prevent damage from overcurrent conditions, short circuits, or electrical overloads. PCBs ensure the safe operation of electrical systems by quickly disrupting the flow of electricity, thereby minimizing the risk of fire, equipment failure, and potential hazards. These devices are essential in maintaining system reliability and safety in various applications, including industrial, commercial, and residential settings.
