A Miniature Circuit Breaker (MCB) is a type of circuit protection device designed to automatically switch off electrical circuits in the event of overloads or short circuits. These compact and efficient breakers are commonly used in residential, commercial, and industrial applications to safeguard electrical systems and equipment from damage. MCBs offer quick response times, adjustable trip settings, and high breaking capacities to ensure reliable protection. With their small size and versatile features, Miniature Circuit Breakers are essential components for ensuring electrical safety and preventing hazards in various environments.
