Molded Case Circuit Breakers (MCCBs) are protective devices designed to automatically disconnect electrical circuits in the event of overcurrent, short circuits, or ground faults. Encased in a molded insulating material, MCCBs are capable of handling higher current ratings, typically up to 2500A, making them suitable for industrial and commercial applications. They provide adjustable trip settings, allowing precise protection tailored to specific circuit requirements, and are crucial in preventing damage to electrical equipment, ensuring safety and reliability in power distribution systems.
