An MCCB is short for Molded Case Circuit Breaker. It’s an electrical protection device that helps keep wiring and equipment safe. When a circuit draws too much current for too long, that’s an overload, and the MCCB trips to stop the flow. If there’s a sudden fault, called a short circuit, it can cut power even faster. In simple terms: an MCCB is a sturdy on‑off safety switch that automatically shuts a circuit down when something goes wrong.
