What Is Instantaneous Trip Circuit Breaker?
An Instantaneous Trip Circuit Breaker is a type of electrical circuit breaker designed to detect and interrupt short-circuit conditions almost immediately. It provides rapid protection by tripping and disconnecting the circuit when a high-level current surge occurs, preventing potential damage to electrical equipment and reducing the risk of fire.
