An Indo Asian C Curve Single Pole MCB (Miniature Circuit Breaker) is a type of electrical protection device that safeguards a single electrical circuit from overloads and short circuits. The "C Curve" indicates the MCB's tripping characteristics, meaning it will trip (interrupt the circuit) when the current flowing through it reaches 5 to 10 times its rated current. "Single Pole" refers to the fact that it protects a single live wire, commonly used in residential settings.
