An Indo Asian B Curve Double Pole (2P) MCB (Miniature Circuit Breaker) is a safety device designed to protect electrical circuits from overloads and short circuits in single-phase systems. The "B Curve" indicates its tripping characteristics, meaning it will trip relatively quickly for short circuits and slightly slower for overloads. The "Double Pole" (2P) designation means it will disconnect both the live (phase) and neutral wires simultaneously when a fault occurs, enhancing safety.
