    A 1 pole miniature circuit breaker (MCB) is an electrical switching device designed to protect electrical circuits from overload and short circuits. It consists of a single pole, which means it can interrupt the flow of current in one conductor. The MCB is typically installed in residential, commercial, and industrial electrical distribution panels.

    The MCB operates on the principle of thermal and magnetic tripping mechanisms. It has a bimetallic strip that heats up due to the flow of current, and when the current exceeds the rated value, the strip bends and trips the circuit breaker, interrupting the current flow. Additionally, the MCB has a magnetic coil that responds to high-current surges, such as those caused by short circuits, and quickly trips the breaker to protect the circuit.

    ATO provides 1 amp, 2 amp, 3 amp, 4 amp, 6 amp, 10 amp, 16 amp, 25 amp, 32 amp, 40 amp, 50 amp, 63 amp 1 pole miniature circuit breaker with DIN rail mounting. The 1 pole MCB is compact in size and easy to install. It has a rated current and breaking capacity specified by the manufacturer. It is equipped with a toggle switch for manual control, allowing users to turn the circuit on or off. The 1 pole MCB is an essential component in electrical systems, ensuring the safety and protection of circuits from overloads and faults.
