What is AC MCB?
Miniature circuit breaker (MCB), also known as air switches, provide basic short circuit and overload protection. A device used to protect a circuit in case of excessive current. Excessive current can be caused by overload, short circuit, or unreasonable circuit design. Equivalent to the advanced version of the fuse can be reset without replacement.
AC MCB is the MCB used for the circuit system of alternating current，It is generally used for circuit protection under the AC sinusoidal waveform.
Usually it is suitable for household, industrial or commercial power, such as AC voltage 110V/230V/380V/415V. In addition we provide the DC MCB of the direct current is for circuit protection under the direct current circuit.
