Miniature Circuit Board. Electrocookie mini pcb prototype board solderable breadboard for diy electronics compatible for mini arduino soldering projects gold plated 6 pack multicolor. The main function of an mcb is to switch the circuit i e to open the circuit which has been connected to it automatically when the current passing through it mcb exceeds the value for which it is set.
A miniature circuit breaker mcb is an automatically operated electrical switch used to protect low voltage electrical circuits from damage caused by excess current from an overload or short circuit. The main function of an mcb is to switch the circuit i e to open the circuit which has been connected to it automatically when the current passing through it mcb exceeds the value for which it is set. They are available in the following ratings.
For domestic applications miniature circuit breakers mcb are widely used as an alternative to fuses.
Their rated current depend on the load current of the equipment to be protected and the ambient operational temperature. Small circuit boards have become the norm as more manufacturers use integrated circuit chips. Nowadays we use an mcb in a low voltage electrical network instead of a fuse. For domestic applications miniature circuit breakers mcb are widely used as an alternative to fuses.
