Mcb Circuit Breaker Diagram. Miniature circuit breaker mcb a miniature circuit breaker basically is an electromagnetic device that automatically operates or breaks the circuit if the current in the circuit reaches to a predetermined value. An mcb or miniature circuit breaker is an electromagnetic device that embodies complete enclosure in a molded insulating material.
This deflection of bi metallic strip releases a mechanical latch. Mcb miniature circuit breaker is a re settable device designed to protect a circuit from short circuits and overcurrents. Miniature circuit breaker mcb a miniature circuit breaker basically is an electromagnetic device that automatically operates or breaks the circuit if the current in the circuit reaches to a predetermined value.
Miniature circuit breaker mcb a miniature circuit breaker basically is an electromagnetic device that automatically operates or breaks the circuit if the current in the circuit reaches to a predetermined value.
In distribution board we get phase wire supply from the main circuit breaker and connect to all single pole mcb 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. As this mechanical latch is attached with the operating mechanism it causes to open the miniature circuit breaker contacts and the mcb turns. Figure 3 below is a look at the inside of a miniature circuit breaker mcb.
