Simple Mcb Simple Circuit Breaker Diagram. Loaded on the left side of a miniature circuit breaker to indicate the fault trip state of the circuit breaker. This was a simple explanation of a miniature circuit breaker working principle.
As i shown in the above diagram. Main circuit breaker type is 25a mcb at the incoming line 5x10mm from esmdb 3 the mcb rate is 40a mcb at the dimmer group. Same we use single pole mcb in our distribution boards.
An mcb is very simple easy to use and is not generally repaired.
Mcb miniature circuit breaker is a re settable device designed to protect a circuit from short circuits and overcurrents. Same we use single pole mcb in our distribution boards. The trip curve of an mcb s b c d k and z curves tell us about the trip current rating of miniature circuit breakers trip current rating is the minimum current at which the mcb will trip instantaneously. As i shown in the above diagram.
