I was taught circuit breaking in secondary class 2, how come there was no circuit breaking mechanism to have stopped the power flow here?

A circuit breaker acts based in the instructions it receives. If it doesn’t receive an instruction to open and cut electricity supply, it will remain closed. Or probably the circuit breaker received an instruction to open but failed to open, then their is another protection function called protection against CB fail
