How to acquire CIRCUIT BREAKER data from simulink ???

my main objective is to design a simple 2bus power system with fault occuring at the middle of the bus. let it be LLLG fault. Post fault samples of three phase current, and voltages needs to be collected from the circuit breaker of the bus bar 1 and 2 at source 1&2. By using the fault signal data wavelet decomposition needs been performed. how to do it?
