How can i create a circuit breaker or controllable switch in simulink

I am trying to create a circuit to model power usage within a distribution system, within this are circuit breakers but there isnt a circuit breaker within the simulink database without moving to simscape. A simple cuttoff switch would work but i cant seem to find one, is there way of creating one?

I have seen these already but i am unsure if they fit into a purely simulink based circuit as they are simscape parts. if they do fit i am unsure of how to do this.
