Is this a Circuit Breaker?

[mfschu]

I'm looking over my electrical wiring in order to replace my lead acid battery with four LifePO batteries. I ran across this wiring device and I'm not sure what it is. From my Google searches it looks like it might be a circuit breaker? I don't recall seeing any discussions of this item on the Forum and wondering what's it is there for and how it effects the electrical system if it ever trips. Thank You

Yes, it is an automatic reset circuit breaker, designed to break the circuit temporarily in case of an overload and then automatically reset.
