Help identify a part

[skillz]

I found this part tearing down a 3-way speaker with a horn tweeter,mid,sub .
i am not sure what it is or used for as the wires weren't connected in any order and their was no crossover present, the only other stuff in the box was 3 different caps.
I was wondering what they are and what they are used for.

It's a 1.5amp, 50volt thermal overload, probably self resetting.

That is exactly what it is. Crude way of protecting elements but effective.

would it be useful in a crossover for a 2 way or is it for a peizo horn tweeter.
just trying to figure out if i should just toss it or keep it, trying to set up 2 way but only have caps at the moment canada sucks for getting crossover parts without paying a but load for shipping
