Lofrans v Generic Circuit Breaker

I'm installing a new Lofrans Cayman Windlass.
I have a choice of a Lofrans 100A thermal circuit breaker or say a Blue Sea 187 100A thermal CB at half the price.
I haven't been able to find any technical data for the Lofrans CB except a statement ' it works following a specific time / current characteristic curve in order the windlass may supply the best performance'. Is this worth paying extra for or is this just a b/s sales pitch?
I suppose basically my question is will the Blue Sea CB do the same job?

When I bought and installed a Lofrans Tigres about a decade ago, the tech guy at the then UK importer told me that the price of the Lofrans breaker was silly and a generic one woud do just as well. There is a significant difference in the way breakers operate, much of it beyond me, but someone's bound to be along with technical info on that.
 
For your windlass a suitably rated BlueSea one will be perfectly OK. My Lofrans works fine with a generic breaker, as do millions of others i would guess.

The operative word in both those is thermal which they both are.

The other type is magnetic

The very simple description is
In thermal the current heats up a bimetal strip that causes the CB to trip.
In magnetic the current causes a magnetic field to flow thus tripping the CB to trip.
 
EC Smith used to be Lofrans UK distributors and supplied generic breakers, which they still sell.

Thanks for reminding me. That's who I was referring to in post #2.

Incidentally, since I was fitting a 1kW windlass, somewhat over-rated for my 8mm chain on a 32-footer, their tech chap suggested I might fit an 80A breaker rather than the normal 100W, which I did. It tripped just once in six years, lifting a chain with links as big as your head from a Portuguese harbour bottom. Still got it to the surface, though, where it could be tied off and released. I liked the idea of being unable to over-stress the motor.
