Can anyone advise me what this is?

It's 3 x 2 x 1 cm, plus the base, marked Otter, Buxton England and has the numbers 541560 on the white part in the photo. It is installed in-line in the wiring to a small windlass on my little motor-sailer.

Although this component appears to be many years old, Otter are still around, making temperature control equipment.

Has anyone any experience of using one of these? I have e-mailed Otter for advice but would appreciate any other assistance from the forum.

Thanks.

Some sort of self-resetting, probably thermal, breaker?

A big capacitor to smooth out jaggies that a hefty motor might send back down the line?

Just guessing really

EDIT: Scratch the capacitor, that would be between supply and return, not inline.

Possibly a diode ??? Cant see what else would be in-line. Stick a meter on it & see.

As PRV says, it looks like a self resetting cutout device, possibly thermal or current sensing, not too sure which, but below is the link to the what i think is the modern version of it

Otter thermal cutout for a Jaguar perhaps.

Thermal cut-out looks to be favourite.
Have you put a multi-meter across it?

Looks a useful bit of kit

No continuity in either direction. But the windlass doesn't operate with it in line, not yet tried it without.

If its not working, then you should pull the rivets out with pliers or mole grips and take a picture of the insides for us to have a look, would get a better idea of what makes it tick and exactly what it is

It's a Otter circuit breaker, they are still around at Buxton, and may be able to to supply you a spare.

The little printed strip of paper has the part number on.
