Thermal cut outs

[Emmo]

I am making up a new power pack for my exhibition layout, featuring three transformers all delivering power to the layout for one item only, i.e.. 1)15v AC to feed the track controller, 2) 15v AC to feed the point motors and c) 12v DC to operate layout lights (station, buildings etc).

I would like to incorporate thermal cut outs in each of the low voltage circuits. I have used 1amp in my old power pack which tended to cut out after a few hours and required a rest before it would power up again. Has anyone else used these things and if so, what rating and what sort did you use? Gaugemaster do them but at about £6 each they are pretty steep as I want three and possibly a spare or two.

...also, any danger by not using any at all?

Thanks
