I use 1.1A hold PTC's in series with motors using the ERR Cruise Commander Lite to prevent damage due to a motor stall.  I cooked one of my beta test units when the K-Line Interurban snagged a switch and stalled the motor, that was my solution.  So far, no more cooked boards in the half dozen I've installed in my stuff and the others that have gone out the door.  Of course, any protection is better than none, and I like the PTC for inside units as you don't have to open them up to fix anything if the trip.
