Littelfuse Polyswitch Resettable Fuses

Raychem Brand: Raychem

The Littelfuse Polyswitch is a resettable device that performs like a fuse under overcurrent conditions, but is unique in that it will reset. As soon as an overcurrent condition is reached the Polyswitch heats up to its trip temperature.

  • UL and TUV approved
