TRF250-400 Tyco Raychem PPTC Resettable Fuse (250V, 400mA, 1 Piece)

TRF250-400 Tyco Raychem PPTC Resettable Fuse (250V, 400mA, 1 Piece)

The TRF250-400 Tyco Raychem PPTC Resettable Fuse is a polymeric positive temperature coefficient circuit protection device designed to protect electronic and electrical equipment against overcurrent conditions. Featuring a maximum operating voltage of 250V and a hold current of 400mA, this radial leaded component increases its resistance during an overcurrent fault to limit current flow. Unlike conventional one time fuses, the TRF250-400 can return to its low resistance state after the fault is removed and the device cools, reducing maintenance requirements.
