The Littelfuse JTD125ID is a 125 Amp Class J time-delay fuse designed for superior overcurrent and short-circuit protection in industrial and commercial electrical systems. Part of the JTD_ID series, this POWR-PRO® fuse incorporates a time-delay characteristic that allows temporary motor-starting and transformer inrush currents to pass without nuisance opening. The built-in blown-fuse indicator provides quick visual identification of an open fuse, reducing troubleshooting time and simplifying maintenance.
