The TRM1 is a Tri-Onic® time-delay midget fuse designed to provide supplemental protection for small motors, small transformers, and other high inrush load circuits. It is rated at 250 volts AC with a 1 ampere rating and features a 12-second time-delay at 200% rating, allowing it to tolerate temporary inrush currents while protecting against sustained overcurrent conditions. The fuse has compact dimensions of 1 1/2" × 13/32" (10mm × 38mm) and is compatible with UltraSafe™ fuse holders. This time-delay characteristic makes it ideal for applications requiring supplemental circuit protection where conventional fast-acting fuses would nuisance-trip, such as motor startup circuits and transformer energization.
