Protect critical low-voltage circuits and keep security systems online with the Mersen TRM1 Tri-Onic time-delay midget fuse. Designed for supplemental protection, this 1A, 250V AC Tri-Onic fuse delivers dependable inrush tolerance—providing 12 seconds of time-delay at 200%—so motors, small transformers and other high-startup-load devices operate without nuisance interruptions.
