TRS1R - 1 Amp Fuse

TRS1R - 1 Amp Fuse

The TRS1R Class R fuse is a straightforward option for dependable protection on low-amp circuits. It’s rated at 1 amp and built to handle up to 200 kA at 600 VAC, so it’s more than capable when a serious fault occurs. One practical feature is the time-delay option. It won’t trip the second a motor starts, or a transformer energizes, helping avoid those annoying, unnecessary shutdowns. At the same time, it still reacts fast enough during a real fault to limit damage. That balance is what you’re after in most systems. It’s also a current-limiting fuse, so it helps cut down the amount of energy that passes through during a short circuit. That can help protect downstream components. The cartridge-style design keeps things simple, and since it’s made for Class R rejection holders, you get an extra layer of protection against installing the wrong fuse. Nothing fancy here—just a fuse that does its job reliably.
