TRS25R - 25 Amp Fuse

TRS25R - 25 Amp Fuse

The TRS25R is a 25 amp Class R fuse made for circuits where a quick surge at startup is just part of the job. Instead of blowing right away, it gives equipment a moment to get going—then steps in if there’s an actual problem. It’s a time-delay, current-limiting fuse, so you get that balance between not tripping too early and still protecting your system when it counts. That’s especially useful on motors, transformers, and similar loads. With a 200 kA rating at 600VAC, it’s built for higher fault conditions. When something goes wrong, it helps contain the damage instead of letting it spread through the system. The design itself is simple—a cartridge-style Class R fuse that fits easily into standard setups. No indicator, no extra parts. Just install it and move on.
