TRS350R - 350 Amp Fuse

TRS350R - 350 Amp Fuse

If you're protecting high-value equipment, this isn’t the place to cut corners. The TRS350R 350 amp Class R fuse is built for real-world electrical systems where overloads and short circuits aren’t “if”—they’re “when.” This is a time-delay, current-limiting fuse, which means it gives your equipment room to start up without tripping unnecessarily, while still reacting fast when there’s a serious fault. The knife-blade design makes installation solid and secure, especially in heavy-duty fuse holders. And with a 200 kA interrupting rating at 600VAC, it’s more than capable of handling high fault conditions without putting your system at risk. It’s a straightforward, non-indicating fuse—no extras you don’t need, just reliable protection that does its job every time. This is the kind of component you install once and don’t have to think about again.
