TRS90R - 90 Amp Fuse

TRS90R - 90 Amp Fuse

The TRS90R is a 90 amp Class R fuse built for circuits that don’t behave perfectly—like motors or transformers that pull extra current when they start up. Instead of blowing right away, this fuse gives that initial surge a moment to pass. But if there’s a real problem, it reacts fast and cuts the fault. It’s also current-limiting, which helps reduce the amount of damage during a short circuit. That can make a big difference when you’re trying to protect more expensive equipment further down the line. With a 200 kA interrupting rating at 600VAC, this fuse is designed for systems where fault levels can get high. The knife-blade style fits standard Class R fuse holders, and the non-indicating design keeps things simple—nothing extra to fail.
