TRS3R - 3 Amp Fuse

TRS3R - 3 Amp Fuse

The TRS3R is a 3 amp Class R fuse used for basic circuit protection where you don’t want it blowing every time something starts up. It’s a time-delay type, so it’ll ride through short inrush currents but still open when there’s an actual problem. It’s also current-limiting, which helps reduce the amount of fault energy passing through the circuit. That matters if you’re trying to protect downstream components from getting hit too hard during a short. Rated 200 kA at 600VAC, so it’s fine for higher fault current setups. Standard cartridge style. No indicator. Nothing fancy—just a dependable fuse that fits and works like it should.
