TRS500R - 500 Amp Fuse

TRS500R - 500 Amp Fuse

The TRS500R is a 500 amp Class R fuse used in systems that carry a lot of load. It’s meant for setups where startup current is high—like motors or larger equipment—and you don’t want the fuse opening every time things kick on. It has a time-delay, so it’ll ride through normal surges. When there’s an actual fault, it clears it fast and limits the current so you’re not dealing with bigger damage further down the line. It’s rated 200 kA at 600VAC, so it’s suitable for systems where available fault current is high. This one uses a knife-blade style connection. Installs solid, nothing complicated. It’s also non-indicating—no window or flag—just a straightforward fuse.
