TRS17.5R - 17½ Amp Fuse

TRS17.5R - 17½ Amp Fuse

When you’re dealing with equipment that pulls a surge at startup, you need a fuse that won’t quit too early. The TRS17.5R is built for exactly that situation. This 17.5 amp Class R time-delay fuse lets temporary inrush currents pass without tripping, but still reacts quickly when there’s a real problem. It’s also designed to limit fault current before it can cause serious damage. With a 200 kA interrupting rating at 600 VAC, it’s more than capable of handling high-fault conditions in demanding systems. The cartridge design keeps things simple, and since it’s non-indicating, there’s nothing extra to worry about—just consistent, dependable protection. This is the kind of fuse you use when downtime isn’t an option and guesswork isn’t acceptable.
