TRS225R - 225 Amp Fuse Description
TRS225R - 225 Amp Fuse
The TRS225R is a 225-amp Class R fuse designed for circuits that need solid protection but can’t afford constant nuisance trips. It’s a time-delay fuse, so it’ll ride through normal startup surges—like motors kicking on—without blowing unnecessarily. At the same time, if there’s a real fault, it reacts fast and helps limit the damage. This fuse is rated 200 kA at 600 VAC, which puts it in the category for higher-fault-current environments. In other words, it’s made for heavier-duty systems where protection actually matters, not light residential use. The knife-blade style provides a secure fit in the right holder, and since it’s non-indicating, there are no extra parts to fail—it’s simple and does what it’s supposed to. It’s the kind of fuse you’ll typically see in commercial or industrial setups where equipment runs hard, and startup loads are part of daily operation.
