ECNR225 - 225Amp Fuse

ECNR225 - 225Amp Fuse

When you’re dealing with electrical systems, there’s no room for guesswork. You need protection that reacts when it should—but doesn’t get in the way when everything is running normally. That’s exactly where the Eaton Edison ECNR225 Fuse comes in.

This 225-amp Class RK5 dual-element time-delay fuse is built for real-world conditions where equipment doesn’t always start cleanly or draw steady power. Motors kick, transformers surge, and machinery pulls heavy inrush currents—and this fuse is designed to handle those moments without nuisance openings. Once things go beyond safe limits, though, it responds fast and decisively to protect your equipment from costly damage.

Think of it as a smart layer of protection sitting quietly in your system—letting normal operations flow while standing ready for fault conditions.
