NCLR7 - 7 Amp Fuse

NCLR7 - 7 Amp Fuse

When you're replacing a fuse, the details matter. The NCLR7 is a 7-amp, Class R time-delay fuse rated for 600 VAC, with a 200 kA interrupting rating. It uses a compact cartridge-style design and is current-limiting, making it a good fit for electrical equipment designed around these specific fuse requirements.

Size is straightforward, too. The NCLR7 measures 2 inches long and 0.56 inches wide by 0.56 inches deep, so it's easy to compare the physical dimensions with the fuse you're replacing. It's also a non-indicating fuse, meaning there's no built-in visual indicator to show when the fuse has opened.

If you're replacing an existing NCLR7, or your equipment specifically calls for a 7A Class R, 600V time-delay fuse, check these key specifications before installation.

Material Compliance and Certifications

The supplied specifications don't list material-compliance information or agency certifications for the NCLR7. Rather than assume a certification, verify the markings or documentation for the actual fuse when UL, CSA, RoHS, REACH, or another specific standard is required.

Where It Works Best

The NCLR7 is intended for electrical equipment that calls for a 7-amp Class R time-delay, current-limiting cartridge fuse with the corresponding voltage and interrupting ratings. The time-delay characteristic can be useful in compatible equipment that experiences a brief current increase at startup.

For replacement applications, compare more than the amperage alone. Before installation, check the fuse class, voltage rating, time-delay characteristic, interrupting rating, and physical dimensions against the equipment's requirements.
