NCLR450 - 450Amp Fuse

NCLR450 - 450Amp Fuse

The NCLR450 is a 450-amp, Class R fuse with a time-delay design and a 200 kA interrupting rating at 600 VAC. It's made for electrical applications where temporary current surges can happen during normal operation, but overcurrent protection is still required.

This is a current-limiting, cartridge-style fuse with a non-indicating design. It measures 10.38 x 2.54 x 2.54 inches. If you're replacing an existing NCLR450, compare the part number and electrical ratings with the installed fuse and the equipment requirements.

Material Compliance and Certifications

Certification and material-compliance information was not included in the specifications provided for the NCLR450. If your application requires UL, CSA, RoHS, REACH, or another specific certification, verify it against the appropriate product documentation before installation.

Where It Works Best

The NCLR450 is designed for compatible electrical equipment that calls for a 450-amp Class R, time-delay, current-limiting fuse. The time-delay characteristic is useful in applications where brief current increases are expected during normal operation.
