NCLR125 - 125Amp Fuse

NCLR125 - 125Amp Fuse

When your fuse opens, the priority is protecting your equipment and getting it back in service. But choosing a replacement takes more than matching the amperage. Voltage, interrupting capacity, and how the fuse responds to temporary current surges all matter. The NCLR125 125 Amp Class R Time-Delay Fuse combines these key characteristics in a cartridge-style design suited for compatible industrial and commercial electrical systems. Rated at 125 amps and 600V AC, it provides overcurrent protection with a 200 kA interrupting rating at 600V AC, making it suitable for applications that must account for high available fault currents.
