Mersen TR100R Class RK5 Time-Delay Fuse | 100 A, 250 V AC

The Mersen TR100R is a 100-amp, time-delay Class RK5 fuse designed for overcurrent protection in both AC and DC circuits up to 250 volts. It offers high interrupting capacities of 200 kA at 250 VAC and 20 kA at 250 VDC, ensuring safe operation under fault conditions. Its time-delay feature accommodates harmless inrush currents from motors and transformers, preventing nuisance tripping during startups. Constructed with a durable fiberglass-reinforced polyester body and filled with high-grade silica, the TR100R ensures fast arc quenching and dimensional stability in demanding environments. The fuse's rejection-style design prevents incorrect replacements when used with compatible fuse blocks, and its blade terminals facilitate easy clip mounting.
