Ferraz Shawmut Class RK5 Time-Delay Blade Fuse; 250 Amp, 600 Volt AC/DC

The Ferraz Shawmut Tri-OniC TRS Series Class RK5 time-delay fuse is designed for industrial circuit protection, rated at 250 Amps for both 600 VAC/600 VDC applications. This fuse ensures reliable operation with its high interrupt rating of 200 Kilo-Amps (AC) and 20 Kilo-Amps (DC). Constructed with a fiberglass body, it offers stability and durability, even in challenging environments. The fuse features high-grade silica filler for fast arc quenching and effective current limitation. Its time-delay function is ideal for motor start-ups and transformer inrush currents, avoiding unnecessary tripping during these common events.
