Bussmann KTS-80 Fuse

The Bussmann LIMITRON KTS-R-80 is an 80 A, 600 V class RK1 fast-acting, current-limiting fuse designed to protect circuits by interrupting faults quickly. The cartridge-style device uses a ceramic bolt-mount cartridge with 70/30 brass endcaps and is rated for 600 VAC operation and 300 V DC, making it suitable for high-voltage electrical systems. It carries interrupting ratings up to 200 kA at 600 VAC and 100 kA at 250 VDC, enabling it to withstand substantial surge conditions without arcing. As part of the LIMITRON family, it provides fast, reliable protection for power distribution, motor drives, inverters, and other equipment where short-circuit protection matters. The model is commonly listed as KTS-R-80 and is used in industrial controls and electrical panels that require RK1 fast-acting fusing.
