Bussmann KTU800 Fuse Accessories Bussmann KTU800

The Bussmann KTU-800 is a high-current LIMITRON Class L fuse designed for fast-acting protection of large-load circuits in industrial power distribution and control equipment, rated for 800 amperes and suitable for installations up to 600 VAC (340 VDC). This bolt-on fuse uses a glass-melamine tube and silver-plated end bells, delivering robust electrical and mechanical performance with a stated interrupting rating of 200 kA RMS to clear faults quickly and protect upstream hardware. As part of Eaton’s Bussmann family, the KTU-800 is a fast-acting, current-limiting device intended for high-inrush environments such as motor drives, transformers, and large power panels, where reliable, rapid fault clearing is essential. The device is cataloged as a Class L LIMITRON fuse, reinforcing its role in providing precise overcurrent protection in low-voltage systems while supporting bolt-on mounting with compatible holders. With its 800 A rating and 600 VAC / 340 V DC capability, the KTU-800 is positioned as a main or feeder protection fuse for robust industrial installations requiring high current handling and fast interruption; typical applications include feeders to large loads, switchgear assemblies, and motor-control centers where protection against short circuits and overloads is critical.
