Bussmann 170M6012 Industrial High Current Power Fuse

The Bussmann 170M6012 is an industrial high-current power fuse from Eaton’s Bussmann series, designed for fast overcurrent protection in demanding power circuits. This square-body, high‑speed fuse is rated for 800 A and supports up to 690 V AC (IEC) or 700 V AC (UL), making it suitable for heavy industrial electrical installations. It is a bolted‑terminal, 3/80‑series device with a front/top fuse status indicator and a /80 visual indicator, in compliance with DIN 43653. The 170M6012 belongs to the 170M family of high‑speed fuses and is cataloged alongside related variants such as 170M6062 and 170M6112. Its I²t rating for the 800 A version is about 69,500 A²s, reflecting its fault‑clearing energy capacity. Designed for bolt‑on mounting in protection blocks, it delivers reliable protection for high‑current power circuits in industrial electrical installations, coordinating with upstream protection devices to minimize damage from short circuits and overloads. This model is widely used in industrial switchgear and distribution blocks where a robust, fast‑acting fuse with clearly visible status indicators is required.
