Bussmann 170M-360 Series High Speed Square Body Fuse, Class aR, 700V

Bussmann 170M-360 Series High Speed Square Body Fuse, Class aR, 700V

The Bussmann 170M-360 Series High Speed Square Body Fuse, engineered by Eaton, is a Class aR utilization-category fuse built for accompanied semiconductor protection in demanding industrial and power-electronics circuits. Rated 700V (UL) / 690V (IEC) with a 200 kAIC interrupt rating, this square body fuse features center bolted tags and a blade end X blade end connection for secure, high-speed termination. The 170M-360 platform spans a wide amperage range from 40A to 630A, letting engineers match protection precisely to the load while keeping the same proven body style and connection type across every rating.

Key Features

• Amp Rating Range: Available from 40A to 630A across the 170M-360 platform, covering a broad span of circuit protection needs on a single fuse family.
• Dual Voltage Rating: Rated 700V (UL) and 690V (IEC), supporting installations governed by either UL or IEC standards.
