Bussmann 170M3214 High Speed Square Body Fuse, Class aR, 160A

Bussmann 170M3214 High Speed Square Body Fuse, Class aR, 160A

The Bussmann 170M3214 is an Eaton Bussmann series high speed square body fuse engineered for semiconductor protection in demanding industrial power circuits. Rated 1250V (IEC) and 1300V (UL) with a 160A rating and a 200 kAIC interrupt rating, this Class aR fuse meets DIN 43 620 blade end x blade end mounting dimensions for direct busbar connection. A top-mounted fuse status indicator provides quick visual confirmation of fuse condition, while the square body design with slotted, center-bolted tags ensures a secure, low-resistance connection in high-current applications.
