Bussmann 170M3462 Fuse

The Bussmann 170M3462 is a high-speed, square‑body semiconductor fuse from Eaton’s Bussmann series, engineered to protect power‑electronics by interrupting fault currents quickly. It is rated 100 A at up to 690 V AC and delivers a 200 kA interrupt rating, making it suitable for fast protection in drives, rectifiers, and power converters. Designed as a compact Size 1, square‑body fuse with Class AR (aR) protection, the 170M3462 is commonly used in AC drives, inverters, and motor‑control circuits where semiconductor devices require reliable overcurrent protection without nuisance tripping. This fuse is listed for IEC high‑speed applications within Eaton’s Bussmann catalog and represents the series’ emphasis on protecting semiconductor devices in demanding industrial power electronics.
