Cooper Bussmann 120FEE is a BS88, Type T high-speed fuse with a ceramic, double-barrel body and a 120 A rating designed for circuits up to 690 VAC or 500 VDC (IEC), with UL ratings up to 700 VAC / 500 VDC. It delivers a 200 kA RMS breaking capacity (Symmetrical) and 50 kA DC at 500 VDC, and its 70 mm overall length fits standard BS88 fuse holders. This 120FEE device is part of the Bussmann/Eaton family of high-speed fuses used for semiconductor protection in 690 V systems and high‑current power electronics in industrial controls. The fuse is commonly cataloged as 120FEE and reflects British-standard protection compatible with Type T fuse blocks in electrical distribution panels and motor-drive circuits.
