Westinghouse 8CLT18 Class CLT Current Limiting Fuse

The Westinghouse 8CLT18 Class CLT current limiting fuse is a high-voltage protective device designed to interrupt fault currents rapidly and provide overcurrent protection at 15,500 V. It carries an 18 A current rating and is mounted as a fuse assembly, commonly installed in switchgear, motor control equipment, and heavy industrial electrical infrastructure, including power distribution systems. Applications cover industrial power distribution and high-voltage protection, with typical installations in switchgear and medium-voltage distribution equipment within manufacturing facilities, substations, MCC systems, utility equipment, and other industrial electrical systems. Manufacturer part number 8CLT18 from Westinghouse, a Class CLT current-limiting fuse, is used for fault current interruption and overcurrent protection; common replacements include Eaton Bussmann CLT-18 Fuse, Littelfuse Medium Voltage Current Limiting Fuse, and Ferraz Shawmut CLT Series Fuse.
