Overview
The Bussmann ACK-60 is a time-delay (slow-blow) stud-mounted fuse engineered for DC circuit protection in material handling and battery charging equipment. Rated at 60 amperes and 130 Vdc, this Fusetron dual-element fuse is designed to tolerate brief starting currents and motor inrush surges while protecting against genuine overloads and short-circuits. The ACK-60 is widely used in fork lift truck charging systems, battery chargers, and other DC applications where nuisance trips must be avoided.
