Bussmann ACK-225 Fusetron Dual-Element Time-Delay Fuse

The Bussmann ACK-225 Fusetron Dual-Element Time-Delay Fuse is a 225 A, 80 VDC dual-element, time-delay fuse in a stud-mounted package designed for DC power protection in demanding applications such as forklift battery systems and battery chargers. This non-indicating fuse uses copper terminals with a stud connection and is part of the Bussmann Fusetron line, offering tolerance for startup surges and short-duration overloads while delivering reliable protection during sustained faults. The ACK-225’s time-current characteristics include about 100 seconds at 200% of rated current, roughly 35 seconds at 300%, and approximately 13 seconds at 500%, enabling close protection of inductive loads like motors and transformers in DC power distributions. This combination of amperage, voltage rating, and dual-element design makes it suitable for high-current DC circuits where inrush is expected, such as forklift power electronics and battery charging systems.
