Eaton ACK-70 Fuse - 130 Vdc Time-Delay Stud Mount

Time-delay design with dual elements delivers inrush tolerance and selective fault isolation, preserving motor and charger startup while reducing nuisance trips. The ACK-70 is a 70 A, 130 Vdc fuse with defined trip characteristics—approximately 100 seconds at 200% overload, 35 seconds at 300%, and 13 seconds at 500%—so critical DC circuits stay protected during surge events. This combination shields forklift battery charging circuits and DC distribution lines from overcurrent damage, helping maintain productivity in high-demand warehouse operations. The time-delay feature also mitigates rapid voltage fluctuations common in battery chargers and regenerative braking environments, improving overall system reliability and equipment life. For maintenance teams, using a single, standard fuse reduces diagnostic time and simplifies replacement logistics across fleets. Stud mounting and a compact 3.5 inch length simplify installation in crowded panels and on-vehicle battery compartments. The standard Bussmann series form factor allows straightforward retrofits and reliable compatibility with existing fuse holders, easing procurement and maintenance planning for fleet managers. The 1.063 inch width and 1.063 inch height fit standard automotive and industrial enclosures, while the 3.5 inch depth provides ample room for wire routing and secure termination. Operators appreciate the predictable mounting footprint during panel builds and service work. Non-indicating, dual-element design supports clear fault discrimination while the one-time fuse feature ensures predictable replacements after an event. This configuration minimizes maintenance ambiguity and aligns with safety practices in industrial power systems. In practice, technicians rely on process logs and replacement schedules rather than fragile indicators that can fail in harsh environments. Designed to protect DC power paths in forklift charging stations and battery chargers, the ACK-70 provides consistent response across a wide operating range. By limiting conductor temperatures and safeguarding sensitive controls, it reduces wiring fatigue and extends the life of critical components in heavy-duty automation environments. Overall, the ACK-70 delivers reliable, space-efficient DC protection suitable for high-cycle industrial applications and long-term asset care. Its compatibility with the Bussmann series enhances stocking and cross-compatibility across Eaton protection devices.
