Eaton ACK-75 Fuse - Time-Delay DC Stud-Mount, 75A, 130 Vdc
Part Number: ACK-75
Quick Summary
The Eaton ACK-75 fuse provides time-delay DC protection for forklift battery chargers and similar DC circuits. Maintenance teams often wrestle with nuisance trips and undersized protection that disrupt schedules and raise repair costs. Although the data here lists no explicit SIL, CE, or IP ratings, the ACK fuse family generally aligns with widely adopted industry standards; verify exact certifications on Eaton's datasheets for your facility. This dual-element, stud-mounted design supports high-current DC networks and contributes to safer, more reliable forklift charging and battery-management operations. By combining robust protection with straightforward installation, the ACK-75 helps engineering teams meet uptime targets and reduce total cost of ownership.

Eaton Specification Sheet - ACK-75
Feature: Time-delay, dual-element construction enables selective fault clearing and tolerates inrush currents typical of forklift battery chargers. This translates to reduced nuisance trips and maintenance costs while preserving critical DC protection in high-current circuits. Feature: Stud mounting and compact form factor with 3.5 in length and 1.063 in cross-section, rated at 75 A and 130 Vdc. This simplifies installation in crowded panels and minimizes wiring, improving reliability of DC power distribution in industrial fleets. Feature: Non-indicating, standard packaging and a one-time fuse design mean lower component costs and clear fault signaling at the point of failure. Feature: Compatibility with Bussmann series ACK family ensures predictable interchangeability and fast field replacement in current install bases. Industry context: In warehouse and manufacturing environments, these attributes combine to deliver uptime, safety, and long-term cost efficiency for DC protection schemes.

FAQs
The ACK-75 uses a stud-mounting method designed for straightforward installation in DC power paths. Begin by disconnecting power, verify voltage in the circuit, and remove the mounting hardware. Align the fuse terminals with the stud posts, tighten to the manufacturer's torque specification, and re-verify continuity. This approach minimizes contact resistance and reduces the risk of arcing while ensuring reliable protection for forklift chargers and similar DC loads.
The ACK-75 provides time-delay protection suitable for DC charging applications. It responds with a measured delay to protect against short surges while avoiding nuisance tripping during normal inrush events. In forklift charging scenarios, this means improved uptime, reduced maintenance interventions, and safer fault clearing without compromising protection for the battery management system.
Yes. The ACK-75 is part of the Bussmann series and is designed for consistent compatibility with standard Bussmann/Eaton mounting practices, including dual-element, stud-mounted configurations. When replacing or upgrading, verify catalog numbers and mounting hardware to ensure a seamless fit, minimal downtime, and verified electrical performance in DC protection layouts for industrial fleets.
This listing does not specify SIL, CE, or IP certifications. For regulated facilities, consult Eaton’s official datasheets and your local electrical standards to confirm exact certifications and compliance marks. In practice, confirm CE/IEC equivalents and safety ratings with the current product documentation to ensure alignment with your facility’s regulatory requirements.
Deploying the ACK-75 can reduce downtime by preventing nuisance trips while maintaining robust DC protection for forklift chargers and similar loads. Its time-delay design, dual-element construction, and easy stud-mount installation contribute to lower maintenance labor, fewer unexpected failures, and improved equipment availability, delivering a favorable total cost of ownership in warehouse and manufacturing environments.
