Eaton ACK-25 Fuse - 130 Vdc Time-delay, Stud-mounted
Part Number: ACK-25
Quick Summary
The ACK-25 fuse is a time-delay, stud-mounted protection device for DC circuits in forklifts and battery chargers. Engineers often face a trade-off between compact form-factor and reliable fault protection, and this fuse addresses that by delivering predictable trip behavior in a small footprint. Note that the provided data does not list formal certifications like CE or IP; verify with Eaton's datasheet for any SIL, CE, or IP ratings that apply to your installation. With a 25 A rating and 130 Vdc capability, it supports fleet electrification while minimizing nuisance outages and electrical stress on charging equipment. This combination translates to reduced maintenance costs, improved uptime, and a clearer path to compliant DC protection in industrial settings.

Eaton Specification Sheet - ACK-25
Feature → Business Impact → Application: The ACK-25 offers time-delay protection with defined response times (100 sec at 200%, 35 sec at 300%, 13 sec at 500%), reducing nuisance trips during startup surges and in-rush currents in battery chargers and DC drives. This improves system availability and extends component life in forklift charging stations and material-handling equipment. The dual-element design provides redundancy within a compact package, supporting safer DC circuits in hostile industrial environments and enabling easier serviceability in fleet operations. Feature → Compatibility → Installation: Stud mounting accommodates standard electrical harnesses used in industrial vehicles, enabling quick, secure installation with minimal hardware changes and compatible with Bussmann-series fuse holders. Application: Ideal for DC protection in forklifts, charging stations, and other high-demand battery systems. Feature → Compliance → Risk management: Time-delay behavior helps meet protection coordination requirements in power-train electronics, reducing the likelihood of cascading faults and easing regulatory risk for fleet operators. Feature → Cost optimization → Maintenance: Standardized packaging and non-indicating operation simplify diagnostics and spare-part logistics, lowering total-cost-of-ownership for maintenance teams.

FAQs
The ACK-25 is designed for stud mounting and is compatible with standard Bussmann-series holders used in DC protection for industrial vehicles. This enables straightforward installation without special adapters, reducing installation time and wiring complexity while ensuring secure electrical contact for reliable protection in forklift charging systems.
The ACK-25 provides a time-delay response with trip profiles of 100 seconds at 200% overload, 35 seconds at 300%, and 13 seconds at 500%. These curves help tolerate short inrush events common in DC charging while providing prompt shutoff during sustained faults, protecting adapters, cables, and the battery without excessive nuisance tripping.
Yes. The ACK-25 is intended for DC protection in forklift battery charging applications, featuring 25 A current rating and 130 Vdc voltage rating, along with a dual-element design that supports reliable protection in demanding industrial environments.
The provided data does not list formal certifications. Verify with Eaton's official datasheet or your local regulatory requirements for certifications such as CE, UL, SIL, or IP ratings to ensure the device meets your facility’s compliance standards before deployment.
The ACK-25’s time-delay characteristics help reduce nuisance trips, lowering downtime. Its standard packaging and non-indicating status simplify diagnostics and spares inventory. Combined with reliable DC protection for chargers and forklifts, this can reduce maintenance costs and extend asset life in fleets and charging stations.
