FAQs
The ACK-35 is a stud-mounted, dual-element fuse with a 2.5 inch length and standard packaging. It is designed for DC circuits up to 130 Vdc and 35 A, making it straightforward to wire into fork lift controllers and battery chargers. Ensure correct stud terminals and inline wiring, and consult the Eaton datasheet for torque specs and mounting clearances during panel integration.
Key performance features include 35 A amperage rating, 130 Vdc voltage rating, dual-element construction, and a defined time-delay response: 100 seconds at 200% overload, 35 seconds at 300%, and 13 seconds at 500%. It is a non-indicating, standard-packaging fuse suitable for DC protection in heavy equipment.
Yes. The ACK-35 is explicitly designed for DC protection in forklift circuits and battery chargers. Its time-delay characteristics help manage inrush and load transients common in charging cycles, while the stud-mount design facilitates reliable, durable connections in harsh industrial environments.
The provided data does not list specific certifications such as CE or UL. For accurate certification details, refer to Eaton’s official ACK-35 datasheet and catalog pages. Always verify the latest regulatory compliance information during procurement and in your QA documentation before field deployment.
By offering predictable time-delay protection and a robust dual-element design in a compact stud-mounted package, the ACK-35 reduces nuisance trips and protects power wiring and charging circuits. The one-time fuse feature helps prevent bypass, supporting longer interval maintenance and lower replacement costs in fleet charging infrastructure and material-handling equipment.
