Eaton ACK-225 Fuse - Time-delay Dual Element 80 Vdc
Part Number: ACK-225
Quick Summary
The ACK-225 fuse from Eaton is a time-delay, stud-mounted DC protection device designed for forklift charging and other high-current battery systems. Engineers often contend with nuisance trips during peak charging or surge events, which can drive downtime and maintenance costs. While no explicit certifications are listed for this exact model, it’s important to verify site requirements for SIL, CE, or IP ratings against your local standards and Eaton datasheets. By selecting the correct amperage and voltage rating with a rugged stud-mount design, customers gain reliable protection, easier installation, and reduced overall operating expense in mixed fleet environments.

FAQs
Install the ACK-225 by mounting it on a stud connection using the copper terminal as provided. Ensure secure torque on mounting hardware and verify the circuit is de-energized before installation. Confirm the 80 Vdc rating matches your system and route the conductor to the dual-element fuse body per Eaton guidance for reliable protection.
ACK-225 offers a 225 A rating with an 80 Vdc limit and a time-delay response (100 s at 200%, 35 s at 300%, 13 s at 500%). The dual-element, copper-terminal design provides rugged, fast-acting protection against faults while tolerating inrush, making it well-suited for forklift chargers and other high-current DC loads.
Yes. ACK-225 is part of Eaton Bussmann’s fuse family, with catalog references and datasheets available in the downloads section. For procurement and replacement planning, refer to the ACK-225 specification sheet and Bussmann catalog PDFs to verify dimensions, terminal type, and mounting requirements.
ACK-225 is a non-indicating, one-time fuse, so after a fault or trip, replace it with an identical device to restore protection. Inspect the mounting hardware and copper terminals for corrosion, ensure clean connections, and verify the system is re-energized only after the fuse is correctly seated and rated for 80 Vdc.
Since explicit certifications are not listed for this model, cross-check your site requirements with SIL, CE, and IP standards and confirm with Eaton datasheets. Validate that the 225 A/80 Vdc ratings align with your forklift charging infrastructure, DC power distribution, and any local electrical codes before installation.
