Eaton ACK-200 Fuse - Time-delay Stud-Mount 72 Vdc
Part Number: ACK-200
Quick Summary
The Eaton ACK-200 fuse provides reliable DC protection for forklift power systems and battery chargers. Engineers often contend with nuisance trips and downtime when protecting high-current DC circuits under dynamic load profiles. Certification coverage for such components typically includes CE, UL, and CSA depending on regional requirements; consult the Eaton datasheet for exact certifications. This time-delay, dual-element design uses a copper terminal and stud mounting to support quick, secure installation in standard enclosures. With a 72 Vdc rating and 200 A capacity, it protects wiring and power electronics from overloads while enabling fast, predictable response to faults. Its compact footprint helps simplify integration in crowded electrical bays and minimizes wiring complexity.

Time-delay operation with dual elements provides selective protection for high-current DC feeds. The ACK-200 delivers 200 A at 72 Vdc, tolerating startup surges common to forklift power systems and battery chargers. Its time-delay behavior—100 seconds at 200% overload, 35 seconds at 300%, and 13 seconds at 500%—minimizes nuisance trips while preserving safe, predictable protection during faults. Copper terminals and stud mounting deliver robust electrical contact and secure field installation, supporting quick replacement and reliable connections in standard control panels and battery charging stations. The compact footprint (3.63 in L × 0.56 in W × 0.56 in H) and light weight (0.195 lb) maximize enclosure density and improve thermal performance in crowded industrial spaces. Non-indicating design reduces front-panel complexity, while the one-time fuse feature enforces maintenance discipline and predictable replacement in routine servicing. This combination simplifies integration with Eaton Bussmann series devices and aligns with common hardware in forklift and charging applications, minimizing wiring entropy and installation time.

FAQs
The ACK-200 is a 200 A, 72 Vdc time-delay dual-element fuse designed for DC protection in forklift power systems and battery chargers. It uses a stud mounting with copper terminals, aligning with common heavy-duty busbars and control panels. For retrofits, ensure your enclosure offers adequate space for the 3.63 in length and compatible stud hardware. Always verify terminal sizes and mounting clearances against the Eaton datasheet to ensure a secure, vibration-resistant installation.
The ACK-200 provides time-delay protection with a defined response profile: 100 seconds at 200% overload, 35 seconds at 300%, and 13 seconds at 500%. This means short transients are tolerated, reducing nuisance trips, while sustained faults are cleared quickly to protect wiring, power electronics, and the overall DC network in forklifts and chargers.
The provided data does not specify environmental ratings such as IP or IK protection. For use in harsh environments, consult the Eaton specification sheets (1040 data sheet and related manuals) to confirm environmental suitability, enclosure requirements, and mounting recommendations. In practice, installation within protected housings or control panels is common to shield DC fuses from moisture, dust, and temperature extremes.
Install the ACK-200 using its stud mounting method with a copper terminal, designed for secure, vibration-resistant connections. The fuse is dual-element and laid out for standard enclosures with compatible busbars. Plan for the 3.63 in length and 0.56 in width/height to ensure proper panel fit, adequate clearance for cooling, and straightforward replacement during maintenance cycles. Refer to the official data sheet for exact mounting dimensions and torque specs.
Warranty is listed as Not Applicable in the provided data, so confirm with Eaton for regional policy. From an ROI perspective, the ACK-200’s time-delay design reduces nuisance trips and downtime in high-current DC systems, while the one-time fuse feature supports predictable maintenance planning. The combination of robust protection, compact form factor, and straightforward installation contributes to lower service costs and improved uptime in forklift and battery charging applications.
