Eaton ACK-150 Fuse - Time-delay, 72 Vdc
Part Number: ACK-150
Quick Summary
The Eaton ACK-150 fuse protects DC circuits in forklift power systems and battery chargers with time-delay protection for dependable operation. This approach helps prevent nuisance trips during inrush or motor start, reducing unplanned downtime and maintenance costs. While many DC protection options require complex integration, the ACK-150 offers a straightforward stud-mounted solution with dual elements for enhanced reliability. For engineers and procurement teams, selecting a time-delay fuse that handles brief overloads without compromising protection is critical. In practice, this fuse aligns with typical forklift and industrial DC power architectures, delivering robust fault containment while supporting efficient service and replacement planning. Consider compatibility with 72 Vdc systems and the Bussmann ACK series for streamlined spares management and lifecycle planning.

Feature → Business Impact → Application: Time-delay protection allows the ACK-150 to absorb short-lived surges without tripping, reducing unnecessary downtime in forklift and battery charger applications. This translates to improved equipment availability and smoother shift operations in material handling environments. Feature → Application: Dual-element design provides balanced protection across circuit paths, increasing reliability in demanding industrial DC buses and minimizing the risk of intermittent faults during peak load. Feature → Business Impact → Application: Stud mounting and copper terminals enable solid electrical connections and straightforward installation in rugged industrial enclosures, enhancing vibration resistance and simplifying field maintenance for service teams. Feature → Application: 72 Vdc rating aligns with common forklift and battery charging architectures, enabling direct compatibility with existing DC power distribution while preserving system protection. Feature → Business Impact → Application: Time-delay performance data (100 sec at 200%, 35 sec at 300%, 13 sec at 500%) provides predictable fault response, supporting precise coordination with control logic and adjacent protective devices. Feature → Application: One-time fuse and non-indicating design reduce spare part complexity, while prompting compatibility with external indicators or status monitoring strategies. Feature → Business Impact → Application: Copper terminals and standard packaging streamline procurement and inventory management, enabling faster replacement cycles and reduced downtime during field service. Addressing objections: for systems requiring visible indication, pair the ACK-150 with an external fault indicator; for high-vibration environments, ensure secure mounting and appropriate connector hardware; and for data-driven maintenance, log fuse events via the control system to improve MTBF planning.

FAQs
Install the ACK-150 as a stud-mounted fuse using the copper terminal connections specified by Eaton. Ensure the system is de-energized, mount securely to resist vibration, and align with the 72 Vdc DC bus. Refer to the Eaton installation guide and the ACK-150 datasheet for torque recommendations and wiring diagrams to ensure a reliable, code-compliant fit.
Yes. The ACK-150 is designed for DC circuits in forklift power systems and battery chargers, featuring a 150 A rating and 72 Vdc operating voltage. Its dual-element, time-delay design helps manage inrush currents during charging cycles, reducing nuisance trips while maintaining robust overcurrent protection for industrial charging stations.
The ACK-150 provides 150 A amperage rating and a 72 Vdc voltage rating. Its response times are 100 seconds at 200% overload, 35 seconds at 300%, and 13 seconds at 500%. This combination supports controlled fault clearing in DC power systems without overreacting to brief transients common in motor starts and charging events.
The provided data indicates ‘Not Applicable’ for general compliances. When selecting for regulated environments, verify the exact certifications on Eaton’s official datasheet or contact Eaton technical support to confirm CE, UL, or IP ratings for your region and application.
The ACK-150 is a one-time fuse with a non-indicating status. After a fault or disruption, the fuse must be replaced rather than reset. Plan for spare fuses aligned with your maintenance schedule, and consider external fault indicators if a visual status is required in your control room or dashboard for rapid fault diagnosis.
