Eaton ACK-30 Fuse - Time-delay DC Stud Fuse 130 Vdc
Part Number: ACK-30
Quick Summary
ACK-30 is a time-delay DC stud fuse designed for forklift DC circuits and battery charging applications. It delivers reliable overcurrent protection while minimizing nuisance trips during transient inrush events. In practice, engineers seek protective devices that combine fast response to severe faults with tolerance to normal motor and charger inrush, reducing downtime. While this Eaton Bussmann series device is built for rugged DC protection, verify regional compliance and datasheet guidance for your specific installation. This model delivers a compact, easy-to-install solution that pairs with standard stud mounts and supports efficient inventory management for maintenance teams.

FAQs
The ACK-30 is designed for DC circuits in forklifts and battery charging installations. Its 2.5 inch length and stud-mount design fit standard power distribution blocks, while the 130 Vdc rating accommodates typical forklift and charger supplies. Use with compatible Bussmann series holders and ensure electrical clearances meet your machine’s safety guidelines. The dual-element construction supports robust fault containment across drive and charge circuits.
ACK-30 provides time-delay protection with specific trip characteristics: 100 seconds at 200%, 35 seconds at 300%, and 13 seconds at 500% overcurrent. This behavior tolerates brief inrush and motor starting surges common in charging stations and traction systems, while delivering prompt protection during sustained faults. This balance helps prevent nuisance outages and reduces wear on power conversion equipment.
Yes, the ACK-30 is a one-time fuse, non-indicating by design. After a fault event, the fuse must be replaced rather than reset. This simplifies fault diagnostics and ensures that a known-good component is reintroduced into the circuit. For maintenance planning, stocking standard replacement fuses and documenting fuse locations accelerates repair times and minimizes downtime.
The ACK-30 uses a stud mounting method and ships in standard packaging. For installation, ensure the stud terminals are clean and torqued to manufacturer recommendations, with appropriate cable lugs and insulating spacers as required by the chassis. The compact 2.5 in length and 0.81 in square cross-section allow straightforward integration into crowded DC distribution blocks common in warehouses and industrial vehicles.
Key ratings include a 30 A amperage rating and a 130 Vdc voltage rating, with a time-delay response profile suited for DC loads in forklifts and charging circuitry. The dual-element design enhances fault isolation, while the non-indicating, stud-mounted form factor supports rugged installation in harsh industrial environments. For compliance, always reference the official datasheet for specific regional requirements and integration guidelines.
