Eaton BK/ACK-60 Fuse - 130 Vdc
Part Number: BK/ACK-60
Quick Summary
The Eaton BK/ACK-60 fuse provides time-delay protection for lift trucks and battery chargers. In high-current DC systems, nuisance trips and difficult replacement can disrupt maintenance schedules and reduce uptime. Note that the data sheet lists no certifications such as CE, SIL, or IP ratings for this unit, which is common for bulk inventory used in industrial power distributions. This compact, stud-mounted device features a brass terminal, dual elements, and silver-plated fuse caps for durable, low-contact resistance connections. Rated at 60 A and 130 Vdc with bulk packaging, it supports fast procurement and consistent field performance in demanding DC power feeds for fleet operations and charging systems.

Eaton Specification Sheet - BK/ACK-60
Feature → Business Impact → Application: Time-delay dual-element design provides improved short-circuit tolerance and arc suppression, reducing nuisance trips and extending component life in lift truck charging circuits. This translates to lower maintenance frequency and higher fleet availability in busy warehouses where downtime is costly. Application: lift truck battery charging and DC power feeds in industrial yards. Feature → Business Impact → Application: Stud-mounted configuration with brass terminals and silver-plated fuse caps delivers robust, corrosion-resistant connections, enabling reliable operation in dusty or humid environments. Application: heavy equipment fleets and mobile charging stations where vibration is routine. Feature → Business Impact → Application: 60 A, 130 Vdc rating supports heavy-duty protection without nuisance tripping during normal peak loads, helping procurement standardize on a single protective device. Application: large forklift garages and manufacturing lines requiring consistent DC protection. Feature → Business Impact → Application: Bulk packaging (100 pieces) reduces total cost of ownership and simplifies stocking for maintenance teams, improving reorder efficiency. Application: fleet deployment and multi-site maintenance programs. Feature → Business Impact → Application: Non-indicating fuse type minimizes visual indicators that could mislead in complex power distributions; this simplifies compatibility with centralized fault diagnostics. Application: integrated protection schemes in battery chargers and DC distribution blocks.

FAQs
Install the BK/ACK-60 using a stud-mounted connection to the DC circuit, ensuring the brass terminal aligns with the existing stud spacing. Tighten to the manufacturer’s torque specification and verify a clean, corrosion-free contact. The fuse’s dual-element design provides reliable protection while allowing for continued operation during transient surges.
The BK/ACK-60 responds in approximately 100 seconds at 200% overload, 35 seconds at 300%, and 13 seconds at 500%. This time-delay behavior helps prevent nuisance trips during normal startup surges while still protecting the circuit from damaging faults in lift truck charging and related DC power feeds.
Yes. The BK/ACK-60 features a dual-element design that delivers arc suppression and enhanced fault tolerance, which is well-suited for lift-truck charging circuits where steady current, short-term spikes, and environmental vibration are common. It’s a robust choice for fleet maintenance programs seeking reliable protection with straightforward replacement.
The product data provided lists certifications as Not Applicable. For projects requiring formal CE, SIL, or IP compliance, verify with Eaton’s latest datasheets or contact a regional representative to confirm any updated certification status or alternative approved parts for your application.
By standardizing on a bulk-packaged, time-delay, dual-element fuse with a 60 A/130 Vdc rating, maintenance teams see reduced stocking diversity, fewer field faults, and faster replacement times. The durable brass terminals and silver-plated caps enhance reliability in harsh industrial environments, delivering lower downtime and improved uptime for fleet operations.
