Eaton Specification Sheet - ACL-120
Feature → Business Impact → Application: Non time-delay protection delivers fast response to overcurrent events, reducing damage to power electronics and motor drives while maintaining operational continuity in demanding DC circuits. This translates to lower repair costs and shorter downtime in forklift charging stations and battery rooms. Feature → Business Impact → Application: Dual-element construction increases reliability by sharing fault current and extending fuse life under cycling conditions common in high-load DC systems, helping fleets run longer between replacements. Feature → Business Impact → Application: Stud mounting provides a rugged, vibration-tolerant connection ideal for mobile equipment in warehouses and manufacturing floors, enabling quick, secure installations with minimal cabinet space. Feature → Business Impact → Application: 120 A rating aligns with typical forklift charger and DC circuit protection needs, ensuring protection without triggering from normal startup surges, reducing nuisance trips. Feature → Business Impact → Application: Compact dimensions (2.5 in x 0.56 in x 0.56 in) and light weight simplify retrofits and cabinet layout in industrial settings, supporting cost-effective upgrades. Feature → Business Impact → Application: Compatibility with Bussmann series catalogs and datasheets aids procurement and stocking strategies, enabling standardized spares and faster support. Industry context and practical tips: Validate with Eaton’s ACL-120 datasheet for mounting torque and electrical clearances, and plan preventive maintenance around connector integrity and fuse replacement intervals to optimize uptime.

FAQs
When installing the ACL-120, ensure correct polarity and secure stud terminals with proper torque per Eaton's guidelines. Use the dual-element design for balanced current sharing and verify the 120 A rating matches the charger or motor drive load. Confirm cabinet clearance and secure wiring to minimize vibration and connection wear in warehouse environments.
The ACL-120 is specified as non time-delay, meaning it responds rapidly to overcurrent events to protect conductors and power electronics. Use it for continuous, high-load DC circuits where fast fault interruption is needed but nuisance trips from inrush are unacceptable, such as battery charger protection in forklifts.
Yes. ACL-120 features dual elements for improved reliability and is designed for stud mounting, aligning with Eaton Bussmann’s dual-element product philosophy. This compatibility simplifies stocking and installation within Bussmann series protections and reduces the need for adapters or custom hardware.
ACL-120 is ideal for forklift battery chargers and other DC circuit protections where a robust 120 A protection device is required. Its non time-delay characteristic and dual-element construction support reliable operation under cycling loads common in material handling, warehousing, and heavy equipment charging stations.
Official specifications and datasheets are available from Eaton. Key resources include the ACL-120 specification sheet and the Bussmann catalog PDFs, which provide mounting torque values, electrical ratings, and installation guidance for compliant, durable protection in your DC systems.
