Eaton Specification Sheet - BK/ATL-7-1/2
The 7-1/2A amperage rating provides precise protection for DC loads without nuisance tripping. That precision reduces component wear, minimizes unplanned downtime, and extends fuse life in high-cycle industrial environments. Application: fits motor drives, PLC power rails, sensors, and other low-voltage DC circuits in control panels. In practice, designers appreciate the predictability this rating offers, especially in energy-efficient drives and soft-start configurations where fault currents can spike during transitions. The 32 Vdc voltage rating ensures safe operation within typical industrial DC networks. It helps avoid overvoltage stress and arc faults in distributed I/O and power distribution. The 1 kAIC interrupt rating enables reliable fault current interruption in common panel and bus configurations, reducing damage to harnesses, wiring, and connected components during short-circuits. Non-indicating design reduces visual clutter and avoids misreads in color-coded panel layouts, simplifying maintenance planning when multiple fuse types are used across a system. The zinc fuse element and colored red housing provide fast, reliable operation and immediate visual identification, improving maintenance speed and inventory control. UL Listed and RoHS compliant ensure regulatory alignment and market-ready documentation, easing procurement and audits. Standard packaging of 50 units per pack streamlines stocking and shipping workflows, reinforcing compatibility with common Bussmann blade-fuse installations across OEMs and panel builders.

FAQs
BK/ATL-7-1/2 is designed for standard Bussmann blade-fuse sockets and common panel-fuse housings. It fits typical low-voltage DC circuits found in industrial controls, including PLC power rails, motor drive inputs, and I/O modules. When selecting, ensure a compatible blade-fuse footprint and space within the enclosure to maintain proper clearance and ventilation.
The fuse provides 7-1/2A continuous rating, 32 Vdc operating voltage, and a 1 kAIC interrupt rating. These specs protect DC loads from overcurrent without nuisance trips, support safe operation in typical industrial DC networks, and enable reliable fault interruption during short-circuits, safeguarding wiring and components in control panels.
The BK/ATL-7-1/2 is tailored for DC protection in industrial control environments, with a 32 Vdc rating and 1 kAIC interrupt capability. While it can be used in some automotive DC circuits, its primary design and certification focus are industrial controls and panel-based power distribution, where UL Listed and RoHS compliance are advantageous.
This fuse is UL Listed and RoHS Compliant, providing recognized safety certification and regulatory alignment for global procurement. These certifications support compliance audits, facilitate cross-border deployments, and reassure engineering teams that the component meets industry safety and environmental standards.
With a standard packaging of 50 units per pack, high part availability and quick replacements reduce downtime during maintenance. The non-indicating design and color-coded housing streamline identification, while UL RoHS compliance minimizes regulatory risk. Overall, you gain faster repairs, lower carrying costs, and more predictable maintenance planning.
