Eaton Specification Sheet - ATC-40
32 Vdc, 40 A, and 1 kAIC ratings provide fast fault interruption for DC power circuits, protecting wiring and sensitive electronics from overloads. These combined specs reduce the risk of thermal damage and downtime in industrial control panels and automotive power systems. This makes it suitable for automotive power systems and DC distribution networks. Engineering teams value its compatibility with standard DC protection schemes and its predictable trip characteristics. The orange body aids quick identification in dense harnesses. ATC blade fuse geometry in a 0.75 inch length fits standard Eaton Bussmann ATC fuse blocks and holders, enabling quick drop-in replacements without panel redesign. This translates to faster commissioning and lower installation labor in control cabinets and vehicle electrical racks. Its uniform footprint supports multi-location stocking, reducing the risk of mismatches during maintenance. UL Listed certification and RoHS compliance simplify qualification for audits and regulatory reviews. The fuse's formal safety categorization supports customer SI audits and QA processes, while RoHS alignment reduces environmental risk. Having a single, RoHS-compliant SKU across sites minimizes procurement complexity and accelerates vendor handoffs. Non-indicating design reduces diagnostic chatter in high-density panels, making it easier to plan replacements during routine preventive maintenance. Industry professionals frequently specify ATC-40 in machine building, vehicle electronics, and solar DC protection schemes due to its reliable trip performance and broad availability of the Bussmann line. The fuse's orange color facilitates quick identification in bundle harnesses and dense panel rows. For retrofits, ATC-40 offers a familiar, widely available option.

FAQs
ATC-40 uses a standard 0.75 inch blade and ATC holder footprint, ensuring drop-in compatibility with most Eaton Bussmann ATC fuse blocks and panel assemblies. It is designed for DC circuits up to 32 V and up to 40 A, with a 1 kA interrupt rating for fault isolation. Choose matching holder, wiring gauge, and enclosure to maximize reliability.
The ATC-40 is rated at 40 A and 32 Vdc, with a 1 kAIC interrupt rating. This configuration enables rapid fault isolation while protecting conductors and components from overcurrent. The fuse is non-indicating, so rely on diagnostics or indicator fuses for fault location, and ensure proper wire sizing and compatible fuse holders.
Yes, ATC-40 fuses are well-suited for automotive harnesses, control panels, and DC power applications in industrial environments. They combine a compact 0.75 inch form factor with a 32 Vdc rating, aligning with typical automotive and DC distribution needs. Use in clean, shielded enclosures to minimize contamination and ensure reliable replacement.
ATC-40 features UL Listed certification and RoHS compliance, confirming safety performance, environmental responsibility, and regulatory alignment. These certifications support customer audits and QA processes, enable unified procurement, and reduce regulatory risk across multi-site deployments.
To minimize downtime, standardize on the ATC-40 as part of your DC protection strategy; keep a small, labeled inventory of 32 Vdc, 40 A ATC fuses for rapid field replacement. Since these are non-indicating, rely on panel diagnostics or indicator fuses where needed. Use proper tool-free replacement and confirm wiring polarity and holder compatibility to avoid misinsertion. This approach lowers MTTR and reduces spare parts waste.
