Eaton Specification Sheet - ATC-20
Feature: Electrical rating of 32 Vdc, 20 A with a 1 kAIC interrupt rating provides robust protection for DC circuits in control panels. Business impact: Prevents costly faults from propagating through drives and logic circuits, reducing unplanned downtime. Application: Ideal for industrial automation cabinets and DC motor drives where precise protection is required. Feature: Non-indicating fuse design minimizes panel clutter and eliminates false status signals in indicator-heavy enclosures. Business impact: Cuts inspection time and minimizes misreads during audits. Application: Suitable for systems with centralized status monitoring elsewhere in the automation rack. Feature: RoHS compliant and UL Listed certification verify regulatory compliance and safety for global deployments. Business impact: Eases compliance documentation, simplifies cross-border procurement, and lowers risk of non-conformance fines. Application: Suitable for automotive, machine-building, and process automation projects with strict supplier requirements. Feature: Compact footprint—1.63 in length, 1.38 in width, 0.38 in height—combined with a standard blade form factor. Business impact: Enables denser panel layouts and easier retrofits in crowded control cabinets. Application: Perfect for compact industrial controllers and space-constrained automotive control boxes. Feature: Clear cataloging and availability through Eaton’s documentation, including specification sheets and catalogs. Business impact: Streamlines sourcing, reduces lead times, and supports lifecycle cost management. Application: Replacements and spares planning across multiple lines and facilities.

FAQs
ATC-20 is a Bussmann series blade fuse designed for low-voltage DC protection in industrial panels. It carries a 20 A amperage rating, a 32 Vdc voltage rating, and a 1 kAIC interrupt rating. It uses a standard blade form factor compatible with common ATC fuse holders, enabling quick swaps during panel maintenance. When replacing fuses, ensure the holder type matches ATC blade fuses and that the circuit load aligns with the 20 A rating.
The ATC-20 offers a 1 kAIC interrupt rating and a 32 Vdc voltage rating. The 1 kAIC rating indicates the maximum fault current the fuse can safely interrupt without external failure, protecting components and wiring. The 32 Vdc rating defines the maximum continuous operating voltage the fuse tolerates, guiding safe circuit design and preventing insulation breakdown in DC control loops.
Yes. ATC-20 is RoHS compliant, reducing hazardous substances in electronics assemblies, and UL Listed, meeting recognized safety standards. This combination supports global deployment in automotive, industrial, and machinery applications while aiding regulatory documentation, supplier qualification, and market access across regions with strict electrical safety requirements.
Absolutely. The 32 Vdc, 20 A rating and 1 kAIC interrupt capability make ATC-20 suitable for many DC protection scenarios in automotive and industrial environments. Its compact blade form factor and non-indicating design support integration into dense control panels and vehicle electronics where reliable overcurrent protection is essential without adding panel indicators.
Technical specifications and catalogs for ATC-20 are available from Eaton. Look for the ATC-20 specification sheet and Bussmann series catalogs, along with retail product profiles, to verify ratings, dimensions, and compliance notes. Supplementary media such as Fuseology videos can provide installation guidance and applications examples.
