Eaton BK/ATC-3 ATC blade fuse, 32 Vdc, 3 A - 1 kAIC
Part Number: BK/ATC-3
Quick Summary
ATC blade fuse from Eaton delivers fast, reliable overcurrent protection for automotive and industrial control circuits. In compact control panels, selecting the wrong rating or a mismatched fuse can cause nuisance trips and unplanned downtime. This unit carries RoHS compliance to support regulatory requirements in modern electronics manufacturing. The violet color code, non-indicating indicator, and blade-end design simplify field installation, inventory management, and visual inspection for service technicians. BK/ATC-3 combines a 32 Vdc rating with a 3 A rating and a 1 kAIC interrupt rating to protect sensitive circuits without sacrificing performance. This makes it suitable for quick procurement and reliable replacement in both OEM assemblies and maintenance operations.

FAQs
BK/ATC-3 is a blade fuse designed for standard 32 Vdc circuits with a 3 A rating and a 1 kAIC interrupt rating. It fits common blade-fuse holders and is compatible with compact automotive and industrial panels. Its compact dimensions (0.76 in x 0.752 in x 0.207 in) help maximize available enclosure space while maintaining reliable protection.
Install BK/ATC-3 in a properly rated blade-fuse holder using a clean, dry environment. Ensure correct orientation to the holder’s blade contacts and verify seating to avoid poor contact resistance. Since this fuse is non-indicating, use an external panel indicator or monitoring scheme to confirm fuse status during operation.
The 1 kAIC interrupt rating means the fuse can safely interrupt a short-circuit current up to 1 kiloampere at its rated voltage without arcing. This provides robust protection for circuits in lower voltage automotive and industrial installations, helping to prevent collateral damage to wiring and components during faults.
BK/ATC-3 carries RoHS compliance, supporting regulatory requirements for modern electronics manufacturing. While UL or CE markings aren’t listed in the provided data, RoHS compliance helps meet environmental standards and supplier qualification criteria for many OEMs and contract manufacturers.
With a bulk quantity of 2000 units, BK/ATC-3 supports bulk procurement for OEM factories and service fleets, reducing downtime from component shortages. Its standardized dimensions, color coding, and compatibility with common blade fuse holders simplify stocking, replacement, and repairs in both production and maintenance environments.
