Eaton BK/ATM-4 ATM blade fuse - 1 kAIC protection
Part Number: BK/ATM-4
Quick Summary
The Eaton BK/ATM-4 ATM blade fuse is a compact overcurrent protection device designed for 32 Vdc automotive and industrial control circuits. Engineers often struggle to fit reliable protection in tight control panels without sacrificing interrupt performance. RoHS compliant and engineered for a 1 kAIC interrupt capability at 32 Vdc, this fuse helps meet stringent safety and regulatory expectations. The pink color code and colored plastic housing simplify quick identification during maintenance, while its 4 A rating provides dependable protection against nuisance trips in standard control loops. For procurement, bulk availability (500 pieces) supports scalable stocking and consistent performance across multiple production lines, reducing downtime and component misselection in high-mix automation environments.

Eaton Specification Sheet - BK/ATM-4
Feature: compact ATM blade fuse with a blade-end design fits in crowded panels and ATM fuse holders. Business Impact: enables faster installations, reduces panel depth requirements, and lowers risk of mis-seating during service. Application: ideal for space-constrained control cabinets in machinery and packaging lines. Feature: 32 Vdc voltage rating with a 4 A amperage rating provides precise protection for low-voltage control circuits, improving uptime and preventing nuisance trips in conveyor, pump, and I/O networks. Feature: 1 kAIC interrupt rating enhances fault containment for automotive and industrial controllers, reducing collateral damage in short-circuit events. Feature: pink color code and colored housing support rapid visual verification of circuit protection, speeding maintenance in high-velocity lines. Feature: RoHS compliance and standard packaging (500 pieces) streamline compliance and procurement for OEMs and panel builders, lowering total cost of ownership through reduced stockouts and safer handling in assembly areas. Feature: non-indicating fuse indicator avoids false positives in lighted panels while maintaining clear protection status in non-illuminated environments, supporting reliable fault diagnostics and service planning.

FAQs
Yes. BK/ATM-4 uses a blade-end design compatible with standard ATM fuse holders, enabling quick drops into control panels, power distribution blocks, and compact automation enclosures. It is particularly beneficial for space-constrained machinery where a small footprint and reliable protection are required, such as packaging lines and conveyor systems.
BK/ATM-4 is rated at 4 A and 32 Vdc with a 1 kAIC interrupt rating. This means it will reliably interrupt fault currents up to 1 kiloamp at 32 volts, protecting low-voltage control circuits and preventing damage to relays, PLC I/O, and small motors in typical industrial applications.
Yes, the BK/ATM-4 is RoHS compliant. Compliance details are available from Eaton's datasheets and product catalogs; the fuse is designed to meet restricted substances requirements, helping ensure regulatory alignment in many regions and simplifying supplier qualification for OEMs.
Ensure to use the correct ATM blade fuse holder designed for BK/ATM-4, verify clean blade contacts, and maintain proper seating to avoid arcing. The pink color code aids quick identification in multi-fuse panels, while the 4 A rating should match the circuit’s normal operating current to prevent nuisance trips.
Bulk packaging (500 pieces) reduces reorder frequency and simplifies supply chain logistics for high-volume assemblies. This improves uptime by minimizing stockouts in manufacturing and service environments, while standardization with Eaton Bussmann series enhances maintenance efficiency and reduces training time for technicians.
