Eaton BK/ATM-20 ATM Blade Fuse - 20 A 32 Vdc 1 kAIC
Part Number: BK/ATM-20
Quick Summary
The Eaton BK/ATM-20 ATM blade fuse protects DC circuits in control panels and power supplies. Engineers face challenges matching fuse ratings to dynamic DC loads, fearing nuisance trips or undersized protection. RoHS compliance is confirmed, and additional approvals can be pursued by request to the factory. This approach helps standardize protection across Eaton Bussmann ATM products, reducing spare-part complexity and improving uptime for industrial automation and distributed power systems.

Feature integrated into the BK/ATM-20 includes a 20 A amperage rating, 32 Vdc voltage rating, and a 1 kAIC interrupt capability, delivering robust protection for low-voltage DC circuits. Business impact: precise overcurrent protection minimizes conductor and device damage, reduces unplanned downtime, and simplifies fault diagnosis in today’s automated lines. Application: ideal for DC power supplies, control cabinets, and motor drives in industrial automation environments, where predictable protection supports uptime and reliability. Feature a blade-end design with a colored plastic housing and color-code, enabling quick identification during maintenance and rapid part replenishment—reducing training time for technicians. Business impact: faster change-outs and fewer mis-parts in spare inventories. Application: common in Bussmann ATM blade fuse blocks and compatible holders, ensuring easy retrofit and scalable protection. Feature non-indicating indicators and standard packaging (500 units per box) streamline installation in densely populated panels, while keeping panel aesthetics clean. Business impact: cleaner wiring harnesses and simplified compliance auditing. Application: suitable for high-density control panels and distributed protection schemes across manufacturing lines. Feature RoHS compliance with factory-provided additional certifications on request ensures regulatory alignment for sanctioned environments. Business impact: supports environmental and supplier compliance programs, easing procurement and audit processes. Application: regulated manufacturing sectors requiring lead-free components. Feature compatibility across the Bussmann ATM family guarantees stock-and-swap efficiency when expanding protection footprint. Business impact: reduces total cost of ownership through part standardization and minimized spare-part variety. Application: large-scale plant protection programs and multi-line deployments.
