Eaton Specification Sheet - BK/74D-10
60 V and 10 A fast-acting ratings deliver precise overcurrent protection for telecom power rails, minimizing arc flash risk and rapid interrupt times. By curbing fault energy quickly, the BK/74D-10 protects critical equipment such as modems, line cards, and remote terminal units. In practice, engineers see fewer unexpected outages and longer service life in data-center edge devices and network infrastructure. The non-indicating design reduces visual noise inside control cabinets, helping maintain clean panel indicators and easier routine testing. This also minimizes potential misreads during diagnostics, enabling technicians to focus on actual faults rather than indicators. For projects with stringent uptime requirements, this simplicity speeds replacement during maintenance windows. With dimensions of 1.62 in length, 0.42 in width, and 2.4 in height, the BK/74D-10 fits tight telecom enclosures without sacrificing protection. The compact footprint supports high-density panels, where every inch of space matters for thermal management and cable routing. Weight at roughly 0.5 lb aids field handling and reduces inventory weight on service calls. CE Marked compliance provides regulatory assurance for European sites and aligns with international safety expectations for telecom protection devices. Standard packaging and the Bussmann series lineage simplify procurement, cross-referencing, and stocking alongside other Eaton protection products. The device’s documented datasheets and catalog references further streamline spec verification during design reviews. Access to Eaton’s specifications and official catalogs minimizes sourcing risk by giving engineers exact part numbers for BOMs and spares. If a replacement fuse is needed, the BK/74D-10’s compatible cataloging reduces lead times and accelerates maintenance schedules. In practice, teams report smoother audits and lower total cost of ownership when standardizing on Bussmann series fast-acting fuses.

FAQs
The BK/74D-10 is designed for telecom protection applications with a 60 V / 10 A fast-acting profile and non-indicating operation. It fits standard Bussmann series protection schemes and can be substituted in panels that require Eaton telecommunication fuses. Ensure the mounting footprint and lead terminations match your enclosure requirements and that you verify catalog numbers in the official Eaton datasheets.
The BK/74D-10 fuse provides a 60 V voltage rating and a 10 A current rating. It operates as a fast-acting device and is non-indicating, meaning it does not provide an optical fault indicator. These ratings are suitable for protecting telecom data lines and network equipment, with CE marking indicating European safety standard compliance.
Yes, BK/74D-10 is specifically intended for telecom protection. Its fast-acting behavior limits fault energy quickly, reducing damage to downstream devices such as modems and line cards. The compact form factor supports dense panel layouts, and the standard packaging aids in stocking and maintenance planning for telecom cabinets and network racks.
BK/74D-10 carries CE Marked compliance, aligning with European safety standards. This certification supports regulatory acceptance for European deployments and procurement. For projects requiring additional certifications, consult Eaton’s datasheets and regional standards documentation to confirm any site-specific requirements.
Using BK/74D-10 can lower maintenance downtime by delivering predictable, fast fault clearance, reducing unplanned outages. The non-indicating design minimizes panel clutter, while standard catalog references simplify sourcing and BOM creation. Together, these factors shorten repair cycles, improve uptime, and can reduce total cost of ownership over the equipment’s lifecycle.
