Eaton Specification Sheet - BK/72A-DUMMY
Compact packaging and ferrule-end connections streamline installation, enabling tighter panel layouts and fewer wiring mistakes in crowded telecom cabinets. By reducing the footprint of each fuse, technicians can route cables more efficiently, improving airflow and serviceability during expansions or routine maintenance. This configuration is particularly advantageous for telecom enclosures, patch panels, and equipment upgrades where space is at a premium and demand for uptime is constant. 1 kAIC interrupt rating at 300 Vdc provides a robust protection margin for telecom power rails, helping prevent damage from short-circuits and surge events. That margin translates into fewer outages, lower repair costs, and safer maintenance windows because protective devices respond decisively to fault currents. The 125 Vac/300 Vdc rating aligns with common telecom and control-circuit standards, ensuring compatibility with existing power interfaces across equipment racks. Non-indicating fuse status keeps panel indicators uncluttered in high-density installations, while the standard packaging ensures consistent handling and stocking across service fleets. Product dimensions of 0.28 in by 0.28 in with a height of 1.86 in and a weight around 0.2 lb support lightweight, modular installation in modular digital and analog telecom systems. These attributes simplify field repacks and reduce spare-part variety. Ferrule-end x ferrule-end connections offer secure, repeatable terminations that resist vibration and thermal cycling common in telecom enclosures. The ferrule design also facilitates quick, tool-free replacements when boards are upgraded or reworked during facility migrations. Combined with a plastic case packaging, it creates a reliable, transport-friendly component for field engineers. Compliance and environmental stewardship are built in, with CE marking and RoHS compliance documented for global markets. The dummy fuse's packaging type Plastic Case and standard configuration fit seamlessly into Eaton Bussmann Type 72 lineups, enabling efficient procurement, consistent bill of materials, and predictable lead times across large-install projects. This translates to lower total cost of ownership for facility managers deploying telecom protection across multiple sites.

FAQs
BK/72A-DUMMY is a dummy fuse from Eaton designed for telecom protection in equipment enclosures and racks. It serves as a non-operating protection component used during testing, configuration changes, or maintenance to preserve circuit integrity without triggering protection during normal operation. It is ideal for telecom enclosures, patch panels, and equipment upgrades where a non-indicating, plug-and-play fuse is advantageous.
The fuse is rated for 125 Vac and 300 Vdc with an interrupt rating of 1 kAIC at 300 Vdc, compatible with ferrule-end terminations. It fits standard packaging and is suitable for telecom power rails and control circuits that require a non-indicating dummy fuse with a compact footprint.
Yes. BK/72A-DUMMY is CE marked and RoHS compliant, ensuring alignment with European safety and environmental standards. This supports regulatory compliance for global deployments and simplifies procurement for customers who must maintain consistent certifications across sites.
Ferrule-end connections provide secure, repeatable terminations that resist vibration and thermal cycling common in telecom enclosures. They enable faster, tool-free maintenance and replacements, reduce wiring errors, and support reliable field service in dense rack environments.
Using BK/72A-DUMMY reduces downtime during testing and maintenance, shortens wiring and assembly times due to ferrule terminations, and lowers spare-part variety by standardizing on a single dummy fuse type. The result is lower total cost of ownership and more predictable lifecycle management across multiple sites.
