Eaton Specification Sheet - BK/GMT-3/4A
Fast-acting protection is the core feature, delivering rapid fault isolation to minimize damage and downtime. By clearing faults quickly, the fuse reduces arc energy and protects downstream electronics in telecom line cards and network interfaces. With a 0.75 A rating at both 125 Vac and 60 Vdc and high interrupt ratings, this GMT fuse supports sensitive equipment while meeting demanding AIC requirements in data-center racks and remote sites. Non-indicating design eliminates false status readings in dense installations, reducing misinterpretation during maintenance. In telecom cabinets and patch panels, technicians can rely on protection without extra wiring or LED indicators that can fail in harsh environments. The absence of indicators also helps with clean, space-efficient layouts in 19-inch racking. Thermoplastic housing provides mechanical integrity and environmental resistance, while tin-plated beryllium copper terminals offer low contact resistance and corrosion resistance.

FAQs
BK/GMT-3/4A is designed for standard fuse holders used in 19-inch telecom racks. Its compact 0.78 in length, 0.62 in height, and 0.11 in width fit dense panel layouts, while the standard packaging type simplifies stocking. Use appropriate holder and torque values per manufacturer guidelines to maintain reliable contact and avoid terminal over-tightening that could affect performance.
The fuse provides 0.75 A rating with voltage compatibility of 125 Vac and 60 Vdc. It offers interrupt ratings of 300 AIC at 125 Vac and 450 AIC at 60 Vdc, enabling robust short-circuit protection for both AC and DC telecom circuits. This combination supports protection of line cards and network interfaces against fault currents in mixed-supply environments.
Yes. The BK/GMT-3/4A carries CE marking and RoHS compliance, ensuring regulatory readiness for European markets and reducing compliance risk in global deployments. This makes it suitable for telecom equipment, data centers, and field installations where regulatory adherence is critical.
Commonly selected for telecommunications and data-center infrastructure, BK/GMT-3/4A protects telecom line cards, network interfaces, and protection panels. Its fast-acting performance and high AIC ratings make it suitable for remote sites, 19-inch racks, and other environments where reliable circuit protection and quick fault isolation are essential.
The fuse’s non-indicating design reduces maintenance confusion in dense installations, while its durable thermoplastic body and tin-plated terminals enhance reliability and lifecycle performance. Standardized GMT-series compatibility streamlines stocking and procurement, lowering total cost of ownership and minimizing downtime during fault events.
