Eaton GMT-1A Telecommunication Fuse - CE Marked RoHS Compliant
Part Number: GMT-1A
Quick Summary
GMT-1A telecommunication fuse provides fast-acting overcurrent protection for telecom circuits in data and communications gear. Engineers often struggle to find a protector that responds quickly to faults without triggering nuisance trips in sensitive equipment, especially in compact enclosures. It carries CE Marked and RoHS compliance, aligning with European safety and environmental standards for rugged telecom deployments. The fuse's small form factor, standard packaging, and tin-plated beryllium copper terminals simplify board or panel mounting across multiple chassis. Designed for Eaton's GMT family, it supports streamlined sourcing and consistent performance, helping reduce field downtime and service costs while maintaining compliance across mixed-voltage telecom applications.

Feature: 1 A amperage rating with 125 Vac / 60 Vdc voltage ratings. Business Impact: Protects sensitive telecom rails quickly, reducing arc energy and downstream damage, which minimizes downtime and extends equipment life. Application: Data center power rails and backplanes in network gear where precise overcurrent protection is critical. Feature: Fast-acting, non-indicating design. Business Impact: Delivers reliable protection without visual indicators that can mislead technicians in dense cabinets, lowering replacement costs and simplifying panel labeling. Application: Enclosures with host-side monitoring systems where status is tracked by upstream circuitry. Feature: Tin-plated beryllium copper terminals. Business Impact: Ensures low contact resistance, corrosion resistance, and robust solder/terminal connections for long, maintenance-free service. Application: Panel-mounted fuses in harsh telecom environments. Feature: Gray color code and compact form factor (0.78 in L x 0.62 in H x 0.11 in W). Business Impact: Space-saving design enables higher rack density and easier field replacement, reducing service time during outages. Application: Dense telecom backplanes and small-format power modules. Feature: CE Marked and RoHS compliant. Business Impact: Accelerates regulatory clearance and supplier qualification, reducing time-to-deploy in enterprise networks. Application: Global deployments across telecom, data centers, and service-provider equipment. Insight: The GMT-1A fits seamlessly into the broader GMT family, offering consistent performance characteristics across the line, improving procurement reliability and spare-part planning for field operations.

FAQs
GMT-1A is designed for telecom circuits in data centers, network gear, and backplane assemblies. It uses tin-plated beryllium copper terminals for reliable terminations, with a compact 0.78 in length, suitable for both panel mounting and board-level installations. When replacing, ensure the fuse is seated in a compatible fuse holder and that the rating (1 A, 125 Vac/60 Vdc) matches the circuit requirements.
GMT-1A provides a 1 A amperage rating with voltage ratings of 125 Vac and 60 Vdc. It is fast-acting to interrupt fault currents quickly, while its non-indicating design reduces stand-by visual wear. This makes it suitable for telecom power rails and data-path protections where rapid clearing is essential.
Yes, GMT-1A is rated for 60 Vdc, making it appropriate for DC telecom applications within that limit. It carries CE Marked and RoHS compliance, ensuring alignment with European safety and environmental standards for telecom devices and services.
GMT-1A features CE Marked and RoHS compliance, signaling conformance with European regulatory requirements and restricted hazardous substances. This simplifies vendor qualification, risk management, and cross-border deployments in telecom and data center environments.
As a fast-acting, non-indicating fuse, GMT-1A requires periodic verification that protection is intact and within spec. In dense equipment, plan for replacement during scheduled maintenance or after fault events. The 0.1 lb weight and standard packaging simplify stocking and field swaps, reducing downtime during outages.
