Eaton Specification Sheet - GMT-4A
Feature: The GMT-4A is rated at 4 A with a voltage rating of 125 Vac and 60 Vdc. This precise current rating minimizes nuisance trips while protecting the most sensitive telecom power rails, resulting in improved uptime for critical network devices. Application: suitable for telecom line cards, small control cabinets, and network equipment where compact, reliable overcurrent protection is required. Business impact: reduces downtime and maintenance costs by preventing collateral damage from overcurrent events. Feature: Fast-acting fuse design delivers rapid interruption when overcurrent occurs. Business impact: minimizes arc duration and protects adjacent components in power distribution networks. Application: ideal for high-speed protection on telecom backplanes and router power inputs. Feature: Non-indicating status with color code white/brown for quick identification. Business impact: simplifies maintenance and reduces field replacement errors. Application: panel assemblies and cabinet enclosures in data centers. Feature: Tin-plated beryllium copper terminals provide robust, corrosion-resistant contacts. Business impact: enhances reliability in humid or vibration-prone environments, extending service life. Application: deployed across controlled racks and field installations where reliability matters. Feature: Compact form factor and standard packaging save panel space. Business impact: enables denser layouts and easier retrofits in existing cabinets, improving installation efficiency. Application: dense telecom panels, control cabinets, and compact network enclosures. Feature: CE Marked and RoHS compliant ensures regulatory alignment for international deployments. Business impact: accelerates procurement and compliance verification across global sites. Application: cross-market telecom infrastructure projects and integrated control systems.

FAQs
To install GMT-4A, mount the fuse in a standard fuse holder or panel with compatible terminals and ensure correct polarity where applicable. The device uses tin-plated beryllium copper terminals for reliable contact, and its non-indicating design reduces panel clutter. Verify the 4 A rating and the 125 Vac / 60 Vdc voltage limits align with your system rails to ensure proper protection.
GMT-4A is rated for 4 A with voltage ratings of 125 Vac and 60 Vdc. It is best deployed in telecom equipment, small control cabinets, and network gear where fast-acting overcurrent protection is required without impacting surrounding circuits. Its CE RoHS compliance supports international deployments and regulatory alignment.
GMT-4A is part of Eaton's Bussmann series and is designed for standard telecommunication fuse applications. It fits typical fuse holders used in telecom panels and control cabinets. When integrating with existing installations, verify terminal compatibility, ensure the standard packaging type, and confirm the non-indicating feature aligns with your maintenance workflows to avoid misinterpretation during service.
Yes. GMT-4A is CE marked and RoHS compliant, confirming adherence to European regulatory requirements and environmental standards. This makes it suitable for international deployments in telecom infrastructure, data centers, and control systems where regulatory compliance and environmental considerations are important for procurement and audit trails.
The GMT-4A provides reliable, fast-acting protection with a compact footprint, reducing downtime from overcurrent faults and enabling denser panel layouts. Its non-indicating design lowers visual clutter, while corrosion-resistant terminals improve long-term reliability in challenging environments. The result is lower maintenance costs, fewer unexpected outages, and improved overall network availability.
