FAQs
GMT-3/4A is designed for telecommunications and data equipment protection. It uses a 0.75 A rating with 125 Vac and 60 Vdc limits, and features tin-plated beryllium copper terminals for reliable connections. It fits within the Eaton Bussmann GMT family and is suitable for panel-mounted protection in data centers, network cabinets, and field enclosures.
The GMT-3/4A fuse provides a 0.75 A amperage rating with voltage ratings of 125 Vac and 60 Vdc. It is fast-acting and non-indicating, with a brown color code for quick identification. This combination supports rapid fault interruption while maintaining safe operating margins for telecom power and signal paths.
Yes. GMT-3/4A carries CE marking and RoHS compliance, ensuring regulatory alignment for European markets and other regions that recognize these standards. This supports easier audits, safer disposal practices, and smoother procurement processes when deploying across multiple sites.
Non-indicating fuses do not provide an on-state visual status. For maintenance, plan to use external monitoring or panel indicators to confirm fuse status. This reduces false alarms in busy environments and allows technicians to perform targeted inspections without removing or masking indicators on the fuse itself.
GMT-3/4A measures 0.78 inches in length, 0.62 inches in height, and 0.11 inches in width, with a weight of about 0.1 lb. These compact dimensions enable dense panel layouts and straightforward replacement in existing GMT-based circuits without requiring additional clearance or tooling.
