Eaton BK/GMT-3A GMT Telecommunication Fuse - CE RoHS
Part Number: BK/GMT-3A
Quick Summary
Eaton GMT telecommunication fuse BK/GMT-3A provides fast-acting overcurrent protection for telecom equipment and network interfaces. This compact device helps engineers prevent nuisance trips and equipment damage in dense rack environments. Designed for 125 Vac and 60 Vdc circuits, it delivers reliable interruption at high fault levels while remaining physically small. The fuse carries CE marking and RoHS compliance, aligning with strict industry and environmental standards. By selecting a non-indicating, thermoplastic GMT fuse, you gain predictable protection without visual indicators that can complicate panel aesthetics. For project teams, this means easier sourcing, consistent replacements, and improved uptime across communication infrastructure.
