Eaton Specification Sheet - BK/GMT-4A
The GMT-4A fuse is designed with a compact footprint, measuring 0.78 in length, 0.62 in height, and 0.11 in width, weighing 0.1 lb, which frees panel space and supports high-density installations in telecom enclosures. This smaller form factor translates to easier routing and quicker swaps during maintenance, helping technicians reduce downtime in mission-critical networks. The 4 A amperage rating paired with strong interrupt capabilities (300 AIC at 125 Vac and 450 AIC at 60 Vdc) delivers reliable protection against short circuits and overloads, safeguarding power rails and sensitive data equipment while minimizing collateral damage to surrounding components. A 125 Vac / 60 Vdc voltage rating makes BK/GMT-4A suitable for mixed AC/DC telecom applications, enabling versatile use across equipment racks and distribution panels. The fast-acting response quickly clears faults, reducing fault energy and potential arc damage in high-speed telecom systems, which improves overall system reliability. The non-indicating design reduces panel noise and simplifies visual monitoring, while tin-plated beryllium copper terminals ensure excellent contact reliability and corrosion resistance in challenging environments. The thermoplastic housing provides mechanical durability and ease of fabrication, enabling consistent performance over a wide temperature range common in data centers and field deployments. Compliance with CE and RoHS standards further reduces regulatory risk, supporting global deployments and procurement continuity. These features collectively translate into measurable outcomes: lower maintenance costs, fewer unscheduled outages, and streamlined spares management for network operators and OEMs.
