FAQs

BK/GMT-1/4A is a fast-acting GMT telecommunication fuse designed for telecom power feeds. It provides precise protection with a 0.25 A rating and 125 Vac / 60 Vdc voltage ratings, reducing nuisance trips in dense equipment cabinets. The thermoplastic body and tin-plated terminals ensure reliable terminations in data centers and field installations.
The fuse offers 300 AIC at 125 Vac and 450 AIC at 60 Vdc, accommodating fault currents typical in telecom racks. This enables selective coordination with upstream protection devices, helping maintain uptime by isolating faults without affecting adjacent circuits and preserving service levels in critical networks.
Yes. The fuse is CE marked and RoHS compliant, aligning with international environmental and safety standards. This simplifies procurement for global deployments, supports regulatory compliance across data centers, telecom closets, and industrial automation environments, and reduces regional sourcing complexity.
The fuse has a compact footprint: 0.78 inches long, 0.62 inches high, and 0.11 inches wide, with tin-plated beryllium copper terminals. The non-indicating design reduces panel clutter, making it easy to fit in tight telecom racks, distribution blocks, and standard chassis enclosures.
GMT fuses improve uptime by delivering fast fault isolation and protecting sensitive circuits, reducing service interruptions. Their small size and standard packaging simplify stocking and procurement, lowering inventory costs, accelerating project timelines, and enabling consistent protection across multiple sites.
