Eaton BK/GMT-15-X Telecommunication Fuse - RoHS Compliant
Part Number: BK/GMT-15-X
Quick Summary
BK/GMT-15-X Telecommunication fuse provides reliable overcurrent protection for telecom equipment. Engineers often struggle with nuisance trips and compatibility when retrofitting or expanding protection in crowded rack layouts. This GMT series is RoHS compliant, commonly paired with CE-marked equipment for European deployments, and used with IP-rated enclosures in harsh environments; while SIL ratings are not typically applied to small fuses, system safety still benefits from holistic SIL considerations. The compact form and AC/DC voltage rating support space-efficient installations, while the fuse's 15 A rating helps balance protection with uptime. By ensuring compatibility with fuse holders HLT, HLS, and PCT, this device delivers straightforward installation and predictable performance in modern telecom racks.

FAQs
When installing BK/GMT-15-X, verify you are using the proper holder type (HLT, HLS, or PCT) and ensure terminal contacts are clean and secure. Check that the fuse length and mounting allow adequate clearance for heat dissipation. Confirm the circuit’s fault current exceeds the 15 A rating to avoid nuisance trips, and follow standard panel or PCB mounting practices.
The 15 A rating provides a balanced level of protection for typical telecom power draws, while the 125 VAC / 60 VDC rating supports both AC and DC circuits common in telecom gear. For design, ensure the supply voltages do not exceed these ratings, and anticipate inrush behavior. Select fuses to protect equipment without compromising normal operation or uptime.
Yes, BK/GMT-15-X is RoHS compliant, meaning it meets restrictions on hazardous substances used in electronics. This supports regulatory compliance in regions enforcing RoHS, simplifies product stewardship, and eases integration with RoHS-compliant assemblies. Always verify supplier documentation for the latest compliance attestations and cross-check with local regulations for your installation.
Yes, the BK/GMT-15-X is specified for AC/DC use thanks to its 125 VAC / 60 VDC rating and AC/DC designation. When applying to DC circuits, consider longer-term DC fuse characteristics and equipment tolerances. Always verify that the circuit voltage, current profile, and enclosure environment align with the fuse’s specifications.
GMT fuses offer predictable trip behavior with robust reliability, reducing unexpected outages in dense telecom racks. Maintenance involves periodic inspection and timely replacement after fault events, maintaining system protection without overstocking spares. Standardizing on the GMT series with compatible holders (HLT, HLS, PCT) simplifies stocking, service planning, and lifecycle cost management.
