FAQs
Install the 74A-1-1/4 in standard Bussmann Type 74 footprints within telecom panels or enclosures. Verify that the circuit operating current does not exceed 1.25 A and ensure adequate ventilation and clearance around the fuse to prevent overheating. Use the standard packaging to support quick replacements and minimize downtime during maintenance.
The fuse provides a 1.25 A amperage rating and a 60 V DC voltage rating, with fast-acting operation for rapid fault interruption. It is non-indicating, cylindrical in form, and designed for telecom circuits, offering precise protection without indicator bulbs that can fail in harsh environments.
Yes, the 74A-1-1/4 is suitable for telecom data paths and patch panels operating at 60 V DC. Its fast-acting trip helps limit fault exposure to sensitive line cards and servers, while its compact cylindrical design supports dense, high-density installations common in data center cabinets.
The fuse is CE Marked, signaling conformity with European safety standards. No additional certifications are listed in the provided data, so confirm project-specific regulatory requirements with your compliance team or Eaton datasheets for any regional needs beyond CE.
Using a 74A-1-1/4 fuse standardizes protection across telecom gear, reducing unplanned downtime and spare-part variance. Its documented ratings simplify stocking and replacements, improving panel uptime and operational readiness, while the non-indicating design minimizes potential false indicators in rugged installations.
