FAQs
TPN-15 is designed for use with Bussmann series telecom fuse blocks and standard DC distribution layouts compatible with TPN fuses. To install, ensure the circuit is de-energized, insert the fuse end-to-end into the holder until fully seated, and verify the 170 Vdc rating and 15 A operation are suitable for the circuit. Use proper terminal engagement and verify tight connections per installer guidelines.
TPN-15 provides a 100 kAIC interrupt rating and a voltage rating of 170 Vdc. These specifications indicate strong fast-acting protection for high-energy DC telecom circuits, helping limit fault energy and protect downstream equipment in telecom power distribution and DC networks.
Yes. The TPN-15 is purpose-built as a telecommunication fuse with current-limiting protection suitable for DC distribution in telecom power supplies and equipment racks. Its 15 A rating and 170 Vdc capability align with typical data-center telecom DC paths, offering reliable fault protection and uptime support in dense installations.
Certification details are not listed in the provided data. For authoritative CE, UL, IP, or other standards, refer to Eaton’s official specification sheets or contact Eaton support to obtain current certification status and scope for the TPN-15 fuse.
The non-indicating design reduces visual indicators in busy panels, while current-limiting minimizes energy let-through during faults, lowering downstream damage and maintenance needs. In practice, this translates to reduced downtime, extended life for DC power components, and improved spare-part readiness in telecom deployments, contributing to a favorable total cost of ownership.
