Eaton TPL-BL Telecommunication Fuse - 100 kAIC
Part Number: TPL-BL
Quick Summary
Eaton TPL-BL telecommunication fuse provides reliable DC protection for telecom power systems. Engineers often struggle with nuisance tripping and downtime when protecting DC distribution networks. This device is CE marked and RoHS compliant, aligning with European and global regulatory requirements. With a compact footprint and current-limiting action, it reduces panel size and fault energy without sacrificing protection. Designed for telecom and data-center environments, it supports dependable service in rugged installations while remaining compatible with bolted blade end connections. The non-indicating status means integrated protection schemes must infer health from upstream logic, reducing local indicators in crowded panels. This combination delivers predictable protection, lower maintenance, and improved overall equipment effectiveness for critical DC networks.
