FAQs
TPS-50L is designed for PCB tab mounting, offering a compact 0.56 in square footprint and a 0.88 in height. This compatibility simplifies integration into compact telecom power distribution boards and data-center edge enclosures, reducing layout complexity and install time. Its non-indicating indicator keeps panel aesthetics clean while delivering reliable protection where space is at a premium.
The TPS-50L is rated for 50 A with a 170 Vdc voltage limit and a 100 kAIC interrupt rating. It is current-limiting and uses a glass-melamine tube with silver-plated brass ferrules, offering fast fault interruption and controlled fault energy. These specs support safe operation in telecom DC power rails and harsh installation environments.
Yes. The TPS-50L carries RoHS compliance and CE marking, ensuring conformity with European environmental and safety standards. This makes it suitable for global telecom projects, including regions with strict regulatory requirements, while helping simplify procurement across multinational sites.
Installers should note the PCB tab mounting, compact footprint, and non-indicating status. Plan for compatible PCB pad geometry and appropriate mechanical clearance. The current-limiting action helps reduce fault energy; ensure correct fuse orientation and secure ferrules for reliable contact. This reduces commissioning time and field maintenance costs in busy telecom racks.
Using the TPS-50L improves equipment readiness by limiting fault currents to safe levels, reducing downstream damage and unplanned downtime. Its RoHS/CE compliance simplifies regulatory risk, while the compact PCB-tab design cuts BOM and installation time. Overall, you gain higher system uptime, lower maintenance costs, and easier cross-border procurement for telecom deployments.
