Eaton TPS-30LB Telecommunication Fuse - 100 kAIC CE
Part Number: TPS-30LB
Quick Summary
TPS-30LB telecommunication fuse protects telecom PCB circuits by delivering fast, current-limiting fault interruption. Equipment downtime and surge events drive costly outages, so reliable fusing reduces risk and maintenance calls. It is CE marked to support regulatory compliance for European installations, aligning with common international protection standards. The fuse features a glass melamine tube, silver-plated ferrules, and a PCB tab plus bolt tag for dependable board mounting. Designed for compact telecom layouts, it avoids unnecessary field complexity while delivering robust protection for power rails and signal conditioning paths. For procurement teams, the 30 A rating with a 100 kAIC interrupt capability provides clear, actionable criteria for telecom protection on PCBs and line cards.

FAQs
TPS-30LB uses a PCB tab and bolt tag interface for secure mounting on standard telecom PCBs. Align the tab with the corresponding cutouts on the board, insert the fuse so the contacts are fully seated, and fasten the bolt tag to your terminal block or bus bar. Verify mechanical clearance and ensure there is no stress on the leads to maintain contact integrity. This design supports quick field replacement and minimizes assembly time in tight enclosures.
The TPS-30LB is rated for 30 A with a voltage rating of 170 Vdc and an interrupt rating of 100 kAIC. This combination provides strong overcurrent protection for telecom power rails while allowing fast interruption when a fault occurs. The current-limiting feature reduces energy transferred to downstream components, helping to preserve the life of sensitive devices in line cards and data interfaces.
Yes, the TPS-30LB carries CE marking, signaling compliance with essential health and safety requirements for European installations. While the listing highlights CE compliance, verify any site-specific regulatory or system-level standards in your project. The fuse’s 30 A, 170 Vdc, and 100 kAIC ratings align with typical telecom power and data pathways found in European equipment racks and line cards.
The TPS-30LB combines current-limiting behavior with a glass melamine tube and silver-plated ferrules, delivering reliable contact performance and fast fault isolation. This reduces the energy released during faults, mitigating damage to PCB traces and connectors in telecom networks. Its compact footprint and non-indicating design help maintain a clean assembly without compromising protection levels.
By delivering rapid fault isolation and robust overcurrent protection, the TPS-30LB reduces downtime and extends the life of downstream components, lowering maintenance frequency and replacement costs. Its compact form factor simplifies inventory management and field replacement in multi-slot telecom enclosures, contributing to lower lifecycle costs in both new builds and retrofit projects.
