Eaton Specification Sheet - TPS-3
TPS-3 is rated for 170 Vdc and 3 A, delivering precise protection for telecom DC rails and data-center power feeds. The current rating aligns with common telecom supply topologies, preventing damage to sensitive equipment while maintaining uptime and service continuity in network infrastructure. With a 100 kAIC interrupt rating, the fuse withstands high fault currents typical of enterprise DC distributions, minimizing energy let-through and downstream damage in telecom cabinets. Its non-indicating design reduces maintenance overhead in remote sites, while ferrule-end terminations enable quick, reliable field installation and termination in cable harnesses for rugged telecom environments. The glass-melamine fuse body and silver-plated brass ferrules enhance durability in harsh enclosures, delivering long service life and predictable performance. Compliance with CE marking and RoHS reinforces regulatory readiness for EU deployments, while a standard packaging type simplifies stocking and procurement for electrical protection across campuses and data centers.

FAQs
TPS-3 is ideal for DC telecom protection in data centers, network cabinets, telecom racks, and outdoor or remote sites. Its 170 Vdc rating and 3 A current rating align with common telecom supply rails, while the 100 kAIC interrupt capability guards against severe faults without compromising normal operation. The ferrule-end connections support quick, reliable terminations in existing cable harnesses.
The 100 kAIC rating ensures the TPS-3 can safely interrupt large fault currents common in enterprise DC distributions, protecting downstream equipment from damaging energy. This translates to reduced risk of equipment damage, fewer unplanned outages, and a higher level of system reliability in data centers and telecom facilities where fault currents can be substantial.
Yes. The TPS-3 is CE marked and RoHS compliant, indicating regulatory readiness for European installations and safe material composition. While it is not listed with SIL or IP ratings in the provided data, the CE/RoHS status supports compliance in standard telecom environments and EU markets, aligning with typical procurement requirements for electrical protection components.
Absolutely. TPS-3 features ferrule-end x ferrule-end connections, designed for straightforward termination in ferrule-based cabling. This simplifies installation in telecom racks and DC power distributions, reduces field labor, and improves reliability by ensuring a robust mechanical and electrical connection in harsh environments.
TPS-3 is non-indicating, so steady-state status must be monitored via external protection schemes or supervisory controllers. Replacement intervals align with system-level maintenance practices and fault history, not the fuse itself. Its sturdy glass-melamine tube with silver-plated ferrules supports long life in telecom enclosures, contributing to lower maintenance frequency and predictable lifecycle costs.
