High interrupt rating and voltage capability deliver robust protection for telecom power systems. The TPS-35 supports 35 A and 170 Vdc with a 100 kAIC rating, enabling rapid fault interruption and reducing downstream damage. This is particularly valuable in telecom racks and data-center edge devices where fault events can cascade into expensive downtime.Current-limiting performance minimizes arc energy and conductor wear. By restricting fault current, it protects switchgear and cables from excessive thermal stress, which translates to longer component life and lower replacement costs. In practice, designers can specify a single device to cover multiple distribution blocks, simplifying BOMs and improving procurement efficiency.Non-indicating construction lowers panel complexity while maintaining reliable protection. Without visual indicators, panel layouts remain clean, and status monitoring focuses on proper function rather than indicator failures. For maintenance teams, this means simpler diagnostics and fewer nuisance trips in busy telecom environments.Ferrule-end x ferrule-end configuration and glass-melamine tube construction support easy installation and rugged service. The standard ferrule connections fit common fuse holders, reducing the need for adapters, while the glass-melamine tube provides dimensional stability and resistance to vibration in cabinet enclosures.RoHS compliance and CE marking align with global manufacturing and regulatory expectations. The TPS-35’s environmental and safety certifications help maintain supply-chain confidence and simplify audits, particularly for vendors serving international telecom networks. Together with Bussmann series compatibility, this fuse integrates seamlessly with existing protection schemes and field-installation best practices.

FAQs
TPS-35 uses ferrule-end connections designed for standard telecom fuse holders. Ensure the panel provides compatible ferrule sleeves and adequate clearance around the fuse block; the unit measures 0.56 in by 0.56 in by 0.87 in and weighs about 0.2 lb, which helps confirm fit in compact cabinets. Replace with an equivalent TPS-35 or Bussmann series fuse for consistent protection levels; observe 170 Vdc maximum voltage and 35 A rating to maintain electrical safety.
TPS-35 provides an interrupt rating of 100 kAIC and a voltage rating of 170 Vdc, with a 35 A current rating. This combination protects sensitive telecom equipment from high-energy faults while limiting voltage exposure to downstream circuits. Suitable for distribution blocks in telecom panels, it helps ensure quick isolation and protects power supplies and racks.
Yes. The TPS-35 is RoHS compliant and CE marked, reflecting compliance with European environmental and safety standards. This makes it suitable for global deployments, including regulated markets. Always verify the latest datasheet for any regional variants and ensure compatible packaging and documentation during procurement.
TPS-35 is explicitly designed for telecom power distribution and network infrastructure. Its ferrule-end design, non-indicating status, and current-limiting behavior make it ideal for telecom cabinets, edge devices, and data-center applications. Pair it with standard Bussmann series holders and ensure panel protection coordination with upstream fuses and circuit breakers.
TPS-35 offers low maintenance due to non-indicating status and rugged construction, with field-replaceable ferrule-end fuses minimizing service time. Its high interrupt rating reduces the risk of cascading faults, lowering downtime costs. Over time, consistent use supports longer equipment life and greater network availability in mission-critical telecom environments.
