Feature: Current-limiting performance minimizes let-through energy during a fault, protecting sensitive telecom electronics. Business Impact: Fewer surge damages translate to lower repair costs and shorter mean time to repair (MTTR). Application: Ideal for telecom power trees, line cards, and distribution panels in data centers and field installations. Feature: 170 Vdc rating with 20 A capacity aligns with common telecom DC rails and equipment protections. Business Impact: Ensures design margins, reducing the need for multiple part numbers across projects. Application: Used in DC power feeds to protect critical telecom assets. Feature: 100 kAIC interrupt rating provides robust fault current handling for central offices and high-energy systems. Business Impact: Improves system reliability and reduces risk of cascading failures. Application: Suitable for backbone telecom infrastructure and data-center protection schemes. Feature: Glass-melamine tube construction with silver-plated brass ferrules and ferrule-end connections delivers mechanical stability and reliable performance in vibration and thermal cycling. Business Impact: Longer service life and consistent performance under harsh conditions. Application: Field installations and rack-mounted panels where reliability matters. Feature: CE Marked and RoHS compliant with standard Bussmann series packaging. Business Impact: Simplifies regulatory compliance and procurement with a single, widely supported part. Application: Industrial electrical protection across European and global markets. Feature: Compact form factor—0.56 in length/width and 0.87 in height, weight 0.2 lb, ferrule-end connections for quick, secure assembly. Business Impact: Saves panel space and reduces installation time in dense enclosures. Application: Telecom enclosures, protection panels, and data-center distribution frames.

FAQs

The TPS-20 uses ferrule-end connections, enabling secure, quick mechanical terminations in standard fuse blocks. Ensure compatible ferrule tooling and a clean, debris-free cavity to maintain electrical integrity. The nocontact, non-indicating design simplifies visual checks and speeds routine maintenance.
TPS-20 is rated for 20 A at 170 Vdc with a 100 kAIC interrupt capability. This means it can safely interrupt high fault currents on DC telecom rails while supporting margin for typical data-center and field power systems, reducing the risk of equipment damage during faults.
Yes. With a 170 Vdc rating, 20 A capacity, and a high 100 kAIC interrupt rating, the TPS-20 protects critical telecom equipment and DC power paths in data centers and central offices, while its CE RoHS compliance aligns with European and global procurement standards.
The TPS-20 is CE Marked and RoHS Compliant, ensuring regulatory alignment for European markets and reduced hazardous substance concerns. These certifications support industrial deployments where compliance and sustainability are priorities.
