The TPS-40L delivers 40 A at 170 Vdc, with a 100 kAIC interrupt rating to provide precise protection for telecom DC rails and high fault currents. This translates into shorter outage windows and reduced risk to sensitive power electronics in data centers and network nodes. The PCB tab terminals enable straightforward mounting on standard PCBs, speeding installation and simplifying field service. Built around a glass-melamine tube with silver-plated brass ferrules, the fuse offers solid mechanical integrity in vibration-prone telecom racks and harsh environments. Current-limiting capability reduces arcing energy during faults, enhancing safety and extending equipment life. Being RoHS and CE compliant streamlines global procurement while maintaining regulatory alignment for controlled environments. Non-indicating behavior minimizes maintenance signals in quiet, high-uptime networks.

FAQs
Install TPS-40L on standard PCB footprints designed for 0.56 in wide fuses. Align the PCB tab terminals with the board pads, secure with solder or appropriate fasteners, and verify proper clearance for creepage and clearance per your enclosure. The PCB tab design supports straightforward hand or automated assembly, reducing installation time and improving repeatability in telecom cabinet builds.
100 kAIC means the fuse can interrupt fault currents up to 100,000 amperes at the rated conditions, protecting power distribution paths from extreme surge events. For telecom networks, this specification helps safeguard critical equipment, minimizes arc energy during faults, and supports compliance with high-availability requirements without compromising equipment longevity.
Yes. With a 170 Vdc rating, 40 A current capacity, and a robust 100 kAIC interrupt rating, TPS-40L is designed for DC telecom rails in data centers and network equipment. Its PCB tab, current-limiting performance, and RoHS/CE compliance make it a reliable, regulator-friendly choice for protecting DC power paths in modern facilities.
TPS-40L carries CE marking and RoHS compliance, indicating adherence to essential health, safety, and environmental standards across many regions. These certifications simplify procurement for global projects, help meet supplier requirements, and support regulatory alignment in equipment cabinets, data centers, and telecom infrastructure where reliable compliance is essential.
The TPS-40L provides a predictable, long service life with a non-indicating design that reduces nuisance maintenance signals in high-availability environments. Its current-limiting action lowers arc energy, protecting costly electronics and reducing downtime. Combined with RoHS/CE compliance, this fuse helps lower total cost of ownership by simplifying sourcing and extending uptime in mission-critical telecom and data-center applications.
