FAQs
The TPS-B-30 is designed for standard fuse holders used in Bussmann series protection devices. Ensure the panel provides a compatible DC rail rated for 170 Vdc, with a 30 A fuse rating. With its glass-melamine tube and silver-plated ferrules, insert the fuse into the holder until fully seated, then verify continuity and system voltage. Always observe manufacturer guidelines and de-energize the panel before service.
Key specs include a 30 A amperage rating, 170 Vdc voltage rating, and a 100 kAIC interrupt rating. It is current-limiting to reduce fault energy, and it is non-indicating. The device uses a glass-melamine tube with silver-plated brass ferrules, and it is RoHS compliant and CE marked for regulatory alignment.
Yes. The TPS-B-30 is RoHS compliant and CE marked, making it appropriate for global telecom deployments and OEMs that must meet environmental and safety standards. This certification aids in achieving regulatory approvals and streamlining supplier qualification for integrated protection solutions.
Industries include telecom, data centers, and industrial networks employing DC power rails. Applications span telecom cabinets, DC distribution panels, and edge equipment protection where fast fault interruption minimizes downtime and protects critical infrastructure from high-current faults.
The current-limiting 100 kAIC fuse reduces fault energy, lowering the risk of downstream damage and downtime. Non-indicating design minimizes nuisance maintenance in monitored systems, while compact packaging eases replacement and inventory handling, resulting in lower maintenance labor costs and improved equipment availability.
