FAQs
TPS-50V uses a vertical PCB tab design designed for straightforward solder-in mounting on standard PCBs. The fuse is non-indicating with a glass melamine tube and silver-plated ferrules, offering robust mechanical integrity. Its footprint aligns with Bussmann series devices, simplifying board layout and reducing commissioning time in telecom and data-center applications.
TPS-50V is intended for DC telecom power rails, DC distribution frames, telecom switches, and data-center equipment. Its 170 Vdc rating supports common DC distributions, while the 50 A rating and 100 kAIC interrupt rating protect sensitive power supplies and downstream electronics from high-energy faults, improving reliability and uptime in mission-critical environments.
Key ratings are 50 A amperage, 170 Vdc voltage, and a 100 kAIC interrupt rating, with current-limiting action. These specifications enable fast fault isolation, protect downstream gear, and minimize fault energy delivered to power supplies and transformers. This supports a protection strategy that prioritizes uptime, component longevity, and safe operation in high-energy telecom networks.
Yes. TPS-50V carries CE marking and RoHS compliance, aligning with European safety and environmental requirements. These certifications support global deployments and regulatory audits, providing assurance that the fuse meets essential compliance criteria while enabling smoother procurement across international sites.
With a durable glass melamine tube and robust ferrules, TPS-50V offers long service life and low maintenance needs. The high 100 kAIC interrupt rating reduces outage risk and downstream repair costs, delivering a favorable return on investment in large telecom deployments as uptime improves and replacement intervals are extended.
