FAQs
TPS-70LB offers PCB tab and bolt-tag mounting options, allowing flexible integration into diverse panel designs. This compatibility streamlines retrofits and new builds in telecom power distribution units, data centers, and rack-mounted systems, reducing install time and minimizing the need for additional hardware. Ensure mounting holes align with your panel’s tab connectors for optimal contact and reliability.
TPS-70LB is rated at 70 A with a voltage rating of 170 Vdc and an interrupt rating of 100 kAIC. It is a current-limiting, non-indicating fuse with a glass melamine tube and silver-plated brass ferrules, designed for PCB tab and bolt-tag mounting. Typical dimensions are 0.51 in length, 1.5 in height, and 0.3 in width, with a weight of about 0.2 lb.
Yes. The TPS-70LB combines high interrupt capability with compact form factor, making it ideal for DC telecom power rails in data centers and rack-mount distributions. Its non-indicating profile reduces panel clutter, while its robust ratings help protect essential equipment from overcurrent events, supporting uptime and service level objectives.
TPS-70LB is CE-marked and RoHS compliant, meeting European regulatory requirements and restricting hazardous substances. These certifications facilitate cross-border procurement, supply chain compliance, and sustainability goals, which are critical for multinational deployments and OEM integration in telecom and data center environments.
Because TPS-70LB is non-indicating, maintenance plans rely on periodic inspection and external signaling as needed. Its high 100 kAIC interrupt rating and current-limiting behavior reduce arc energy and equipment wear, lowering downtime and replacement costs over the fuse's operational life. This translates to improved system reliability and lower total cost of ownership in complex telecom deployments.
