Eaton Specification Sheet - TPN-30
Feature 170 Vdc rating and 30 A amperage rating provides robust protection for DC telecom power rails. Business Impact: Prevents equipment damage from overcurrent events and reduces downtime in critical networks. Application: DC power distribution units and telecom enclosures benefit from reliable, fast fault clearance. Long-tail keywords: DC circuit protection, telecom power rail protection. Feature Current-limiting and high interrupt rating (100 kAIC) minimizes fault energy and arc opportunities. Business Impact: Lowered thermal stress and wiring damage, extending component life and lowering maintenance costs. Application: Rack-mounted telecom systems and data-network gear. Feature Ferrule-end x ferrule-end connections with silver-plated terminals improve contact reliability and ease of installation. Business Impact: Faster, more secure wiring harnessing and fewer field failures. Application: Assembly with standard ferrule crimp tooling in cabinet backplanes. Feature Compact dimensions and weight (0.56 in L, 0.56 in W, 2 in H; 0.5 lb) support dense layouts. Business Impact: Saves panel space and simplifies stocking, enabling higher port density. Application: Small-form telecom enclosures and high-density cabinets. Feature Non-indicating fuse reduces visual clutter in panel dashboards. Business Impact: Quicker visual inspection with fewer distractions; easier replacement in high-duty environments. Application: Any installation with limited panel clearance and visible indicators are not required.

FAQs
The TPN-30 is designed for telecommunication and data-network DC environments. It protects power rails in telecom enclosures, network routers, switches, and DC distribution cabinets. With a 170 Vdc rating and 100 kAIC interrupt capacity, it suits high-energy DC fault scenarios. Ensure ferrule-end terminations are compatible with your wiring harness and crimp tooling.
The TPN-30 carries a 30 A amperage rating, 170 Vdc voltage rating, and 100 kAIC interrupt rating. In practice, this means it can safely interrupt high-energy DC faults and limit fault current to protect conductors and devices. Operate it within these specifications to maximize protection in telecom DC distributions and related gear.
The ferrule-end x ferrule-end design with silver-plated terminals provides reliable crimp connections and low-contact resistance. This simplifies wiring, reduces connection failures in dense panels, and supports quick field replacements with standard crimp tools. It’s especially advantageous in high-density telecom cabinets where secure, repeatable terminations matter.
The data for this model lists Compliances as Not Applicable. Before deployment, verify CE, UL, or other regional regulatory standards required for your project. Always cross-check with your procurement and compliance teams to ensure the part meets local safety and performance requirements in telecom environments.
Expect improved uptime due to robust overcurrent protection and a current-limiting design that minimizes fault energy. The non-indicating fuse reduces panel clutter, while ferrule-term connections speed installation and field service. Over time, these factors translate to fewer fuse replacements, lower maintenance costs, and faster fault diagnosis in dense telecom estates.
