FAQs
TPM-30 is designed to fit telecom and data-center power rails up to 80 Vdc, delivering a 30 A current rating with a 20 kAIC interrupt capacity. Its miniature, non-indicating form factor suits dense panels and standard protection schemes in data centers, telecom closets, and edge devices, enabling scalable protection without sacrificing cabinet space or serviceability.
By rapidly limiting fault current, TPM-30 minimizes the energy available to faults, reducing cascading failures and downtime. The 80 Vdc rating and 20 kAIC interrupt capacity guard critical circuits, while the small footprint eases panel layouts, enabling quicker replacement and fewer service interruptions during maintenance windows, ultimately lowering total cost of ownership.
Yes, TPM-30 is CE marked, signaling conformance with European safety directives for electrical protection devices used in telecom and data-center infrastructure. While CE compliance is highlighted, users should verify site-specific standards such as IEC and EN requirements. The marking supports multinational procurement and helps document compliance during audits.
TPM-30 features compact dimensions: 2.688 in length, 1 in height, and 0.375 in width, enabling dense panel layouts. It has standard packaging and a non-indicating indicator to simplify diagnostics. When wiring, align with 80 Vdc circuits and ensure adequate clearance for heat dissipation, following the datasheet for mounting and contact integrity.
The data set shows a Not Applicable warranty for TPM-30, indicating standard protection terms per Eaton policies. Maintenance benefits include a non-indicating design that reduces nuisance trips and simplifies fault tracing, saving inspection time. For lifecycle value, pair TPM-30 with compatible protection accessories and perform periodic functional tests per the specification sheet.
