FAQs
The TP158HC is designed to be used with Type TPL‑B fuses and is intended for panel mounting. It features 1/4 inch - 20 TPI bolt line terminals, enabling straightforward installation on standard electrical panels. This compatibility reduces spare parts needs and simplifies wiring harness design, accelerating field deployments and serviceability while ensuring reliable DC protection in panel assemblies.
The TP158HC provides an 80 Vdc voltage rating, a current range of 70–250 A, and a short-circuit rating (SCCR) of 100 kA. It is fusible and designed for DC protection in industrial environments. These ratings support safe operation in mid‑ to high‑current DC circuits and help engineers meet protection standards for power distribution panels.
Yes, the TP158HC is designed for elevated-temperature operation, with a thermoplastic housing rated for up to 150 °C. This makes it appropriate for harsh industrial environments where enclosure temperatures can rise, reducing thermal constraints and enabling reliable performance without frequent component changes or cooling upgrades.
The TP158HC is RoHS compliant, supporting regulatory and sustainability requirements. For additional certifications, Eaton provides datasheets and catalogs (e.g., Bussmann series catalog no. 1007 and TP158HC datasheets); where needed, certifications can be confirmed by contacting the manufacturer or sourcing official datasheets for your compliance needs.
Using the TP158HC delivers faster, safer DC isolation with high fault‑current capability, minimizing downtime during faults and maintenance. Its panel‑mount design, compatible terminals, and RoHS compliance streamline installation, reduce field errors, and align with modern protection schemes, delivering lower total cost of ownership and improved system reliability in manufacturing and process environments.
