Eaton MV155F2DCX200E Fuse - 15.5 kV, 50 kAIC ANSI
Part Number: MV155F2DCX200E
Quick Summary
MV155F2DCX200E is a high‑reliability MV fuse designed for medium‑voltage protection in industrial power systems. Engineers often contend with nuisance tripping and extended downtime when safeguarding feeders; this fuse combines current limiting with a robust ferrule‑end connection to minimize fault arc exposure and restore service quickly. The device carries ANSI certification, and Eaton provides additional compliance details through factory guidance to fit specific regional requirements. Built on the Bussmann series lineage, it suits utility‑grade and manufacturing installations alike. The compact 0.75 inch by 0.75 inch footprint and 23 inch height support simple cabinet or bus‑mounted integration, while the 2‑barrel construction supports scalable protection for multi‑feed arrangements. This enables safer, more cost‑effective protection and easier maintenance.

Eaton Specification Sheet - MV155F2DCX200E
MV155F2DCX200E combines a 15.5 kV voltage rating with a 200 A amperage rating and a 50 kAIC interrupt level. The current‑limiting behavior reduces fault energy and arc duration, translating to shorter outages and safer maintenance windows. This is ideal for feeders feeding motors, transformers, and critical loads in manufacturing facilities and power utilities. The ferrule‑end, ferrule‑to‑ferrule connection and fiberglass tube deliver mechanical robustness and corrosion resistance, supporting reliable operation in both switchgear and field installations. The non‑indicating design lowers maintenance requirements while preserving clear fault protection, and ANSI certification reinforces regulatory compliance across regions. Its two‑barrel configuration enables scalable protection for multi‑feed arrangements, while its compact footprint simplifies cabinet integration and serviceability. Overall, MV155F2DCX200E provides durable protection, faster fault clearance, and lower total cost of ownership in demanding environments.

FAQs
MV155F2DCX200E uses ferrule end connections and a compact 0.75 in by 0.75 in profile with a 23 in height. Choose a mounting location that provides stable support for the two barrels and allows easy access to the ferrule ends for wiring termination. Ensure enclosure clearances meet utility and NFPA guidelines, and align the unit with compatible Bussmann series components for a seamless protection scheme.
Key ratings are 15.5 kV voltage, 200 A amperage, and a 50 kAIC interrupt rating. The current‑limiting feature minimizes fault energy, reducing arc exposure and downtime. It is designed for medium‑voltage feeders in industrial and utility environments, with a non‑indicating indicator and ferrule ends for reliable field installation.
Yes. MV155F2DCX200E is part of Eaton’s Bussmann medium‑voltage fuse family and is designed for compatibility with standard Bussmann series mounting and enclosure practices. Verify cabinet space and conductor terminations, and reference the Eaton specification sheet for recommended accessories and interconnections to ensure seamless integration.
The MV155F2DCX200E lists ANSI certification, with additional compliance details available from Eaton via factory guidance. For project‑specific approvals (regional standards, SIL/CE requirements, or IP ratings), contact Eaton to obtain the appropriate certificates and documentation.
The current‑limiting design reduces fault energy and short‑circuit duration, lowering downtime and arc exposure. Its robust construction and non‑indicating design reduce maintenance overhead, while ANSI certification helps streamline procurement and regulatory approvals. Over the life of a protected feeder, this translates to lower maintenance costs and improved system availability.
