Eaton MV155F2DCS150E Fuse - E-rated 15.5 kV
Part Number: MV155F2DCS150E
Quick Summary
MV155F2DCS150E is an E-rated medium voltage fuse designed to protect MV switchgear and feeders. Engineers often contend with nuisance trips, arc flash risk, and downtime when selecting fuses, and mis-matches can escalate maintenance costs. This family supports clear risk management by providing defined current-limiting protection and robust performance in demanding environments. With a 15.5 kV rating and 150 A capacity, it delivers reliable protection while minimizing fault energy. While regional compliance requirements vary, factory confirmation can address CE or IEC pathways as part of a compliant installation. In practice, this model aligns with mission-critical protection strategies, offering a balance of protection, compatibility, and total cost of ownership that matters to procurement and engineering teams.

FAQs
Yes. The MV155F2DCS150E is designed for 15.5 kV systems and two-barrel construction, aligning with Bussmann series MV fuses and common frame dimensions. For exact frame compatibility and mounting tolerances, refer to the Eaton datasheet and confirm with the factory if your equipment uses non-standard frames.
Current-limiting action constrains fault current energy by interrupting the arc rapidly, reducing peak let-through current and downstream thermal stress. This minimizes insulation damage, extends component life, and lowers downtime during faults in medium-voltage feeders configured at 15.5 kV and up to 150 A.
Ideal for industrial facilities with medium-voltage switchgear, motors, and feeder networks. It is suitable for manufacturing plants, processing facilities, and utilities requiring reliable MV protection, with installation in Bussmann-series frames and standard MV distribution configurations.
Compliance details vary by region. The product requires factory confirmation for specific certifications such as CE or IEC standards. Always consult Eaton’s documentation and coordinate with the factory to ensure alignment with local electrical codes and regulatory requirements for your installation.
The fuse’s current-limiting behavior reduces fault energy and downtime, lowering repair costs and outage duration. Its non-indicating design can reduce maintenance checks, while standard packaging and catalog access streamline procurement and sparing. Overall, you gain predictable protection performance with lower long-term maintenance expenses.
