Eaton MV155F1DCX100E E-rated fuse - ANSI certification
Part Number: MV155F1DCX100E
Quick Summary
MV155F1DCX100E is an E-rated fuse engineered to protect medium-voltage power systems up to 15.5 kV. In real-world installations, selecting an undersized or inappropriate fuse drives nuisance trips, equipment damage, and unplanned downtime. This Eaton Bussmann series device carries ANSI certification and Class E construction, with a rugged fiberglass tube and current-limiting design to withstand demanding environments. For reliability and operational efficiency, its non-indicating indicators and ferrule-end connections simplify stocking, replacement, and preventive maintenance, while providing predictable protection margins that support longer asset life and safer, compliant power distribution. The fuse aligns with standard MV protection schemes and leverages Eaton's specification sheets for fast engineering validation.

FAQs
MV155F1DCX100E uses ferrule end x ferrule end connections and a single 1-barrel design, enabling straightforward mounting into common switchgear and bus assemblies. Its compact 0.75 in diameter with a tall housing supports convenient replacement in crowded enclosures, while the ferrule ends ensure reliable, vibration-resistant contact during fault events.
The fuse is rated at 15.5 kV, 100 A, with a 50 kAIC interrupt rating. This means it can safely interrupt up to 50 kiloamps of fault current at 15.5 kilovolts, protecting downstream equipment by quickly isolating faults and limiting energy transfer to sensitive components.
Yes. With current-limiting action, a high interrupt rating, and a robust Class E construction, the MV155F1DCX100E is appropriate for protecting transformers and feeders in medium-voltage distribution, helping to minimize arc energy, reduce collateral damage, and support reliable system operation.
The MV155F1DCX100E carries ANSI certification and is manufactured to Class E specifications. While Compliances list requires factory contact, these certifications provide formal reliability and performance metrics that support procurement audits and regulatory alignment in industrial settings.
You can access the Eaton specification sheet MV155F1DCX100E and the Bussmann series catalogs listed in the product downloads. These documents provide comprehensive ratings, installation guidelines, and compatibility information to accelerate engineering validation and procurement.
