FAQs
Yes. MV155F2DBX150E uses ferrule-end x ferrule-end connections and a two-barrel design that aligns with Eaton Bussmann MV protection assemblies. Its standard form factor and current-rating align with common protection strategies in switchgear, motor control centers, and feeders, making it suitable for retrofit or new installations without custom hardware.
The fuse provides a 150 A amperage rating, a 15.5 kV voltage rating, and a 50 kAIC interrupt rating. It features current-limiting operation and a fiberglass tube with a silver ribbon element, two barrels, 0.75 in diameter, and a lengthy form factor suitable for medium-voltage protection schemes.
It is well suited for protection in switchgear, motor control centers, and feeders within manufacturing plants, chemical processing, and other heavy industrial environments. The combination of high interrupt rating and current-limiting characteristics helps protect downstream equipment, reduce arc energy, and improve system uptime in critical process lines.
The MV155F2DBX150E carries ANSI certification. Compliances may require factory confirmation for CE, SIL, or IP-specific requirements; users should contact Eaton for confirmation and any regional product variants or additional certifications needed for their installation and regulatory context.
By delivering fast fault clearing and current limitation, the fuse minimizes arc energy and protects upstream equipment, reducing maintenance interruptions and damage-related costs. Its durable fiberglass construction and standard ferrule-end connections streamline stocking and replacements, supporting predictable lifecycle costs and improved return on investment in MV protection schemes.
