FAQs
MV155F2DCX175E uses ferrule end x ferrule end connections and two barrels; it fits standard Bussmann MV fuse footprints in switchgear, motor-control centers, and distribution panels. The 0.75 in diameter and 23 in height define its physical envelope. Ensure the upstream protection scheme coordinates with a 50 kAIC interrupt rating and the 15.5 kV voltage rating.
This fuse provides a 175 A amperage rating, a 50 kAIC symmetrical interrupt rating, and a 15.5 kV voltage rating. It is a current-limiting, E-class device with a silver ribbon element inside a fiberglass tube. These ratings support precise protection coordination and fault-energy control in medium-voltage feeders and switchgear.
Ideal for medium-voltage feeders in switchgear, motor-control centers, and industrial power distribution networks. It helps protect feeders from high-energy faults while maintaining system uptime. The ANSI Class E rating supports standardized protection coordination, making it suitable for facilities that require reliable MV protection with documented performance.
MV155F2DCX175E carries ANSI certification and an ANSI-classified E rating, indicating compliance with recognized industry standards for medium-voltage fuses. The product notes indicate ‘Compliances: Contact factory’ for certain regulatory or regional requirements, so verify with Eaton for any additional approvals needed in your jurisdiction or application.
The fuse combines robust arc-quenching performance with a durable fiberglass body and silver ribbon element, reducing replacement frequency and maintenance downtime. The two-barrel ferrule-end design simplifies field swaps and stocking, improving maintenance efficiency. While upfront cost may be higher than basic fuses, higher uptime and improved protection coordination yield a favorable total cost of ownership over time.
