Fuse Selection for VFDs (Electronic Motor Starters)

    Introduction

     

    Did you know that many manufacturers have cut costs by removing internal semiconductor fuses, leaving your VFD vulnerable to overvoltage and transient voltage conditions? But fear not, there’s a solution: High-Speed VFD Fuses!

    Here’s why they are a Game Changer

     

    • Protection at the Component Level: High speed fuses limit energy influx during short circuit faults, safeguarding internal VFD components like IGBTs from damage.
    • Minimize Downtime: By isolating damage and protecting components, these fuses make VFD replacement a breeze, reducing maintenance time and costs.
    • Safety First: Minimize arc flash hazards or personal injury – high-speed fuses lower the risk associated with short circuit conditions.
    • Approved and Certified: Mersen’s High Speed Class J (HSJ) fuses meet UL and CSA standards, ensuring top-notch quality and reliability.
    • Key Features and Benefits: Combining low I2t with branch-circuit performance, our HSJ fuses offer optimized overload capability and excellent cycling ability for frequent starts and stops.

    Keep your VFDs running smoothly with High-Speed Fuses. The maximum protection for your equipment.
