FAQs About Fenarro's Vacuum Load Break Switches

  • Q Do you provide fused load break switches?

    A Yes, we offer combined load break switch-fuse units for transformer protection applications.

  • Q What maintenance is required for vacuum load break switches?

    A Minimal maintenance - visual inspection every 5 years and mechanical operation check annually.

  • Q Can your load break switches be automated?

    A Yes, we offer motorized versions with remote control capability and SCADA integration options.

  • Q What is the difference between load break switches and circuit breakers?

    A Load break switches can interrupt load currents but not fault currents, while circuit breakers can interrupt both load and fault currents.
