Protected: arc flash reduction and more

The Power Defense circuit breakers deliver arc flash reduction technologies that allow you to better protect your customers, your staff and your reputation. Built in technologies secure enhance safety.

  • Reduce arc flash energy levels
    Eaton's ArcFlash Reduction Maintenance System™ helps protect workers by reducing dangerous and potential arc flash incident energy levels. It enabling workers to activate this system from a safe distance without altering critical protection settings of the breaker.
  • Faster trip times
    Zone Selective Interlock (ZSI) technology protects equipment by intelligently selecting faster trip times in coordinated systems, an advantage which can keep operators safe and productive. Power Defense circuit breakers advance this proven technology by providing the ability to test the ZSI system functionality while visually indicating its operational status.
  • Preempt impending system failures
    Our Power Xpert® Release (PXR) electronic trip units are equipped with the latest microprocessor technology that notify you when your power distribution system needs to be maintained or replaced. PXR trip units also offer programmable relay alarms, which provide situational awareness to preempt impending system failures, keeping your facility on-line, safe, and productive.
