  • Applications
  • Features
For providing overload and short circuit protection designed to detect arc faults
An arc fault circuit breaker opens the circuit and stops the arcing and high intensity heat before a fire is likely to ignite
Special microprocessor based arc identification to differentiate necessary operational arcs (associated with loads such as electric motors, switches and receptacles) from actual arc faults which can cause damage and fires
Differentiate true arc faults from chopped wave-form associated with switched mode power supplies on electrical appliances, computers and lamp dimmers
14 to 8 AWG copper, 12 to 8 AWG aluminum wire
