- For providing overload, short circuit protection and detecting 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
- Have 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-forms associated with switched mode power supplies on electrical appliances, computers and lamp dimmers
- Visi-Trip™ trip indicator
