Dual Function Protection
AFCI Protection
The dual function breaker provides arc-fault circuit interrupter protection for compatible branch circuits where AFCI protection is required.
GFCI Protection
The same breaker also provides ground-fault circuit interrupter protection for compatible circuits where GFCI protection is required.
Plug-On Neutral Design
The plug-on neutral design allows the breaker to connect to the neutral system of compatible load centers without the traditional neutral pigtail used by standard dual function breakers.
This configuration requires electrical equipment specifically designed to accept plug-on neutral breakers. Confirm the exact load center and neutral connection arrangement before ordering.
