Can mix RS-232 controlled motorized branch breakers and standard QO breakers together for a single power panel solution. The SCP comes with 200% neutrals to reduce neutral overheating caused by switch-mode power supplies. The SCP series also offers bolt-on breakers as an option to traditional plug-on models, and can control one, two or three pole breakers.
