3-phase serial RS-232 controlled panel board has as many RS-232 controlled circuits as you need in one power panel. You can mix RS-232 controlled motorized branch breakers and standard QO breakers together for a single power panel solution. The panelboard is big and roomy with lots of space to work (250% more room than a load center), which makes it the electricians' favourite. Big as it is, the SCP still saves valuable wall space when compared to traditional relay-based control systems. 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.
