The "AB" suffix designates the trip curve / accessory configuration for this Square D FA-frame breaker — in this case indicating a standard thermal-magnetic trip unit rated for Phase I line applications at 277 V. If you need a specific trip characteristic (e.g., electronic trip or a different accessory option), let us know and we can help identify the correct variant.
Yes. The FA24025AB is rated up to 277 V AC, so it is compatible with 240 V and 208 V systems as well. Just ensure the panelboard bus is rated for the FA plug-in frame and that the 18 kA interrupting rating meets or exceeds the available fault current at the installation point.
