The 1200 A frame rating sets the continuous current limit; downstream coordination starts from that number. This breaker carries UL listing (the "FF UL" suffix), so it is accepted in North American panel shops and for UL 508A industrial control panels.
Where you'll find this breaker
This is a panel-mounted MCCB, sized for a 1200 A main or large feeder in a switchboard or motor control center. The EKIP TOUCH trip unit gives you local programming and metering via the touchscreen interface — handy for setting long-time pickup and delay bands without swapping rating plugs. It fits the standard XT7H drawout or fixed-mount chassis, so if you're retrofitting an existing XT7H bucket, the cradle stays.
