The frame rating (Iu) of 250 A tells you the maximum thermal-magnetic trip unit that fits this XT4N chassis; the installed TMA unit is set at the factory for the 200–2000 A range, but the frame itself is physically rated for 250 A. At 690 V rated voltage and 50/60 Hz, this MCCB covers both 400 V and 690 V distribution systems without derating the continuous current — the voltage rating is the insulation ceiling, not a load limit. ## TMA trip unit — what it protects and how it responds The TMA designation means thermal-magnetic adjustable: the thermal element (for overload protection) is field-adjustable via a dial on the front face, while the magnetic element (for short-circuit protection) has a fixed threshold. This gives the panel builder or site engineer the ability to tune the overload pickup to the actual load current without swapping the trip unit. The 200–2000 A range in the type code refers to the trip unit's adjustment span, not the continuous rating — the In of 200 A is the nominal setting the breaker ships with. If the connected load draws 180 A continuous, the thermal dial can be turned down to match; if it draws 220 A, the breaker must be replaced with a higher In unit or the frame swapped. ## Panel fit and mounting dimensions At 8.25 cm wide by 10.5 cm deep by 16 cm tall, this 3-pole MCCB fits the standard XT4 cutout and mounting pattern — the same footprint as other XT4N 250 A frame breakers, so a panel layout designed for one XT4 variant accepts this unit without re-drilling. The 3-pole configuration with front-face terminals (F F in the type code indicates front-front connection) means line and load cables both terminate on the front face — no rear-connection hardware needed. This simplifies busbar routing in a distribution panel where the breaker is fed from a vertical bus and feeds downstream loads on the same plane.","metaTitle":"ABB 1SDA068090R1 XT4N 250 TMA 200-2000 3p F F MCCB, 200 A","metaDescription":"ABB 1SDA068090R1 XT4N 250 MCCB, 200 A continuous (In), 250 A frame (Iu), 3-pole, TMA trip unit, 690 V, 50/60 Hz.
