Three-pole thermal-magnetic trip unit (TMA) covers overload and short-circuit protection at 690 VAC, 50/60 Hz. Sized for panelboard and sub-distribution duty where a compact, high interrupting-capacity breaker is needed. ## Delta — 3-pole vs 4-pole This 3-pole breaker shares the XT4 frame with the 4-pole 1SDA068104R1 (200 A, InN=50%). The physical fit differs: the 4-pole unit is wider at 14 cm vs 10.5 cm, and the wiring scheme expects a neutral pole. Dropping a 3-pole into a panel wired for 4-pole means reworking the neutral bus and losing a pole width. For 3-phase-only feeds, this is a direct fit; for mixed loads requiring switched neutral, specify the 4-pole variant.","metaTitle":"ABB 1SDA068088R1 XT4N 160 TMA 125-1250 3p F F, In 125 A","metaDescription":"ABB XT4N 160 distribution circuit breaker, 125 A TMA, 3-pole, 690 V, 50/60 Hz.
