Product details

The 1SDA068088R1: ABB XT4N 160 TMA 125-1250 3p F F distribution circuit breaker rated 125 A continuous (In) on a 160 A frame (Iu). 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.

Frequently asked questions

What are the rated current (In) and frame current (Iu) for this breaker?

Rated current In is 125 A; the maximum frame current Iu is 160 A. The breaker frame is sized for the TMA trip range, not the fixed setting.

Will this 3-pole breaker drop into a panel wired for the 4-pole 1SDA068104R1?

No—the 3-pole version is 10.5 cm wide; the 4-pole is 14 cm. The panel's mounting and busbar layout must match the pole count. Rewiring the neutral and adjusting the DIN rail position would be required.

What is the lead time for ordering this part?

Estimated lead time is 2 to 4 weeks. The part is sourced to order against an RFQ; no stock commitment is implied.
