This is the internal switching mechanism — not a complete MCCB with terminals and arc chamber housing — intended as a service replacement or for panel builders assembling custom breaker configurations. Rated Iu 160 A continuous current, this breaking part fits into the XT2 frame size, ABB's compact MCCB platform for distribution and motor branch circuits up to 160 A. The 690 V rated voltage (Ur) gives headroom on 400/480 V systems, and the 50/60 Hz rating covers global mains frequencies. ## Interrupting capacity and fault clearing For a 160 A frame, 70 kA Icu is a high-capacity rating, suitable for installations with high available fault current near the transformer or main switchboard, where lower-rated breakers would need upstream current-limiting fuses. In a typical 400 V industrial distribution panel, this breaking part coordinates with upstream and downstream devices to achieve selective coordination — the 70 kA Icu ensures it clears a fault at its terminals without forcing the main breaker to trip, keeping other circuits live. Sourced to order against the BOM quantity through independent distribution.","metaTitle":"ABB 1SDA068166R1 XT2 Breaking Part, 160 A, 70 kA Icu, 3-Pole","metaDescription":"ABB 1SDA068166R1 XT2L 160 breaking part, 3-pole, rated 160 A Iu, 70 kA Icu at 415 V, 690 V.
