Its continuous rated current (In) is 40 A, mounted on a 160 A frame (Iu). The breaker handles 690 V at 50/60 Hz and uses a thermal-magnetic (TMA) trip unit, adjustable across the 40–400 A range per the type designation. ## Trip unit and adjustment TMA stands for thermal-magnetic adjustable. The In setting is fixed at 40 A from the factory, but the trip unit accepts adjustment of the thermal overload and magnetic short-circuit thresholds across the 40–400 A range. That makes it field-flexible for circuit re-rating without swapping the breaker.","metaTitle":"ABB 1SDA068083R1 XT4N 160 TMA, 40 A","metaDescription":"Active-production ABB 1SDA068083R1 XT4N 160 TMA distribution circuit breaker. 40 A continuous, 160 A frame, 3-pole, 690 V.
