The ABB 1SDA068110R1 is a 4-pole XT4N 250 distribution breaker with a TMA (thermal-magnetic) trip unit, rated 225 A continuous at 690 V. The frame uninterrupted current (Iu) is 250 A, meaning the breaker can carry up to 250 A provided the thermal setting is adjusted; at 225 A it runs well within the frame's capability. The TMA trip provides fixed overload and short-circuit protection, adjustable via external dials. This variant is configured for 50/60 Hz and handles three-phase plus neutral switching.
