The ABB 1SDA068113R1 is a 3-pole motor protection circuit breaker from the XT4N 160 MA series, sized for motor branch circuits. It carries a rated current In of 12.5 A and a frame current Iu of 160 A, with an MA trip unit — magnetic-only, no thermal element, so it relies on an external overload relay for thermal protection. Rated voltage is 690 V at 50/60 Hz.
The MA trip unit is adjustable (Im=62.5...125 A on the type label), so you set the magnetic trip threshold to match the motor's starting inrush — typically 8–12× FLA for a standard induction motor. No thermal overload means you pair this with a separate overload relay (e.g., ABB Tmax or electronic relay) for the motor's thermal protection.
