What this breaker is
The 1SDA068082R1: The ABB SACE XT4N 160 TMD 32-320 3p F F is a three-pole distribution circuit breaker from the XT4 frame. Rated 32 A continuous (In) with a 160 A frame (Iu), it uses a fixed thermal-magnetic trip unit for overload and short-circuit protection at 690 V, 50/60 Hz. The 'F' termination indicates fixed front terminals for panel wiring.
What the key ratings mean for fit
The 32 A In and 160 A Iu define the rating and frame. The fixed TMD trip at 690 V protects over currents with no field adjustment.
