The Siemens 3VA1080-2ED32-0AC0 is a 3-pole IEC molded case circuit breaker from the 3VA1 frame 100 series, sized for 80 A continuous load with a fixed thermal-magnetic TM210 trip unit.
Overload protection is set fixed at Ir = 80 A, so the breaker is a straight swap for a 80 A feeder — no dial to mis-set. Short-circuit pickup is Ii = 10 x In (800 A), a fixed magnetic threshold that clears hard faults fast. The TM210 curve is thermal-magnetic, line-protection grade; for motor starting you would need a different trip characteristic, but for cable and distribution protection this is the standard choice.
