The Siemens 3VA1080-4ED32-0AA0-ZD00 is a 3-pole IEC frame 100 molded case circuit breaker rated 80 A continuous, with a fixed thermal-magnetic trip (TM210, FTFM) and a short-circuit breaking capacity of 36 kA at 415 V (class S). The Ir is fixed at 80 A and the instantaneous magnetic pickup Ii is set at 10 x In (800 A). It ships with a nut keeper kit for DC Power OEM applications in China.
What the ratings mean for fit
The 36 kA Icu at 415 V places this breaker in breaking capacity class S — it safely interrupts fault currents up to that level without welding or cascading upstream, which is the key coordination figure for a panel designer sizing the main or feeder breaker. The fixed Ir at 80 A means the overload protection is not field-adjustable; the breaker is ordered for that exact load current. The fixed Ii at 10 x In (800 A) gives a magnetic trip threshold suited for motor or transformer inrush without nuisance tripping on start-up. The 3VA1 frame is a compact IEC design that mounts on a DIN rail or panel-mount plate, so it drops into a standard distribution board or motor control center bucket.
