The Siemens 3VA1080-2ED32-0JA0 is a 3-pole IEC molded-case circuit breaker from the 3VA1 series, frame size 100, with a fixed 80 A thermal-magnetic overload (TM210, Ir = 80 A) and a fixed short-circuit pickup of 10 x In (Ii = 800 A). The built-in shunt trip (STL) operates on 110–127 V DC or AC, 50/60 Hz, allowing remote or emergency-off tripping without an external undervoltage module.
Deployment context
The fixed Ir = 80 A and fixed Ii = 10 x In mean this breaker is a drop-in replacement for a specific BOM line — no field-adjustable dials, so verify the load's full-load amps match 80 A before specifying.
