That 55 kA figure tells you the breaker can safely interrupt a fault current up to that level without self-destruction — critical for selectivity studies in a distribution panel where the upstream transformer can deliver that kind of energy. The TM240 thermal-magnetic trip unit gives you an adjustable overload protection band from 560 A to 800 A (Ir), with a fixed short-circuit pickup at 5 times In (Ii = 5 x 800 A = 4000 A). That fixed magnetic threshold means the breaker is sized for a feeder or large motor branch where you want instantaneous trip above 4000 A, not a lower setting that could nuisance-trip on motor inrush. ## Deployment context This breaker mounts on a standard DIN rail or panel-mount base in a switchboard or motor control center enclosure. The integrated undervoltage release (UVR) at 120-127 V AC 50/60 Hz provides automatic trip on loss of control voltage — common in safety circuits where a downstream contactor or PLC must de-energize the load on power loss. The two HQ auxiliary switches (form C) are wired into the control circuit for status feedback to a PLC or SCADA input module.","metaTitle":"Siemens 3VA1580-5EF32-0CC0 Circuit Breaker, 800A, 55kA @ 415","metaDescription":"Siemens 3VA1580-5EF32-0CC0 IEC frame 1000 circuit breaker, 3-pole, 55kA breaking capacity at 415V AC.
