It carries starter protection TM120M, AM — a thermal-magnetic trip unit with a fixed thermal element (no overload adjustment) and an adjustable magnetic short-circuit pickup Ii=6...14 x In. This is sized for motor starter protection: the thermal element tracks motor heating, while the magnetic pickup is set above the motor's inrush to avoid nuisance trips on start. The auxiliary switch signals the breaker's ON/OFF status; the trip alarm switch signals only when the breaker has tripped on fault — useful for remote annunciation on a motor control center (MCC) or PLC input. Starter protection TM120M means no separate overload relay is needed for the motor branch. The adjustable magnetic pickup (Ii=6...14 x In) lets you set the short-circuit threshold to ride through motor starting current without tripping. ## Panel Integration The nut keeper kit holds the terminal nuts captive during wiring — saves time on assembly when you're landing 200 A cable lugs in a tight enclosure.","metaTitle":"Siemens 3VA1220-5MH32-0AG0 Circuit Breaker, IEC 250A Frame,","metaDescription":"Siemens 3VA1220-5MH32-0AG0 circuit breaker, IEC frame 250, 55kA @ 415V, 3-pole, In=200A, starter protection TM120M.
