The TM120M thermal-magnetic trip unit is set for 125 A and provides short-circuit protection adjustable from 5 to 15 times In, but note this variant ships without overload protection; it's configured for starter protection where the overload relay sits separately. The integrated shunt trip (STL) operates on 110–127 V DC or AC 50/60 Hz, letting you remotely trip the breaker from a safety circuit or E-stop chain. The clamp-type terminals accept copper or aluminum conductors up to the frame rating — no special lug kit needed for most panel builds. The shunt trip coil draws power from a separate control circuit; verify the control transformer or DC supply can source the inrush before wiring into the safety chain.","metaTitle":"Siemens 3VA1112-5MH36-0JA0 Circuit Breaker, 55kA @ 415V, 125","metaDescription":"Siemens 3VA1112-5MH36-0JA0 IEC frame 160 MCCB, 55kA breaking capacity at 415V, 125A TM120M trip, shunt trip 110-127V.
