It is configured for starter protection with a TM120M thermal-magnetic release, meaning the thermal element is sized for motor starting profiles while the magnetic short-circuit pickup is adjustable from 5 to 15 times In. The unit includes an undervoltage release (UVR) coil at 24 V DC and uses clamp (box lug) terminals. For motor starting duty, the TM120M thermal element provides inverse-time overload protection matched to a 125 A motor full-load current; the magnetic pickup range (5–15× In = 625–1875 A) covers locked-rotor and bolted-fault conditions. ## Where it is used This breaker is designed for motor branch circuits in industrial control panels — typically feeding a motor starter or contactor combination. The UVR coil connects to a 24 V DC safety circuit; verify polarity and that the coil draw does not exceed the control transformer rating.","metaTitle":"Siemens 3VA1112-6MH36-0BA0 Circuit Breaker, 125A, 70kA @ 415","metaDescription":"Siemens 3VA1112-6MH36-0BA0 IEC frame 160 circuit breaker, 3-pole, 125A, Icu=70kA @ 415V, TM120M starter protection, UVR 24V DC.
