This variant is configured for starter protection: the TM120M thermal-magnetic trip unit is set for motor starting inrush, with an adjustable magnetic short-circuit pickup Ii = 5...15 x In (625 A to 1875 A). Note it ships without overload protection — the description explicitly states 'without overload protection' — so the motor's thermal overload relay must be provided separately in the starter circuit. The integrated undervoltage release (UVR) operates on 120-127 V AC, 50/60 Hz. If the control voltage drops, the UVR trips the breaker open — standard for emergency-stop or undervoltage protection schemes. ## Deployment context The 125 A rating and 70 kA breaking capacity suit it for motor branch circuits, feeder protection, or as a main disconnect in smaller distribution boards where high fault current is expected.","metaTitle":"Siemens 3VA1112-6MH32-0CH0 Circuit Breaker, 125A, 70kA @ 415","metaDescription":"Siemens 3VA1112-6MH32-0CH0 IEC 3VA1 frame 160 breaker, 125A, 70kA breaking at 415V, with undervoltage release and aux switches.
