This variant ships with a TM120M thermal-magnetic trip unit configured for starter protection (AM characteristic). The thermal element is omitted — no overload protection — so it's a short-circuit-only device intended to sit upstream of a separate motor overload relay. ## Panel integration and accessories The breaker includes a nut keeper kit for secure mounting in the panel. The auxiliary switch signals the breaker's open/closed position; the trip alarm switch changes state only when the breaker trips on fault, giving a dedicated remote indication for the SCADA or PLC input.","metaTitle":"Siemens 3VA1112-6MH32-0AG0 Circuit Breaker, 125A, 70kA @ 415","metaDescription":"Siemens 3VA1112-6MH32-0AG0 IEC frame 160 circuit breaker, 3-pole, 125A, 70kA breaking capacity at 415V.
