The TM120M thermal-magnetic trip unit is set for starter protection: the thermal element tracks motor heating, and the magnetic pickup is adjustable 5–15 x In, so you set it just above the motor's locked-rotor inrush without nuisance tripping on start. This breaker ships with a shunt trip (STL) coil rated 12–30 V DC or 24 V AC 50/60 Hz — a remote-trip input for emergency-stop or PLC-driven shutdown. No overload relay is built in; this is a magnetic-only short-circuit protector paired with an external overload (the 'AM' designation), so the motor's thermal protection is handled separately, typically by a Siemens 3RU2 or similar block.","metaTitle":"Siemens 3VA1112-5MH32-0HA0 Circuit Breaker, 125A, 55kA @ 415","metaDescription":"Siemens 3VA1112-5MH32-0HA0 circuit breaker, IEC frame 160, 3-pole, 125A, Icu=55kA @ 415V.
