It ships with a TM120M thermal-magnetic trip unit set for starter protection — magnetic pickup adjustable 5–15× In (625–1875 A), no overload function (the motor starter handles that). The shunt trip (STL) coil accepts 110–127 V DC or AC 50/60 Hz, so a remote emergency-stop or fire-alarm contact can drop the breaker without walking to the panel. Two auxiliary switches (HQ) report position back to the PLC or status lamp. The nut keeper kit (included) holds the terminal screws captive during wiring — saves dropping hardware into a live panel. The shunt trip occupies the left-side accessory slot; the two auxiliary switches fit the right-side slot. No extra wiring space needed beyond the standard 3VA1 footprint.","metaTitle":"Siemens 3VA1112-5MH32-0JC0 Circuit Breaker, 125A, 55kA @ 415","metaDescription":"Siemens 3VA1112-5MH32-0JC0 circuit breaker, IEC 3VA1 frame 160, 3-pole, 125A, Icu=55kA @ 415V.
