The TM120M thermal-magnetic release provides starter protection (motor branch circuit), but note the description flags 'without overload protection' — the TM120M here is configured for short-circuit protection only, with an adjustable instantaneous trip Ii = 5–15 × In. The integrated shunt trip (STL) operates on 220–250 V DC or 208–277 V AC, letting you remotely trip the breaker from a safety circuit or E-stop chain. Mounts on DIN rail in a standard IEC enclosure. The shunt trip occupies the accessory slot; verify coil voltage matches your control circuit before commissioning (220–250 V DC or 208–277 V AC). The 3VA1 frame 160 is physically compact for its 125 A rating, leaving fill-factor room in the gland plate for additional branch feeders.","metaTitle":"Siemens 3VA1112-6MH32-0KA0 Circuit Breaker, 125A, 70kA @ 415","metaDescription":"Siemens 3VA1112-6MH32-0KA0 IEC frame 160 circuit breaker, 125A, 70kA breaking capacity @ 415V AC.

That's suitable for high-fault-capacity industrial panels where the available short-circuit current is substantial."},{"question":"Does this breaker include overload protection?","answer":"No — the TM120M release on this variant is configured for short-circuit protection only (adjustable Ii = 5–15 × In). Overload protection is not provided, so you must size upstream or downstream overload relays separately for motor branch circuits."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1112-6MH32-0KA0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA1112-6MH32-0KA0 when reusing this data.
