The TM120M thermal-magnetic trip unit provides motor-starting protection: the thermal element tracks overload heating in the motor circuit, while the magnetic instantaneous pickup is adjustable from 5 to 15 times In (625–1875 A), letting you set short-circuit protection above the motor's inrush without nuisance tripping. This version ships without overload protection (the TM120M is configured for short-circuit-only duty) and includes an undervoltage release (UVR) coil rated 208–230 V AC, 50/60 Hz — the UVR will trip the breaker if control voltage drops, which is standard for emergency-stop or undervoltage safety schemes in machinery. Clamp terminals accept copper or aluminum conductors without lug kits, which saves panel space and termination time. The 3VA1 frame is DIN-rail mountable, so it integrates into standard 35 mm DIN-rail enclosures alongside contactors and motor starters. The lifecycle stage for this order code is current. No last-time-buy or phase-out notice is on record.","metaTitle":"Siemens 3VA1112-5MH36-0DA0 Circuit Breaker, 125A, 55kA @ 415","metaDescription":"Siemens 3VA1112-5MH36-0DA0 IEC frame 160 MCCB, 3-pole, 125A, Icu=55kA @ 415V, TM120M trip, UVR 208-230V AC.
