The TM120M trip unit is thermal-magnetic: the thermal element handles overload protection (inverse-time curve), while the magnetic element provides short-circuit protection with an adjustable instantaneous pickup range of 5 to 15 times In (625 A to 1875 A). Note that this variant ships without overload protection — the TM120M provides only short-circuit protection, so an external overload relay is required for motor starting duty. The clamp-type terminals accept copper or aluminum conductors up to the frame's rated cross-section — no lug kit needed for most wiring. Rated for 50/60 Hz distribution systems. The 125 A continuous rating suits it for feeder protection in sub-distribution boards, backup generator outputs, or as a main disconnect for a machine cell drawing under 125 A full load.","metaTitle":"Siemens 3VA1112-6MH36-0AE0 Circuit Breaker, 125A, 70kA @ 415","metaDescription":"Siemens 3VA1112-6MH36-0AE0 IEC frame 160 circuit breaker, 3-pole, 125A, breaking capacity 70kA @ 415V.
