The breaker is configured for starter protection with a TM120M thermal-magnetic trip unit — the TM120M gives you an adjustable magnetic trip range of 5 to 15 times In (so 625 A to 1875 A at 125 A In), letting you dial in short-circuit protection to match the inrush of a motor starter without nuisance tripping. Note that this variant ships without overload protection (the TM120M covers short-circuit only here; overload coordination is handled externally by the starter overload relay).","metaTitle":"Siemens 3VA1112-6MH36-0DC0 Circuit Breaker, 125A, 70kA @ 415","metaDescription":"Siemens 3VA1112-6MH36-0DC0 IEC frame 160 circuit breaker, 125A, Icu=70kA @ 415V, 3-pole, starter protection TM120M, UVR 208-230V AC.
