It is a 3-pole unit with a TM120M trip unit set at In=125 A, designed for starter protection — meaning it provides short-circuit protection (adjustable Ii=5...15 x In) without overload protection, relying on an external overload relay for motor branch circuits. ## Key Ratings and Fit The TM120M thermal-magnetic trip unit is fixed at 125 A, with the magnetic short-circuit pickup adjustable between 5 and 15 times the rated current (625 A to 1875 A), letting you coordinate with downstream motor starting inrush. The 3VA1 frame is a standard panel-mount design with clamp terminals for easy wiring.","metaTitle":"Siemens 3VA1112-6MH36-0AH0 Circuit Breaker, 70kA @ 415V, 125","metaDescription":"Siemens 3VA1112-6MH36-0AH0 IEC frame 160 circuit breaker, breaking capacity class H Icu=70kA @ 415V, 3-pole, 125A, TM120M.
