It ships without overload protection — the TM120M provides short-circuit protection only, with adjustable instantaneous pickup Ii=5…15 × In. The TM120M magnetic-only release (no thermal overload element) means this breaker is intended for motor starter protection where overload protection is handled by a separate overload relay; the adjustable instantaneous trip (5–15 × In) lets you coordinate with the motor inrush without nuisance tripping.","metaTitle":"Siemens 3VA1112-5MH32-0CH0 Circuit Breaker, 125A, 55kA @ 415","metaDescription":"Siemens 3VA1112-5MH32-0CH0 IEC frame 160 MCCB, 125A, Icu=55kA @ 415V, starter protection TM120M, UVR 120-127V AC.
