The TM120M thermal-magnetic trip unit is set at 63 A (In) and provides starter protection for motor circuits: the thermal element tracks motor heating, the magnetic pickup is adjustable 5–15 x In for short-circuit protection, and there is no separate overload relay needed — the breaker itself does that job. Two auxiliary switches (HQ type) provide status feedback to the PLC or indication lamp. For BOM-line commitment, the key fit criteria are the 63 A TM120M trip, the 55 kA @ 415 V interrupting rating, and the UVR voltage (120-127 V AC). ## Deployment context The UVR coil draws continuously when energized; verify the control transformer is sized for the holding current.","metaTitle":"Siemens 3VA1163-5MH32-0CC0 Circuit Breaker, 55kA @ 415V, 63A","metaDescription":"Siemens 3VA1163-5MH32-0CC0 IEC frame 160, Icu=55kA @ 415V, 3-pole, TM120M, In=63A, starter protection, UVR 120-127V AC, 2 aux switches.
