The thermal-magnetic trip unit (TM220) gives you adjustable overload protection (Ir = 44 A to 63 A) and a fixed short-circuit pickup at 10 x In, so it's set for motor or feeder protection where you need a deliberate magnetic threshold to avoid nuisance trips on inrush. ## Built-in undervoltage release and keeper kit The UVR drops the breaker on loss or dip of control voltage — standard for safety circuits where a downstream machine must trip if the control supply fails. The keeper kit retains the mounting nuts during panel assembly, which saves time on a DIN-rail or backplate install.","metaTitle":"Siemens 3VA1163-5EE32-0CA0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5EE32-0CA0 IEC frame 160 MCCB, 55kA breaking capacity at 415V, 63A thermal-magnetic, UVR 120-127V AC.
