The thermal-magnetic trip unit is a TM120M set at 63 A (In), configured for starter protection. The description states 'without overload protection' — this unit provides short-circuit protection only (Ii adjustable 5–15 x In). Integrated accessories include a shunt trip (STL) rated for 110–127 V DC or AC 50/60 Hz, plus two HQ auxiliary switches for remote status indication. A nut keeper kit is also included for secure mounting in the panel. For BOM freeze or PCN watch purposes, this part is a safe line-item commitment. If you are managing a multi-year panel program, the 3VA1 platform is Siemens' current-generation IEC MCCB family, so long-term supply continuity is the baseline expectation. The nut keeper kit simplifies panel-builder installation — no loose hardware to drop into live gear. The shunt trip coil draws from a 110–127 V control circuit; verify the control transformer secondary matches that range and that the DC rating is observed if using a rectified supply. The two HQ auxiliary switches provide Form C (changeover) contacts for PLC digital inputs or status lamps. They share the breaker's internal mechanism, so no external interposing relays are needed for basic run/ trip indication.","metaTitle":"Siemens 3VA1163-5MH32-0JC0 Circuit Breaker, 55kA @ 415V, 63A","metaDescription":"Siemens 3VA1163-5MH32-0JC0 IEC frame 160 MCCB, 55kA breaking capacity at 415V, 63A, starter protection TM120M, shunt trip, 2 aux switches.
